  • correction processing methods There are two types of correction processing methods. One is a method in which the conveyance line speed is also slowed at the time of abnormal printing 50. This correction process has an advantage that printing can be performed without changing the printing parameters internally. In this case, it is necessary to notify the outside whether or not it is in the relief control mode, and this can be realized by the process r2 in the flowchart f2 in FIG. 9 or the process n2 in the flowchart in FIG.
  • the other is a method in which the ink particle usage rate 45 that can be set is limited in advance, and when printing 50 is performed in an abnormal state, the ink particle usage rate 45 is corrected to perform printing. Specifically, when the ink particle usage rate 45 of the nozzles ⁇ and ⁇ is set to 1 / N, N is set in advance as an equal value with an even value. When normal printing 47 is performed in this state, the nozzles ⁇ and ⁇ print with the ink particle usage rate 45 set. In addition, when the abnormal printing 50 is performed in the relief control mode, the number of ink particles used for printing by a normal nozzle is doubled. Therefore, a value twice the set ink particle usage rate 45 (that is, N is halved).
  • N is set in advance as an even value is that it is easier to handle a divisible value because it must be halved in the relief control mode, and the reason for setting the same value is that each nozzle print control is easy. It is to make it.
  • the ink particle usage rate of the nozzles ⁇ and ⁇ is 1/1. First, it is set as 1/2, and the number of ink particles 96 at this time is 16. After that, when the abnormal printing 50 is obtained in the relief control mode, the ink particle usage rate is doubled, so the ink particle usage rate is doubled to a value set to 1/1. Correction is made, and the number of ink particles 97 at this time is also 16. This correction process has the advantage that it is not necessary to change the transport line speed.
  • the print quality in normal printing and abnormal printing is made the same by correcting a predetermined ink particle usage rate. There is an effect that can be done.
