The table of the required black granule number from nozzle β flights during to 1 line (1 line) 90.
Black granule number during 1 line 90 of printing longitudinal direction changes with the value of the black particle utilization rate 45 in print parameters.Herein,
Black particle utilization rate 45 is selection (the interval choosing for specifying the black particle that printing is actually used in from the black particle of nozzle output
Take) parameter of ratio, the black particles for being set to export from nozzle using number by the black particle for performing printing it is N number of in 1
In the case of, it is appointed as 1/N uses.For example, it is 1/2 in the case of 1 in using 2.Black particle utilization rate 45 is most
Good value is correspondingly different with print quality and conveying linear velocity.In general, if the ratio of increase selection, can suppress
Influence between Mo Yumo, so can further improve print quality, it can be difficult to the high speed of reply conveying linear velocity.
Herein, in Figure 11 (B) table 91, illustrate during normal when black particle utilization rate 45 is identical printing 47 and it is abnormal when
The black granule number that printing in printing 50 uses.Print what the printing in 47 used when black particle utilization rate 45 is 1/1, when normal
Black granule number 92 is 8, and it is 16 that the black granule number 93 that the printing in 50 uses is printed when abnormal.Equally, black particle utilization rate
45 when being 1/2, and the black granule number 94 that uses of printing printed when normal in 47 is 16, and the printing use in 50 is printed when abnormal
Black granule number 95 be 32.Black particle evenly exports from nozzle, so the black granule number that printing uses is equal to printing and indulged
To the time needed for 1 line 90.That is, in the case where conveying linear velocity and black particle utilization rate 45 do not change, in emergent control
When printing 50 prints when under molding formula to exception, when print the black granule number used needs normal with the time that printing expends
2 times of printing 47.When therefore, in order under emergency flight control pattern to exception printing 50 obtain when printing with it is normal when print
47 same print results, also need to be modified processing in addition to parameters revision.
The method of correcting process has 2 kinds.A kind of is to make conveying linear velocity also slack-off in the case of printing 50 in exception
Method.The correcting process had without the advantages of internally change print parameters can just print.In this case, it is necessary to external portion
Whether notice is in emergency flight control pattern, and this can pass through the place of Fig. 9 flow chart f2 processing r2 or Figure 10 flow chart
N2 is managed to realize.
Another kind is to limit the black particle utilization rate 45 that can be set in advance, to ink in the case of printing 50 in exception
The method that grain utilization rate 45 is printed again after modifying.Specifically, by nozzle α, nozzle β black particle utilization rate 45
When being set to 1/N, N is set as identical even number value in advance.When carrying out normal in this condition in the case of printing 47, nozzle α,
β is printed with the black particle utilization rate 45 of setting respectively.In addition, 50 situation is printed when carrying out abnormal under emergency flight control pattern
Under, the black granule number that normal nozzles use in printing turns into 2 times, so by 2 times of set black particle utilization rate 45
Value (that is, halving N) is modified to new black particle utilization rate 45 and printed automatically.Make the original that N set in advance is even number value
Because being, need to halve use under emergency flight control pattern therefore aliquot value is easily handled, in addition, being set to the original of identical value
Because being each nozzle print control is become simple.
By taking Figure 11 (B) table 91 as an example, as described in the column of " having amendment ", the feelings of printing 47 when normal
Condition, nozzle α, β black particle utilization rate are set to 1/2 without using 1/1, and black granule number 96 now is 16.Afterwards, exist
When turning into abnormal under emergency flight control pattern in the case of printing 50, because the doubles of the particle used, make black particle
Utilization rate is 2 times of the value of setting, is modified to 1/1, and black granule number 97 now is also 16.The correcting process has without becoming
The advantages of more conveying linear velocity.
As described above, in the present embodiment, during emergency flight control when carrying out nozzle, by predetermined ink
Grain utilization rate is modified, and has the print quality identical effect in printing when printing when can make normal and be abnormal.
