Description
Technical field
The present invention, relate to a kind of picture unit, duplicator, printing equipment and printing equipment control program and the printing equipment control method used in the printer of OA machine etc., and print and use data generating device, printing is with data generator and print and to use data creation method, be particularly related to and a kind ofly be applicable to that the particulate with the liquid ink of polychrome is injected in the writings and image of drawing regulation on the print paper (print media), the printing equipment of promptly so-called ink jet type mode, printing equipment control program and printing equipment control method, and print and use data generating device, print with data generator and printing data creation method.
Background technology
Below, to printing equipment, particularly adopt the printer (below, be called " ink-jet printer ") of ink-jetting style to describe.
Ink-jet printer because can easily obtain low price and high-quality colour print product usually, so follow popularizing of personal computer and digital camera etc., is not limited only to office, also extensively spreads among the general user.
This ink-jet printer, generally by integrated possess, the moving body that is called as balladeur train (carriage) of ink cartridge and printhead, on print media (using paper), on the direction that relatively its paper feeding direction is vertical, come and go on one side from the nozzle of its printhead the particle of liquid ink is sprayed (injection) with the ink droplet shape, on print media, draw the writings and image of regulation, make the printed product of hope.And, by in this balladeur train, equipping the ink cartridge of 4 looks (black, yellow, dark red, viridescent) that comprise black (black) and printhead of all kinds, not only black and white is printed, the panchromatic printing that also can easily carry out combination of all kinds (in addition, add 6 looks or 7 looks of shallow green grass or young crops (light cyan) and pale red (lightmagenta) etc. in this each color, perhaps the balladeur train of 8 looks also obtains practicability).
Also have, so make the printhead on the balladeur train on the direction that print paper is vertical relatively, come and go in the ink-jet printer of the type that prints on one side on one side, in order clearly to print a whole page or leaf, be necessary to make tens of times of printhead and even hundreds of above coming and going to move, so with the printing equipment of other modes, for example use the laser printer etc. of the electronic photo technology of duplicator etc. and so on to compare, have the shortcoming that needs a large amount of time-write intervals of cost.Also have, the ink-jet printer of this mode is commonly referred to as " multi-path type printer " or " serial printer ".
Relative therewith, do not use with the printhead of the lengthwise of the width identical (or longer) of print paper in the ink-jet printer of type of balladeur train being provided with size, printhead is moved at the width of print paper, both can carry out the printing of so-called 1 scanning (1pass), so can carry out flying print equally with above-mentioned laser printer.Also have,,, have the advantage that significantly improves quietness in addition so can realize the miniaturization and of printer body because do not need to carry the balladeur train of printhead and the drive system that is used to move it.Also have, the ink-jet printer of this mode is commonly referred to as " wardrobe type (line head) type printer ".
Yet, integral printhead in this ink-jet printer, because with diameter is that fine nozzle about 10~70 μ m separates certain intervals and sets and be 1 row or multiple row is set on Print direction constitutes, so because of manufacture deviation, the ink emission direction of the nozzle of a part can tilt, nozzle location is configured on the position of departing from ideal position, and so-called " flight buckling phenomenon " promptly takes place in spraying the position and can departing from ideal position of the ink droplet that is formed by this nozzle.Also have, bigger as its deviation because the bias property of nozzle, exist quantity of ink to compare more or less with desired quantity.
Its result on the part that bad shower nozzle is printed with this, can be called as the printing problem of " band (banding) (slice) phenomenon ", and print quality is significantly descended.Promptly, if " flight buckling phenomenon " takes place, then the ink droplet spacing by the adjacent nozzles ejection becomes inhomogeneous, distance between adjacent drops with just often compare elongated part on " informal voucher (print paper for white time) " takes place, the distance between adjacent drops with just often compare the part that shortens on " dense " takes place.Also have, when the value of quantity of ink deviates from ideal value, for ink nozzle segment how, also can take place dense, in the few part of ink, informal voucher can take place.
Particularly, this zoning, with the situation of above-mentioned " multi-path type printer " (serial printer) comparatively speaking, fix in " the wardrobe type printer " of (1 scanning and printing) and significantly take place (in multi-path type printer, having to utilize printhead repeatedly to be come and gone make the informal voucher unconspicuous technology that becomes) at printhead or print media.
Therefore, for a kind of bad printing that prevents to cause by this " bar zoning ", make great efforts to improve the research and development on the so-called hardware components such as the manufacturing technology of printhead and design improved, but from manufacturing cost and print quality, technological side etc., providing 100%, that the printhead of " bar zoning " does not take place is very difficult.
Therefore, at present, except the improvement on the above-mentioned this hardware components, also and used that control is printed in as follows being called, just the method on the software reduces the technology of this " bar zoning ".
For example, in patent documentation as follows 1 and patent documentation 2, for not spraying of the deviation of tackling nozzle and ink, be set at: use shade (shading) revisal technology to deal with the deviation of printhead the thin part of concentration, using other color to substitute (for example, substitute be dark green or dark red) when printing with black to the dense part of concentration makes band and deviation not obvious.
Also have, in patent documentation shown below 3, the method that full coat image (promptly spraying the image that becomes cannot see background color) is taked is to increase near the not spray volume of the adjacent nozzle of the pixel of jetting nozzle, and all generate the full coat image with nozzle.
Also have, in patent documentation shown below 4, the departure of each nozzle is fed back to error diffusion handles, the deviation of the ink spray volume of absorption nozzle is avoided the bar zoning.
[patent documentation 1] spy opens the 2002-19101 communique
[patent documentation 2] spy opens the 2003-136702 communique
[patent documentation 3] spy opens the 2003-63043 communique
[patent documentation 4] spy opens flat 5-30361 communique
But, as the prior art of above-mentioned patent documentation 1 and above-mentioned patent documentation 2 etc., use other colors to reduce in the method for bar zoning and deviation, can change because implemented the tone of the part of processing, print this high-quality printing of high image quality that requires so be unsuitable for the photochrome image.
Also have, by to the dense part of concentration, wait the method for avoiding " informal voucher phenomenon " with about the information distribution of jetting nozzle is not given, though can reduce informal voucher when being applied to above-mentioned " flight buckling phenomenon ", but the problem that exists is, still residual on the dense part of concentration have a tape.
Also have, in this methods such as prior art of above-mentioned patent documentation 3,, under the situation of the printed product of middle gray, just can not utilize the method though image is no problem if printed product is full coat.Also have, though for thinner line etc., the words that the method for using other colors to fill up is used once in a while are no problem, and in this image that other colors recur, the problem of existence is identical with the former, and the tone of the part of image can change.
Also have, the problem that exists in this methods such as prior art of above-mentioned patent documentation 4 is, for this problem of the formation content dislocation of ink droplet, the processing of carrying out suitable feedback is very complicated, is difficult to solve.
Summary of the invention
Therefore, the present invention is conceived to this unsolved problem proposition of the prior art just, its purpose is: provide that can to solve or eliminate substantially with the flight buckling phenomenon be the deterioration of the bad image quality that is caused of ejection of the deterioration of the image quality brought of the bar zoning of essential factor and ink, novel printing equipment, printing equipment control program and printing equipment control method and print with data generating device, printing with data generator and printing data creation method.

In addition, in the printing equipment 100, make the established procedure starting of depositing in the regulation zone of ROM64 by CPU60, according to this program, the print processing shown in the flow chart of execution graph 5.Also have, though be used for the printhead 200 of formation ink droplet as above-mentioned, generally the ink droplet of the multiple color of 4 looks and 6 looks etc. can be formed substantially simultaneously, but in order to make explanation be convenient to understand, all use the printhead 200 of (monochrome) of the same colour arbitrarily to form example with all ink droplets and describe (black white image) in the following example.
Fig. 5 is the flow chart of the print processing in the expression printing equipment 100.
Print processing after the CPU60 execution, as shown in Figure 5, at first, is transferred to step S100.
In step S100, in view data acquisition portion 10, the printing indication information of the external device (ED) that connects by the netting twine L that hangs oneself is transmitted, or by printing indication information through input unit 74 inputs, judge whether the indication of printing is arranged, judge that (being) transferred to step S102 when the indication of printing was arranged, otherwise (denying) till being arranged, the indication of printing carries out determination processing repeatedly.
When transferring to step S102, in view data acquisition portion 10, as mentioned above, carry out from external device (ED), CD-ROM, the recording medium of DVD-ROM etc., places such as the storage device 70 of HDD etc. obtain the processing corresponding to the view data of printing indication, judge thus and whether obtain view data, be judged to be when obtaining (being), transfer to step S104 after sending the view data of this acquisition to printing nozzle configuration part 12, otherwise (No), after printing replying that indication unit carries out printing etc., abandon transferring to step S100 after the print processing that should print indication.At this, view data is the data that a plurality of many-valued pixel datas constitute with rectangular arrangement, and its line direction is consistent with the nozzle arrangement direction of printhead 200, and its column direction is consistent with the moving direction (paper feeding direction) of printhead 200.
When transferring to step S104, in printing nozzle configuration part 12, after reading nozzle characteristic information, nozzle information storage part 14 transfers to step S106.
In step S106, in printing nozzle configuration part 12, select the regional pixel data of regulation according to the view data that obtains at step S102, transfer to step S108 then.At this, so-called regulation zone is the data area that comprises the pairing pixel data row of abnormal nozzle in the view data and be positioned near the pixel data row (for example, the pairing row of abnormal nozzle about pixels of 8 row of each 4 row) of the stated number it.
In step S108, based in printing nozzle configuration part 12, the nozzle characteristic information that reads at step S104 and at the pixel data in the regulation zone that step S106 selects, in the printhead 200, judgement for the pixel data in this regulation zone whether corresponding to the crooked abnormal nozzle of flight takes place, be judged to be seasonable (being) transferred to step S110, otherwise (denying) transfers to step S118.
When transferring to step S110, because comprise corresponding to the pixel data that the crooked abnormal nozzle of flight takes place, so in printing nozzle configuration part 12 and in printing with data generating unit 18, pixel data to this regulation zone, the printing data that flight is crooked are considered in generation, transfer to step S112 then.
In step S112, use in the data generating unit 18 in printing, judge whether the generation processing that the region-wide pixel data of view data is printed with data finishes, and (being) transfers to step S114 when being judged to be end, otherwise (denying) transfers to step S106.
When transferring to step S114, in printing, export the printing that generates among the step S108 to printing portion 20 with data, transfer to step S116 then with data generating unit 18.
In step S116, in printing portion 20,, carry out print processing based on from the printing data of printing with data generating unit 18, transfer to step S100 then.
On the other hand, in step S108, the crooked abnormal nozzle of flight takes place in printhead 200 and when transferring to step S118, regulation zone to respective image data, generate by and with the printing data that the common data conversion (2 values processing) of error diffusion processing described later etc. obtains, transfer to step S112 then.
Then, based on Fig. 6, the generation processing of the crooked printing of the consideration of step S110 flight with data is described in detail.
Fig. 6 is the flow chart that printing in the expression printing equipment 100, that consider the flight bending is handled with the generation of data.
This prints with the generation of data and handles, consider that flight is crooked, to the crooked abnormal nozzle of flight and near at least one side of the nozzle it are taken place, the pixel data of whether setting the correspondence in the regulation zone of view data uses this nozzle, set the result based on this, pixel data to the afore mentioned rules zone carries out plug hole processing and concentration value dispersion treatment, and based on the view data generation printing data after this processing, after it is performed in step S110, as shown in Figure 6, at first transfer to step S200.
In step S200, in printing nozzle configuration part 12, the pixel data in regulation zone is resolved, obtain the corresponding relation of each nozzle N of each pixel data in this regulation zone and printhead 200 after, be transferred to step S202.This dissection process, size of images and printing indication information (specifying paper size, printing model etc.) etc. is resolved, obtain the corresponding relation of each pixel data and each nozzle N, but be not limited thereto, also can be by each size and printing model to view data, with the storage in ROM64 etc. of the information of corresponding relation, save dissection process in advance.
In step S202, in printing nozzle configuration part 12, based on the analysis result of step S200 and the nozzle characteristic information that reads from nozzle information storage part 14, whether setting uses the nozzle N corresponding to each of each pixel data in regulation zone, transfers to step S204 then.
At this, in the present embodiment, for the crooked pairing full pel data of abnormal nozzle of flight take place for, do not use the setting of this abnormal nozzle, and, also be set at and do not use for the pairing pixel data of this nozzle to two nozzles with this abnormal nozzle adjacent nozzles of being separated by respectively.That is, for example, in Fig. 3, nozzle N6 is that the nozzle N5 that is adjacent for being separated by and the nozzle N4 of nozzle N7 and nozzle N8 for the pixel data of correspondence, did not use the setting of these nozzles yet when the abnormal nozzle of flight bending took place.
In step S204, in printing nozzle configuration part 12, judge nozzle N use could setting whether finish, is judged to be when finishing (being) and transfers to step S206, otherwise (deny) transfers to step S202, continues to set processing.
When transferring to step S206, in printing nozzle configuration part 12, select the pixel data of regulation from the regulation zone of view data, transfer to step S208 then.
In step S208, in printing nozzle configuration part 12, based on pixel data of selecting at step S206 and the set information of step S202, judge that whether the pixel data of selecting is corresponding to not using nozzle (the plug hole object) data, be judged to be when being the data of plug hole object (being) and transfer to step S210, otherwise (denying) transfers to step S212.
When transferring to step S210, in printing nozzle configuration part 12, the processing of the pixel data plug hole that step S206 is selected in enforcement (make and do not form ink droplet), and neighboring pixels data to the pixel data of this plug hole object, carry out the processing that the concentration value that the pixel data of plug hole object is represented disperses, transfer to step S212 then.In the present embodiment, for example, behind the concentration value separated into two parts that the pixel data of plug hole object is represented, with this two-part value and the represented concentration value addition of neighboring pixels data.
In step S212, in printing nozzle configuration part 12, judge whether whole selected mistake of pixel data and processing finishes, be judged to be when finishing (being), view data after plug hole processing and the concentration value dispersion treatment is sent to printing data generating unit 18, transfer to step S214 then, otherwise (denying) transfers to step S206.
When transferring to step S214, in printing, from the view data after plug hole processing and the concentration value dispersion treatment, select the pixel data of regulation, transfer to step S216 then with data generating unit 18.
In step S216, in printing with data generating unit 18, the pixel data that step S214 is selected carries out 2 values processing, and transfers to step S218.At this, so-called 2 values are handled, in general, be to the multi-value data that comprised in certain number range etc., with the threshold value of regulation (for example, medians in certain number range etc.) compare, coming with this threshold value is the processing of any one party of boundary's numerical value of many-valued data being transformed into two kinds.For example, when in 0~255 number range, having multi-value data, set the threshold to median " 127 ", greatly then be " 255 " if compare the numerical value of multi-value data with " 127 ", if threshold value with next be " 0 ", so multi-value data is transformed into the either party of the numerical value of 2 kinds.In the present embodiment, use data, so be whether on print media, to form ink droplet, for example, be transformed into the processing of the either party in this 2 value as forming " 1 ", not forming " 0 " owing to generate to print.Have again, in the present embodiment, 2 values that formation is not only arranged, do not form, be provided with the formed ink drop size of multiple nozzle according to the represented concentration value of pixel data, each the pairing number range setting threshold of concentration value according to these a plurality of ink drop size, pixel data (many-valued data) and these threshold values are compared, and, pixel data is transformed into the numerical value that expression forms any one party that does not still form for each ink drop size.For example, when ink drop size is N kind (N 〉=2), by to each of each ink drop size, set expression above-mentioned " formations " and because of each different numerical value (at this moment, " not forming " unifies to be made as " 0 ") of this size, with view data N value.
In addition, in the present embodiment, the information of ink drop size is handled in 2 values of each ink drop size each " 1 " of implement forming, " 0 " that do not form, among being judged as " formation ", select maximum ink drop size, and to " 1 " that forms additional its dimension information.
In addition, in the present embodiment, the method that the method for use error diffusion is handled as 2 values, thus the gray scale that can implement under the area gray scale shows.
This error diffusion is handled and is referred to, be that the boundary is when implementing 2 values and handling with many-valued data with certain threshold value, not give up threshold value therewith poor, apply flexibly that this is existing technique known but make in its a plurality of pixel of handling after being diffused into as error.For example, becoming the pixel of gazing at of handling object, in the time of can being " 101 " by 8 (256 gray scale) performance and its gray scale, during 2 common values are handled, because its gray scale is discontented with threshold value (median) " 127 ", so can be used as the pixel processing that " 0 " does not promptly form, " 101 " are directly given up.Relative therewith, when error diffusion is handled, because these " 101 " are spread the untreated pixel around it by error diffusion matrix according to the rules, so for example when only the pixel of selecting the right neighbour of pixel being carried out common 2 values processing, can because being used as " not forming ink droplet ", discontented threshold value handle equally with selecting pixel, yet by accepting to select the error of pixel, its concentration value surpasses threshold value, be subjected to the processing of " formation ink droplet ", thereby can access more 2 value data near original digital image data.
In step S218, in printing,, judge whether the processing of 2 value processing and error diffusion finishes, and is judged to be when finishing (being), finishes a series of processing and returns former processing to stipulating the whole pixel data in the zone with data generating unit 18.
At this, whether the printing data in the present embodiment relate to each of each pixel is formed the data of the size of the ink droplet of specified color and ink droplet thereof, not necessarily whole pixels are formed ink droplets.Particularly, in the present embodiment, to take place the crooked pairing pixel data of abnormal nozzle of flight with and near nozzle (for example, across 2 nozzles with the abnormal nozzle adjacent nozzles) pairing pixel data carries out plug hole, and be dispersed in its neighboring pixels data by the concentration value that the pixel data of this plug hole is represented, reduce by the pixel that the crooked row of flight take place with and near the resolution ratio of the image section that constitutes of pixel, and suppress because of the descend decline of the area gray scale that caused of this resolution ratio.
Then, based on Fig. 7~Figure 12, the action of present embodiment is described.
At this, what Fig. 7 represented is, only by an example of the drop pattern that does not exist black nozzles module 50 that the crooked abnormal nozzle of so-called flight takes place to form; What Fig. 8 represented is, in the black nozzles module 50, and an example of formed drop pattern when the flight buckling phenomenon has taken place nozzle N6.Also have, Fig. 9 (a) is the figure of the part of formed drop pattern when representing generation flight bending shown in Figure 8; (b) be the figure that the situation of corresponding row pixel data plug hole is distinguished nozzle N4, nozzle N6 and nozzle N8 from the drop pattern of (a) in expression; (c) be the figure that expression is dispersed to concentration value the example in the neighboring pixels data of pixel data of plug hole object.In addition, Figure 10 is the figure of an example of each nozzle N of expression ink drop size that can form; Figure 11 is the figure of an example of the dispersal direction handled of the error diffusion of the view data correspondence after the expression plug hole is handled.In addition, Figure 12 (a) is expression by the figure of an example of the drop pattern that the full coat image that the crooked printhead of flight forms does not take place; (b) be expression by the figure of an example of the drop pattern that the full coat image that the crooked printhead of flight forms has taken place on nozzle N6; The figure of drop pattern one example that (c) to be expression form with data based on the printing of the flight bending of considering nozzle N6.
As shown in Figure 7, by the drop pattern that does not exist black nozzles module 50 that the crooked abnormal nozzle of flight takes place to form, above-mentioned the sort of, IOU note or " dense 's " and so on the bar zoning that is taken place by the dislocation at nozzle interval does not take place.
On the other hand, in the print result that obtains by the black nozzles module 50 that comprises the nozzle that the flight bending takes place, as shown in Figure 8, the ink droplet that forms by this nozzle N6, ink droplet one side to being formed by its right adjacent normal nozzles N7 has departed from apart from a this result, between ink droplet that forms by nozzle N6 and the ink droplet that forms by the adjacent nozzle N5 in its left side, IOU note has taken place.
Above-mentioned IOU note, at the printing thing that is so-called " full coat (; be) " here with the image of uniform concentration printing and the part zone of printing with uniform concentration, and print paper is that black etc. is like this under the situation of concentration combination far from it for white, ink, obvious more significantly, the quality of printing thing is worsened terrifically.
On the other hand, do not using black nozzles module 50, and use under other the situation of nozzle module, as mentioned above owing to misplace apart from a because of the bending of flying makes nozzle N6, cause the distance of nozzle N6 and its right neighbour's nozzle N7 to become near apart from a, therefore the density of the ink droplet of these nozzles formation uprises, and this part becomes " dense " and becomes eye-catching, and the quality of printing thing is worsened terrifically.
Therefore, in the printing equipment 100 in the present invention, not only will become the nozzle of the crooked reason of flight, be unusual nozzle N6, also with near the pairing pixel data of the nozzle it, view data plug hole from print object, the resolution ratio of the image section that the flight bent position takes place is descended, thereby make IOU note or " dense " become not obvious, and be dispersed in the neighboring pixels data by the concentration value that the pixel data of plug hole object is represented, can prevent the decline of the area gray scale of this image section, resolution ratio is descended.
At first, printing equipment 100, in view data acquisition portion 10, accept to print (step S100) behind the indication information from external device (ED) etc., from obtaining the pairing view data of this printing indication information there as the external device (ED) in the transmission source of printing indication information etc., and the view data that will obtain sends printing nozzle configuration part 12 (step S102) to.On the other hand, printing nozzle configuration part 12, from nozzle information storage part 14, read nozzle characteristic information (step S104), from the view data of above-mentioned acquisition, select the pixel data (step S106) in regulation zone, pixel data and the above-mentioned nozzle characteristic information that reads according to the regulation zone of this selection, in the black nozzles module 50 of printhead 200, the crooked abnormal nozzle of flight whether corresponding (step S108) takes place in judgement for the pixel data in regulation zone, the crooked abnormal nozzle of flight taking place at once, is transferred to the printing of having considered the flight bending and handles (step S110) with the generation of data.
Considered the generation processing of the crooked printing of flight with data, at first, in printing nozzle configuration part 12, pixel data and nozzle characteristic information based on the regulation zone, from the pixel data in this regulation zone, the processing of the nozzle and near the pairing pixel data plug hole of nozzle thereof of flight bending will take place in enforcement.At this, same as described above, it is crooked that flight takes place for nozzle N6 in the black nozzles module 50, and the print result that is obtained by this black nozzles module 50 is shown in Fig. 9 (a), the ink droplet that forms by nozzle N6, apart from a, therefore, the distance between nozzle N5 and nozzle N6 broadens with just often comparing to the dislocation of ink droplet one side that formed by nozzle N7, on the other hand, the distance between nozzle N6 and nozzle N7 narrows down with just often comparing.Thereby, in printing nozzle configuration part 12, based on nozzle characteristic information the pixel data in regulation zone is resolved (step S200), shown in Fig. 9 (b), the crooked nozzle N6 of flight takes place and respectively across the adjacent nozzles N5 of this nozzle N6 and nozzle N4 and the pairing pixel data of nozzle N8 of nozzle N7, these nozzles N4, nozzle N6 and nozzle N8 be set at do not use (step S202), and, implement these are not used the processing of the pairing pixel data of nozzle from the view data plug hole of above-mentioned acquisition based on this setting content.At this moment, implement the concentration value that the pixel data of plug hole object is represented, be dispersed to the processing (step S208, S210) in the neighboring pixels data of this pixel data.
This dispersion treatment, for example be, to divide the value that obtains behind the represented concentration value of the pairing pixel data of nozzle of (being not limited to divide equally) plug hole object equally, the processing of the concentration value addition that the pairing pixel data of the nozzle that is adjacent is represented, for example, shown in Fig. 9 (c), when being " 26 " as the represented concentration value of pairing certain pixel data of the nozzle N6 of plug hole object, to divide equally the value that obtains after this value (below, be called dispersion value) " 13 ", the concentration value addition that nozzle N5 that is adjacent respectively and the pairing pixel data of nozzle N7 are represented.Equally, will divide " 8 " that obtain behind the represented concentration value " 16 " of the pairing pixel data of nozzle N4 equally, the concentration value addition that nozzle N3 that is adjacent and the pairing pixel data of nozzle N5 are represented; To divide " 18 " that obtain behind the represented concentration value " 36 " of the pairing pixel data of nozzle N8 equally, the concentration value addition that nozzle N7 that is adjacent and the pairing pixel data of nozzle N9 are represented.After concentration value was so disperseed, shown in Fig. 9 (c), the pairing concentration value of nozzle N3 became " 16 " behind the dispersion value " 8 " that adds on its initial value " 8 " from nozzle N4; The pairing concentration value of nozzle N5 becomes " 43 " after adding from the dispersion value " 8 " of nozzle N4 and nozzle N6 and " 13 " on its initial value " 22 "; The pairing concentration value of nozzle N7 becomes " 61 " after adding from the dispersion value " 13 " of nozzle N6 and nozzle N8 and " 18 " on its initial value " 30 "; The pairing concentration value of nozzle N9 becomes " 58 " behind the dispersion value " 18 " that adds on its initial value " 40 " from nozzle N8.Promptly, handle and above-mentioned concentration value dispersion treatment by above-mentioned plug hole, the view data of above-mentioned acquisition is transformed into: nozzle N4, nozzle N6 and the pairing pixel data of nozzle N8 are by plug hole, and as mentioned above, the represented concentration value of they pairing pixel datas is dispersed in the neighboring pixels data.
Then, be implemented the view data of plug hole processing and concentration value dispersion treatment, be transmitted to and print with in the data generating unit 18, there, this view data is implemented 2 values and handles (step S216).
2 values are handled, as mentioned above, it is the concentration value that each pixel data is represented, with in the multiple ink drop size that nozzle can form respectively preset threshold compare, and based on this comparative result, to forming the processing that ink droplet that (" 1 ") still do not form (" 0 ") each ink drop size is set.
In the present embodiment, as the kind of ink drop size, as shown in figure 10, used " greatly ", " greatly ", " in ", " little " these 4 kinds, the represented concentration value of pixel data is " not having ink droplet " printed dot not when the scope of " 0 "~" being lower than 24 "; The represented concentration value of pixel data forms the ink droplet of the size " little " that is equivalent to concentration value " 84 " when the scope of " more than 24 "~" 126 "; The represented concentration value of pixel data when the scope of " more than 126 "~" 212 ", form the size that is equivalent to concentration value " 168 " " in " ink droplet; The represented concentration value of pixel data forms the ink droplet of the size " greatly " that is equivalent to concentration value " 255 " when the scope of " more than 212 "~" 298 "; When concentration value is bigger than " 298 ", form the ink droplet of the size " greatly " that is equivalent to concentration value " 340 ".
2 values are handled, and for example, methods such as use error diffusion are implemented.In error-diffusion method, being configured to the represented concentration value of each pixel data of handling object is α, for little ink droplet, if " α≤84 " then form are " 1 "; If " 85<α " then do not form is " 0 ".Equally, for middle ink droplet, if " 86≤α≤168 " then be " 1 ", if " α<85 " and " 168<α " then be " 0 "; Further, for big ink droplet, if " 169≤α≤255 " then be " 1 ", if " α≤168 " then be " 0 "; Further again, for very big ink droplet, if " 255<α " then be " 1 ", if " α≤255 " then be " 0 ".That is,,,, then ink drop size maximum among these is chosen as " 1 " if there is an expression to form the numerical value " 1 " of ink droplet for above-mentioned 4 kinds ink drop size based on these comparative results; On the other hand, for whole ink drop size, during the numerical value " 0 " that do not form for expression, select " 0 ".
In addition, in error diffusion, can use the error diffusion matrix shown in Figure 11 (b).In addition, in the processing of input text etc., be not limited to error diffusion, can be simply threshold ratio by each pixel decide, in addition,, also can use the method for shake (dither) etc. as other area gray scale technique of expression.
So, to being implemented that plug hole is handled and each of each pixel data of the given area of concentration value dispersion treatment, this pixel data is transformed into one of the value of ink droplet of any size of expression in forming above-mentioned 4 kinds or value " 0 " that expression does not form.For example, be used as representing the value that forms for the information of " 1 " additional representation size, when establish very big ink droplet for " LL1 ", big ink droplet for " L1 ", middle ink droplet for " M1 ", little ink droplet during for " S1 ", be transformed into a value arbitrarily wherein or any one party of " 0 " representing not form.
Also have, as the technical method of control ink drop size like this, for example, in printhead, use under the situation of mode of piezoelectric element (piezo actuator), the voltage that imposes on this piezoelectric element by change comes the spray volume of ink is controlled, and can easily realize.
Above-mentioned 2 values are handled, to be implemented that above-mentioned plug hole is handled and the regulation zone of the view data of above-mentioned concentration value dispersion treatment in full pel ED (step S218), and after the pixel data of the Zone Full correspondence of view data finished (step S112), be implemented the view data that this 2 value is handled, be used as printing and export to printing portion 20 (step S114) with data.
Then, in printing portion 20,, use black nozzles module 50 on print media, to implement ink droplet and form (printing) (step S116) based on from printing printing data with 18 outputs of data generating unit.This forms the result, shown in Figure 12 (c), nozzle N4, nozzle N6 and the pairing ink droplet of nozzle N8 do not form, ink drop size with these nozzle adjacent nozzles N3, nozzle N5, nozzle N7 and the pairing position of nozzle N9, with shown in Figure 12 (b) like that, do not consider that nozzle N6 the ink droplet of the crooked state of flight (not implementing above-mentioned plug hole handles and the concentration dispersion treatment) when generating common printing with data takes place forms the result comparatively speaking, can find out that size becomes bigger.This result, be that dispersion because of above-mentioned concentration value takes place, by the value of being disperseed by pixel data from the plug hole object, nozzle N3, nozzle N5, nozzle N7 and the represented concentration value of the pairing pixel data of nozzle N9, from ink drop size " little " or " " number range, be changed to ink drop size " in " or the number range of " greatly ".Also have, what Figure 12 (a) represented is, based on according to not implementing the common printing data that plug hole is handled and the view data of concentration value dispersion treatment generates, by do not exist take place the crooked nozzle of flight, black nozzles module 50 forms the ideal results of ink droplet on print media normally.Though visual angle from microcosmic, the print result of Figure 12 (c), compare with the desirable print result of Figure 12 (a), undeniable more or less harsh feeling, but visually can identify informal voucher and dense 's phenomenon, compare with the crooked print result that flies of not considering shown in Figure 12 (b), it is more not obvious to become.

Therefore, in printing nozzle configuration part 12, based on nozzle characteristic information the pixel data in the regulation zone in the view data is resolved (step S200), as shown in figure 15, in first row of view data, set nozzle N4, nozzle N6 and nozzle N8 for not using nozzle; In second row, set nozzle N5, nozzle N7 and nozzle N9 for not using nozzle; In the third line, set nozzle N4, nozzle N6 and nozzle N8 for not using nozzle; In fourth line, set nozzle N3, nozzle N5 and nozzle N7 for not using nozzle; In fifth line, set nozzle N4, nozzle N6 and nozzle N8 for not using nozzle, so, the nozzle N that incites somebody to action column position at random in every row is set at and does not use (step S202).Wherein, in the present embodiment, the number that is made as obsolete nozzle in every row is 3.
Then, based on above-mentioned setting content, implement these are not used the processing of the pairing pixel data of nozzle plug hole from the pixel data in above-mentioned selected regulation zone.During plug hole, identical with above-mentioned first embodiment, implement the concentration value that the pixel data of plug hole object is represented, be distributed to the processing (step S208, S210) in the neighboring pixels data of this pixel data.For this dispersion treatment, so because identically with above-mentioned first embodiment dispense detailed description.
Then, implemented the pixel data in the regulation zone of plug hole processing and concentration processing, and be transmitted to and print with data generating unit 18, there, (step S216) handled in 2 values that are implemented the pixel data in this regulation zone.At this, for 2 values are handled, so because identically with above-mentioned first embodiment dispense detailed description.
Above-mentioned 2 values are handled, above-mentioned plug hole was handled and the full pel data in the regulation zone of above-mentioned concentration value dispersion treatment are finished (step S218) to implementing, and after the pixel data of the region-wide correspondence of view data finished (step S112), implemented view data that this 2 value handles and be used as printing and output to printing portion 20 (step S114) with data.
Then, in printing portion 20,, use black nozzles module 50 on print media, to implement ink droplet and form (printing) (step S116) based on from printing printing data with generating unit 18 outputs.This forms the result, as shown in figure 16 as can be known, in first row, the third line, fifth line, the 7th row and the 9th row of view data, nozzle N4, nozzle N6 and the pairing ink droplet of nozzle N8 do not form, the ink drop size of these nozzle adjacent nozzles N3, nozzle N5, nozzle N7 and the pairing position of nozzle N9, form the result with ink droplet shown in Figure 12 (b), when not considering that nozzle N6 takes place generation common printing in the crooked state ground of flight (not implementing above-mentioned plug hole handles and the concentration value dispersion treatment) with data and compare, it is bigger that size becomes.Have again, as shown in figure 16 as can be known, in second row and the 6th row of view data, nozzle N5, nozzle N7 and the pairing ink droplet of nozzle N9 do not form, the ink drop size of these nozzle adjacent nozzles N4, nozzle N6 and the pairing position of nozzle N8, form the result with the ink droplet shown in Figure 12 (b) and compare, form greatly.Also have in addition, as shown in figure 16 as can be known, in the fourth line and the 8th row of view data, nozzle N3, nozzle N5 and the pairing ink droplet of nozzle N7 do not form, the ink drop size of these nozzle adjacent nozzles N2, nozzle N4, nozzle N6 and the pairing position of nozzle N8, form the result with the ink droplet shown in Figure 12 (b) and compare, form greatly.
These results, because of the dispersion of above-mentioned concentration value takes place, reason is identical with above-mentioned first embodiment, so omit explanation.
Have again, though visual angle from microcosmic, the print result of Figure 16, compare with the desirable print result of Figure 12 (a), undeniable more or less harsh feeling, but the informal voucher that can discern and dense 's phenomenon is visually compared with the crooked print result that flies of not considering shown in Figure 12 (b), and it is more not obvious to become.Have again, for informal voucher, because randomly with the ink droplet plug hole, so compare with the print result shown in Figure 12 (c), it is more not obvious to become.
In addition, as shown in figure 17, can will not use nozzle,, on column position at random, set each row of the pixel data in the regulation zone of view data every delegation.In the example of Figure 17, in first row of pixel data, set nozzle N4, nozzle N6 and nozzle N8 for not using nozzle; In the third line, set nozzle N6, nozzle N8 and nozzle N10 for not using nozzle; In fifth line, set nozzle N5, nozzle N7 and nozzle N9 for not using nozzle; In the 7th row, set nozzle N7, nozzle N9 and nozzle N11 for not using nozzle, on the other hand, the even number line of pixel data is not used the setting of nozzle, thereby the nozzle N that incites somebody to action column position at random in each odd-numbered line of pixel data is set at and does not use.Handle by enforcement plug hole like this, and handle with the above-mentioned concentration value dispersion treatment, 2 values of similarly carrying out, can generate a kind of print data, this print data can make the informal voucher that visually recognizes and dense phenomenon, compares and becomes not obvious with the crooked print result that flies of not considering shown in Figure 12 (b).
