The specific embodiment
Below, just be used to implement preferred configuration of the present invention with reference to accompanying drawing and at length describe.In addition, self-evident the present invention is not limited to following example, can at random change in the scope that does not break away from spirit of the present invention.
The coloured image that the present invention for example is applied to formation as shown in Figure 1 forms device 1.It is to be connected to the page printer that personal computer host apparatus 10 such as (PC:Personal Computer) uses that this coloured image forms device 1, comprising: be connected to the host driver 2 of above-mentioned host apparatus 10, the engine controller 7 etc. that is connected to PDL (PDL:PageDescription Language) analysis unit 3 of this host driver 2, the PDL handling part 4 that is connected to this PDL analysis unit 3, the image processing part 5 that is connected to this PDL handling part 4 and RAM (Random AccessMemory) 6 and is connected to above-mentioned image processing part 5.
It is such shown in the flow chart of Fig. 2 that this coloured image forms device 1, receive the usefulness described printable data of PDL (step S1) that sends from host apparatus 10 with host driver 2, resolve (step S2) by 3 pairs of printable data that receive of PDL analysis unit, by handling at PDL handling part 4, generate actual printing image, and the data that will become the bitmap state are launched (step S3) on RAM6.
Then, above-mentioned image processing part 5 will be passed on engine controller 7 is printed on paper in the data of the bitmap state that is unfolded on the above-mentioned RAM6, and discharge finished printing with paper (step S4).
Here, PDL is the language that is used to control the language of page printer or describes printer output, generally speaking, can specify the page printer that does not rely on reality resolution ratio, by the senior print command of abstract.PDL possesses functions such as character and form are set, figure is described.Give printer with the data of utilizing this language to write, in printer, generate image and export.Page printer is if the order of accepting PDL just prints behind the printing image according to calculating one pages such as cutline font reality partly of inside.
In this embodiment, be sent to the data that contain the content of printing color registration correcting chartt the printable data that coloured image forms device 1 from above-mentioned host apparatus 10, form device 1 by above-mentioned coloured image, printing has the reference colours sign of center similar shape consistent with each other and measures the colored printing alignment sign of colour code will on paper, and will be printed on above-mentioned with reference colours sign on the paper and the relative position bias criterion of measuring colour code will be the alignment skew, promptly, colour cast.
The colored printing that forms device 1 printing by above-mentioned coloured image with the alignment sign for example like that, has the reference colours sign of cross shape and measures colour code will shown in Fig. 3 (A), Fig. 3 (B), Fig. 3 (C).
The 1st colored printing shown in Fig. 3 (A) is to be used for discrimination standard look (black) and the 1st to measure the alignment skew of look (cyan), be colour cast that reference colours (black) sign the 111 and the 1st with cross shape is measured look (cyan) sign 112. with alignment sign 110
The 2nd colored printing shown in Fig. 3 (B) is to be used for discrimination standard look (black) and the 2nd to measure the alignment skew of look (magenta), be colour cast that reference colours (black) sign the 121 and the 2nd with cross shape is measured look (magenta) sign 122 with alignment sign 120.
The 3rd colored printing shown in Fig. 3 (C) is to be used for discrimination standard look (black) and the 3rd to measure the alignment skew of look (yellow), be colour cast that reference colours (black) sign the 131 and the 3rd with cross shape is measured look (yellow) sign 132 with alignment sign 130.
Perhaps, the colored printing that forms device 1 printing by above-mentioned coloured image with the alignment sign for example like that, has the reference colours sign of concentric circles and measures colour code will shown in Fig. 4 (A), Fig. 4 (B), Fig. 4 (C).
The 4th colored printing shown in Fig. 4 (A) is to be used for discrimination standard look (black) and the 1st to measure the alignment skew of look (cyan), be colour cast that reference colours (black) sign the 141 and the 1st with concentric circles is measured look (cyan) sign 142 with alignment sign 140.
The 5th colored printing shown in Fig. 4 (B) is to be used for discrimination standard look (black) and the 2nd to measure the alignment skew of look (magenta), be colour cast that reference colours (black) sign the 151 and the 2nd with concentric circles is measured look (magenta) sign 152 with alignment sign 150.
The 6th colored printing shown in Fig. 4 (C) is to be used for discrimination standard look (black) and the 3rd to measure the alignment skew of look (yellow), be colour cast that reference colours (black) sign the 161 and the 3rd with concentric circles is measured look (yellow) sign 162 with alignment sign 160.
For example, under the situation of the colored printing of having printed above-mentioned cross shape with alignment sign 110,120,130, in cyan when the bottom right is offset, as shown in Figure 5, the 1st colored printing with alignment sign 110 in, the reference colours (black) of upside and left side cross shape sign the 111 and the 1st measure occur between look (cyan) sign 112 blank.This is because of the character according to emulation, under the situation of the cross shape sign 112 of having described the 1st mensuration look (cyan) littler on the cross shape sign 111 of reference colours (black) than it, the cause that the cross shape part black of the mensuration look of the 1st among the cross shape of reference colours (black) (cyan) is not printed.
In addition, for example under the situation of the colored printing of having printed concentric circles with alignment sign 140,150,160, in cyan when the bottom right is offset, as shown in Figure 6, the 4th colored printing with alignment sign 140 in, it is overlapping that reference colours (black) sign the 141 and the 1st is measured look (cyan) sign 142, perhaps as overlapping.
Above-mentioned colored printing indicates the sign of respectively measuring look of little chart than reference colours (black) with the printing on the basis of having printed reference colours (black) signs of alignment sign.Though it is less that the sign of respectively measuring look and reference colours (black) sign are compared size, the width of lines and reference colours (black) indicate and are equal to.
Be made as center similar shape consistent with each other by measuring colour code will and Essential colour sign like this, just be easier to detect colour cast with visual.
In addition, as long as above-mentioned colored printing has the reference colours sign of center similar shape consistent with each other and measures colour code will with the alignment sign, each is measured colour code will and reference colours (black) and indicates that compare also can be bigger.
That is, be made as center similar shape consistent with each other by measuring colour code will and Essential colour sign, just can be printed on the reference colours sign on the paper and the relative position skew of measuring colour code will as the alignment skew, be that colour cast simply and is legibly differentiated.
In addition, above-mentioned colored printing is not limited to cross shape and concentric circles with the alignment sign, can be made as arbitrary shape.
And then, though in this coloured image formation device 1, taken place under the situation of colour cast, character according to emulation, measure appearance blank between look (cyan) sign 112 at reference colours (black) sign the 111 and the 1st of cross shape, but as shown in Figure 7, even if under the situation that above-mentioned blank do not occur, to and measure also that ladder takes place between the colour code will 112 is poor at the Essential colour sign 111 of cross shape, be offset as alignment so can will be printed on reference colours sign on the paper and the relative position skew of measuring colour code will according to above-mentioned ladder difference, be that colour cast simply and is legibly differentiated.
In addition, above-mentioned colored printing alignment sign, if among the sign with similar shape, the bigger sign sign 111 ' that for example is made as reference colours as shown in Figure 8 is removed the shape of less sign in the middle of like that, then no matter the character of emulation how, all will between the mensuration colour code will of cross shape and Essential colour sign, take place blank, so can according to above-mentioned ladder difference and blank will be printed on the reference colours sign on the paper and the relative position skew of measuring colour code will as the alignment skew, be that colour cast simply and is legibly differentiated.
In addition, self-evidently bigger sign can also be made as the mensuration look, less sign is made as reference colours.
Here, coloured image in this embodiment forms in the device 1, when the printing of status page (StatusPage), by send the data of the content of printing color registration correcting chartt here from above-mentioned host apparatus 10, as shown in Figure 9, above-mentioned the 1st to the 6th colored printing is printed on on the paper with information such as the setting situation of printer, page info, network state, memory behaviour in service, Installation Options, emulation (Emulation), running stores with the alignment sign, creates color superimposition correcting chartt 100 thus.
This color superimposition correcting chartt 100 is being printed with the 1st to the 6th colored printing in pairs with alignment sign 110A～160A, 110B～160B with the symmetrical position on the paper.
Like this, be printed with in pairs with the symmetrical position on the paper in the color superimposition correcting chartt 100 of colored printing with alignment sign 110A～160A, 110B～160B, not only can be according to each colored printing with alignment sign 110A～160A, 110B～160B, judge alignment skew under the position separately, be colour cast, can also judge that the alignment of direction of rotation is offset, is colour cast by relatively being offset with the alignment of alignment sign 110A～160A colored printing with alignment sign 110B～160B based on paired colored printing.
In addition, though form in the device 1 at above-mentioned coloured image, by sending the data of the content of printing color registration correcting chartt here from stating host apparatus 10, above-mentioned the 1st to the 6th colored printing of printing is with alignment sign 110A～160A on paper, 110B～160B, create color superimposition correcting chartt 100 thus, but also can be for example as shown in Figure 10, the data of the content of printing color registration correcting chartt in storage part 8, have been stored, setting is carried out reading the control part 9 that is printed on behind the printed data of colored printing with the alignment sign with the control on the paper according to order from above-mentioned storage part 8, and forms at above-mentioned coloured image and to carry the function of creating the color superimposition correcting chartt under the user has indicated the situation of establishment of color superimposition correcting chartt in the device 1.
Though in embodiment discussed above, the reference colours sign that will have center similar shape consistent with each other by means of above-mentioned coloured image formation device 1 is printed on on the paper with the alignment sign with the colored printing of measuring colour code will, and will be printed on and above-mentionedly be the alignment skew, be colour cast with reference colours sign on the paper and the relative position bias criterion of measuring colour code will, but the present invention has more than and is defined in above-mentioned embodiment.
In the embodiment that describes secondarily, the printable data that is sent to coloured image formation device 1 from above-mentioned host apparatus 10, include that to form by above-mentioned coloured image that device 1 will count with regulation be that colour cast that unit repeats black (B), cyan (C), magenta (M), yellow (Y) as shown in Figure 11 alternately detects with indicating and is printed on the printed data on the paper, forming by means of above-mentioned coloured image that device 1 will count with regulation is that unit repeats colour cast that point of all kinds forms alternately and detects with indicating and be printed on on the paper, to detect colour cast.
Colour cast shown in Figure 11 detects with indicating that 20 is not have to be printed under the state of colour cast with on the paper, do not having to be printed under the state of colour cast with indicating 20 about this with the detection of the colour cast on the paper, by color attribute being carried out instrumentation in advance by colour meter, and keep the color attribute information that instrumentation arrives, afterwards colour cast is detected with sign and be printed on on the paper, color attribute is carried out instrumentation, just can judge thus whether colour cast has taken place.
Here, the color attribute as carried out instrumentation by colour meter for example has brightness, chroma and form and aspect.Munsell system during colour examining for which kind of can, Meng Saier Munsell system (Munsell Color System), L are for example arranged

For example, under the situation that colour cast takes place as shown in Figure 12, be printed in the colour cast on the paper detect brightness, chroma, the form and aspect measured as the attribute information of color with sign 21 just become be used in the state that does not have colour cast under be printed in the colour cast on the paper and detect with indicating that 20 is different as brightness, chroma, the form and aspect of the attribute information institute instrumentation of color.In addition, in example shown in Figure 12, colour cast takes place in cyan (C) towards the bottom right.
Here, though it is to be that unit repeats black (B), cyan (C), magenta (M), yellow (Y) alternately with the regulation point that the colour cast of printing in coloured image forms device 1 detects with sign, but owing to sensitivity when more then measuring with colour meter as if counting of recurring unit just can't obtain,, preferably get minimum some unit so just need but counting of colour examining is made as recurring unit.
In addition, also can be for example as shown in Figure 13, will by several colour casts detect with sign 20A, 20B ... the colour cast correcting chartt of forming 30 is printed on on the paper, select brightness, chroma, the immediate colour cast detection of form and aspect sign from colour cast correcting chartt 30, and carry out detecting with the correction that indicates according to this colour cast.
Several colour casts detections sign 20A, 20B in the colour cast correcting chartt 30 shown in Figure 13 ... be the result who cyan (C), magenta (M), yellow (Y) has been carried out energetically skew on either direction with the least unit of revising.
Each colour cast detection sign 20A, 20B ... in cyan (C), magenta (M), yellow (Y) under the inclined right one by one of all kinds, the information that on which direction, is offset and so on according to which kind of color make each colour cast detect with sign 20A, 20B ...The quantity of color is thought of as 3 looks (except the black of benchmark), and the direction of skew is thought of as 2 directions, as the pattern of skew by in projects of following table 1, insert+-big or small various values consider pattern miscellaneous (Pattern).
| Cyan | Magenta | Yellow | |||
| Horizontal direction | Vertical direction | Horizontal direction | Vertical direction | Horizontal direction | Vertical direction |
| 0(±) | 0(±) | 0(±) | 0(±) | 0(±) | 0(±) |
Each numerical value of ※ is correction
The combination of table 1, colour cast pattern
