Therefore, the effect of supplementing the output data for bad nozzles will disappear
Specifically, will not exhibit expected concentration
[0005] In addition, there is still room for improvement in the countermeasures against nozzle leaks in inkjet recording devices using multi-size dots

[0027] Embodiments of the present invention will be described below with reference to the drawings.

[0028] figure 1 It is a block diagram of a printing system to which the present invention is applied.

[0029] In this figure, a printing head 11 of a printer (droplet discharge device) 10 discharges four or six color inks supplied from ink tanks from nozzles. The printing heads 11a to 11d are fixed at predetermined positions, and the platen 12 is rotationally driven by the platen motor 13 so that the paper is conveyed so as to cross the printing heads 11a to 11d. The print heads 11a to 11d are arranged zigzag in a zigzag shape toward the longitudinal direction, and the nozzles face the paper so as to span the entire width of the paper in the width direction. Accordingly, it can be said that the printing heads 11a to 11d relatively move on the paper.

[0030] The feed motor 14 drives a paper feed roller 15 that feeds paper stored in a predetermined paper stacker. A printer...

no. 2 approach

[0159] In the previous first embodiment, the processed ink shortage amount and the carried-over ink amount were calculated for each pixel. Although the insufficient amount of density can be accurately calculated, the amount of processing increases due to calculation. In addition, there is also a viewpoint that it is impossible to reliably and uniformly determine whether the corrected value of the density obtained by distributing the amount of ink to adjacent dot positions is a correct value based on the ink amount data obtained by calculation. . In particular, if the relationship between the dot value and the ink amount is not proportional, it cannot be said that the calculation result based on the dot value is the correct value for the insufficient ink amount.

[0160] Figure 9 is a diagram showing the contents of the substitution table.

[0161] In this embodiment, using Figure 9 In the replacement table shown, the value of the insufficient ink amount to be allocated t...

Abstract

The present invention maintains the concentration even in the presence of defective nozzles. A specifying section specifies in printing data a first dot position at which a defective nozzle dischargesan ink droplet to print the ink droplet on a medium when the defective nozzle is not defective, but is normal, and specifies in printing data a second dot position different from the first dot position based on priority information in which priority is set for each pixel. A data correcting section corrects the printing data. The collecting corresponds to allocating an amount of ink of the first dot position to the second dot position. When the first dot position at which the ink droplet is provided to the medium if the defective nozzle is not defective is specified, a neighboring second dot position different from the first dot position is specified based on the preset priority information, and the data correcting section corrects the printing data so as to allocate the amount of ink to the second dot position based on the mount of ink of the first dot position.

Description

technical field [0001] The present invention relates to a printing control device, a printing control method, and a medium recorded with a printing control program that perform printing by intermittently conveying a printing medium in a sub-scanning direction while reciprocating a printing head in a main scanning direction. Background technique [0002] In an inkjet recording device, the diameter of the nozzle is required to be reduced for the purpose of improving quick-drying performance and high definition. Since the diameter of the nozzle is reduced, the nozzle is likely to be clogged due to solidification of the ink. When a nozzle is clogged and ink cannot be ejected, white streaks are generated at the position corresponding to the nozzle. [0003] In Patent Document 1, there is an output data changing unit that obtains a logical sum of the output data of a nozzle and the output data of any one of the nozzles adjacent to the nozzle, so as to change the output data of th...
