Printing apparatus and printing method

摘要

Printed products can be efficiently sorted into non-defective ones and defective ones even when a discharge failure occurs during the printing operation. Two inspection patterns for detecting discharge failure are printed before and after a plurality of images. The inspection patterns are read to determine the type of discharge failure. Printed media are sorted based on whether it is determined that there is a continuous discharge failure, whether it is determined that there is an accidental discharge failure, or whether it is determined that the discharge is normal.

主权项

1. A printing apparatus comprising:
a printhead having nozzles for printing a plurality of images and inspection patterns on a continuous print medium; a reading unit configured to read and inspect the inspection patterns; a cut unit configured to cut the continuous print medium on which the plurality of images are printed to form a print product; a discharge unit configured to discharge the print product; and a control unit configured to, based on inspection results of two successive inspection patterns inspected by said reading unit, control said discharge unit to discharge the print product which is printed between the two successive inspection patterns discriminately from another print product.
