Embodiment 3
Fig. 7 be utilize twin-jet nozzle and nozzle for longitudinal configuration when, printing during normal in the present embodiment and abnormal time printing in black particle flight example.Wherein, normal print 47 when normally working for nozzle α and nozzle β both sides in Fig. 7 (A) shows black particle flight example 62, printing 50-α time abnormal for nozzle α in Fig. 7 (B) shows black particle flight example 63-α, and printing 50-β time abnormal for nozzle β in Fig. 7 (C) shows black particle flight example 63-β.Herein, what black particle flight example represented is that character is longitudinal.
First, when normal print 47, as Suo Shi Fig. 7 (A), black particle flight example 62 is according to print What correspondingly normal flight.And during nozzle α exception, as shown in Fig. 7 (B), owing to only printing with nozzle β, the scope that nozzle β prints as shown in black particle flight example 63-α is expanded compared with normal print 47 on character is longitudinal, but the hit location of black particle 24 is positions identical with the black particle flight example 62 of normal print 47.
Equally, when nozzle β exception, as shown in Fig. 7 (C), owing to only printing with nozzle α, the scope that nozzle α prints as shown in black particle flight example 63-β is expanded compared with normal print 47 on character is longitudinal.But, because the yawing moment of black particle 24 deflects all the time upward, so the hit location of black particle 24 is different from the black particle flight example 62 of normal print 47, there is the problem of the top movement to character longitudinal direction.
Fig. 8 be utilize twin-jet nozzle and nozzle for landscape configuration when, printing during normal in the present embodiment and abnormal time printing in black particle flight example.Wherein, normal print 51 when normally working for nozzle α and nozzle β both sides in Fig. 8 (A) shows black particle flight example 64, printing 54-α time abnormal for nozzle α in Fig. 8 (B) shows black particle flight example 65-α, and printing 54-β time abnormal for nozzle β in Fig. 8 (C) shows black particle flight example 65-β.Herein, the expression different from Fig. 7 of black particle flight example is pipeline direction.
First, when normal print 51, as Suo Shi Fig. 8 (A), black particle flight example 64 is according to print What correspondingly normal flight.And during nozzle α exception, as shown in Fig. 8 (B), owing to only printing with nozzle β, the scope that nozzle β prints as shown in black particle flight example 65-α is expanded compared with normal print 51 on pipeline direction, but the hit location of black particle is the position identical with the black particle flight example 64 of normal print 51.
Equally, when nozzle β is abnormal, as shown in Fig. 8 (C), owing to only printing with nozzle α, the scope that nozzle α prints as shown in black particle flight example 65-β is expanded compared with normal print 51 on pipeline direction.Further, in the configuration of nozzle α and nozzle β, the scope of the character longitudinal direction that normal nozzles prints does not change, so the hit location of black particle is the position identical with the black particle flight example 64 of normal print 51.
Like this, when only using normal nozzles to carry out Print Control when occurring abnormal, there is print position can the situation of the corresponding movement with the position of normal nozzles, needs to change Print Control.Emergency flight control process f2 for solving this problem is below described.
Fig. 9 is when performing the Jet control flow chart shown in the Fig. 6 (B) in the present embodiment, the flow chart f2 of the emergency flight control process performed when the project 56 " emergency flight control during nozzle " shown in Fig. 6 (A) is " execution ".In Fig. 9, first check at place of branch 66 that it is that abnormal nozzle occurs for which in nozzle α, nozzle β.
When nozzle α is abnormal, by process r1, ink-jet recording apparatus is set as " the emergency flight control pattern " of implementing emergency flight control, and by process r2, emergency flight control pattern is in external notification.Now, the means of notice use display 18 display frame and/or use jockey 33 to carry out communicating, signaling.Afterwards, by processing the mode that 67 are set as only Control Nozzle β, being set as using print parameters N to print by processing 68, printing by processing 69 continuation.
When nozzle β is abnormal, by processing the printing of 70 interruption nozzle β, and show by process 71 message that nozzle β is in abnormality on display 18.Afterwards, the guide of print head position is changed by processing 72 display remindings.This guide in order to whether change print head position for customer selecting shows.This is the countermeasure when print position as shown in Figure 7 is moved, and when place of branch 73 changes print head position, can realize the emergency flight control only carrying out Print Control when abnormal generation by normal nozzles.Physically mobile print head position in process 74, and remove in process 75 and guide, be transferred to printable state by processing 76.Afterwards, after the process carrying out above-mentioned process r1, r2, by processing the mode that 77 are set as only Control Nozzle α, being set as using print parameters N to print by processing 68, printing by processing 69 continuation.
When place of branch 73 does not change print head position, the emergency flight control only carrying out Print Control when abnormal generation by normal nozzles can not be realized.Therefore, in process 78, make guide show minimize and end process.Now, although nozzle does not perform " emergency flight control pattern ", but work under the common Print Control of maintenance.When wanting under this state to change to " emergency flight control pattern ", show by making guide after again maximizing and change print head position in process 73, thus can change to " emergency flight control pattern ".
Process chart when only being undertaken that in the emergency flight control of Print Control, nozzle is removed by normal nozzles when Figure 10 is abnormal generation.Judge abnormal whether releasing at place of branch 79, in discharged situation, check whether at place of branch 80 and to print with emergency flight control pattern.When being once in emergency flight control pattern, check the abnormal nozzle removed at place of branch 81 further.
When the abnormal releasing of nozzle α, remove emergency flight control pattern by process n1, and by process n2 to external notification emergency flight control mode release.Now, the means of notice use display 18 display frame and/or use jockey 33 to carry out communicating, signaling.Afterwards, by processing the mode that 82 are set as control 2 nozzles, being set as using the respective print range of nozzle α, nozzle β and print parameters L (L1, L2), M (M1, M2) to print by processing 83, printing by processing 84 continuation.
When the abnormal releasing of nozzle β, change the guide of print head position by processing 85 display remindings.This guide shows to select whether to change print head position for user.When place of branch 86 changes print head position, common Print Control can be returned.Now, by processing 87 change print head position, removing in process 88 and guiding.Afterwards, the process of above-mentioned process n1, n2 is transferred to.
When place of branch 86 does not change print head position, common Print Control cannot be returned.Now, in process 89, make guide show minimize and end process.In this situation, also do not carry out common Print Control even if nozzle is removed but work under maintenance " emergency flight control pattern ".When wanting to change to common Print Control under this state, show by making guide after again maximizing and change print head position in branch 86, thus common Print Control can be changed to.
As mentioned above, in the present embodiment, when only carrying out Print Control by normal nozzles when abnormal generation, can tackle print position can the situation of the corresponding movement with the position of normal nozzles, even if occur extremely also can obtain the print result identical with time normal, the waste of printing can be reduced.
Embodiment 4
Figure 11 (A) show nozzle α, β in the present embodiment all normal time normal time print 47 and nozzle α abnormal time exception time print the print range of the nozzle β in 50.In addition, the table of the black granule number from nozzle β flight required when Figure 11 (B) is longitudinally 1 line (1 bar line) 90 represented in the print range of printing Figure 11 (A).
Black granule number when printing longitudinal 1 line 90 changes with the value of the black particle utilization rate 45 in print parameters.Herein, ink particle utilization rate 45 is used to specify the parameter being actually used in selection (interval is chosen) ratio of the black particle of printing from the black particle of nozzle output, when will by perform the black particle printed use number be set to the black particle exported from nozzle N number of 1, be appointed as 1/N and use.Such as, be 1/2 when in use 21.The optimum value of ink particle utilization rate 45 is correspondingly different with print quality and pipeline speed.Generally speaking, if increase the ratio of selection, then can suppress the impact between ink and ink, so print quality can be improved further, but be difficult to the high speed of tackling pipeline speed.
Herein, in the table 91 of Figure 11 (B), print when to illustrate when black particle utilization rate 45 is identical normal 47 and abnormal time print the black granule numbers that the printing in 50 uses.When ink particle utilization rate 45 is 1/1, the black granule number 92 printing the printing use in 47 time normal is 8, and the black granule number 93 that printing time abnormal in printing 50 uses is 16.Equally, when black particle utilization rate 45 is 1/2, the black granule number 94 printing the printing use in 47 time normal is 16, and the black granule number 95 printing the printing use in 50 time abnormal is 32.Ink particle exports from nozzle evenly, so print the black granule number used to be equal to the time printed longitudinally needed for 1 line 90.That is, when pipeline speed and black particle utilization rate 45 do not change, under emergency flight control pattern to print during exception 50 print time, print the black granule number that uses and print 2 times that time of expending prints 47 when needing normal.Therefore, in order to obtain the print result same with printing 47 time normal to when printing 50 prints during exception under emergency flight control pattern, also need to carry out correcting process except parameters revision.
The method of correcting process has 2 kinds.A kind of be when exception print 50 make pipeline speed also slack-off method.This correcting process has the advantage that just can print without the need to changing print parameters in inside.In this situation, need whether be in emergency flight control pattern to external notification, this can be realized by the process n2 of the flow chart of process r2 or Figure 10 of the flow chart f2 of Fig. 9.
Another kind limits the black particle utilization rate 45 that can set in advance, the method printed again after modifying to black particle utilization rate 45 when printing 50 when exception.Specifically, when the black particle utilization rate 45 of nozzle α, nozzle β is set to 1/N, in advance N is set as identical even number value.When printing 47 when carrying out normal in this condition, nozzle α, β print with the black particle utilization rate 45 of setting respectively.In addition, when printing 50 when carrying out exception under emergency flight control pattern, the black granule number that normal nozzles uses when printing becomes 2 times, so be that new black particle utilization rate 45 prints by value (that is, the making N reduce by half) auto modification of 2 times of set black particle utilization rate 45.Make the N preset be that the reason of even number value is, needing to reduce by half under emergency flight control pattern uses therefore aliquot value to be easy to process, and in addition, the reason being set to identical value is to make each nozzle Print Control become simple.
For the table 91 of Figure 11 (B), as described in the hurdle of " having correction ", when normal, print the situation of 47, the black particle utilization rate of nozzle α, β does not use 1/1 but is set as 1/2, and black granule number 96 is now 16.Afterwards, when printing 50 when becoming exception under emergency flight control pattern, because the doubles of the particle used, so make black particle utilization rate be 2 times of the value of setting, be modified to 1/1, black granule number 97 now is also 16.This correcting process has the advantage without the need to changing pipeline speed.
As mentioned above, in the present embodiment, during emergency flight control when carrying out nozzle, by revising predetermined black particle utilization rate, have to print when can make normal and abnormal time printing in the identical effect of print quality.
Embodiment 5
Describe the situation that nozzle is 2 in above-described embodiment, but also can consider that nozzle exists the situation of more than 3.This situation adopts the method be synthesized into by the control method in twin-jet nozzle, so use above-mentioned the present embodiment for 3 with any 2 nozzles in top nozzle, can similarly deal with problems.
In addition, as shown in Fig. 7 (C), when nozzle is longitudinally configuration, if the content that will be printed by abnormal nozzle is printed by the normal nozzles be configured on the upside of it, then there is printable character and indulge the problem be moved upward to character, so when the downside of abnormal nozzle exists normal nozzles, preferably support by the normal nozzles being configured in downside.
In addition, by utilizing the normal nozzles adjoined with abnormal nozzle to print the content that will be printed by abnormal nozzle, the print range of normal nozzles can be made to be necessary Min..
