Abstract

See full text

An ink color mixing in an inkjet printing head can be securely detected without being influenced by foreign matters such as the existence of dust and without requiring a complicated image processing. To realize this, the occurrence of a color mixing is detected when a printing density-changed part of a printed image of an inspection pattern continuously extends over a predetermined range or more in a direction in which the printing head is moved relative to the printing medium during the printing of the inspection pattern.
