APPARATUS AND METHOD FOR CONTROLLING INKJET PRINTER

摘要

A control device and method of an ink-jet printer are provided to obtain uniform chromatics concentration over the whole print width by a plurality of printer heads without complicated task even when the discharge property of each printer heads is irregular. A control device of an ink-jet printer includes a detection unit(80) detecting the coating state of the ink coated on a printing medium, a comparison unit(122) comparing the detected coating state, and a correction unit(123) amending the discharge control value of a discharge control apparatus according to the comparison result. A control method of the ink-jet printer is as follows. A plurality of printer heads(60A~60D) discharge the ink at the same concentration according to the discharge control value and a plurality of head correspondence coating domains corresponding to the printer head are formed. The detection unit(80) detects the coating state of the ink at each head correspondence coating domain. The comparison unit compares the ink coating states of the head correspondence coating domains. The correction unit sets up the correction value of the discharge control value according to the comparison result in order to make the ink coating states of the printer heads the same.
