Abstract
A method for inspecting whether a print pattern composed of a number of dots is acceptable, an apparatus for inspecting such a print pattern, and an automatic print sorting system are disclosed. A print pattern of an acceptable print sample and a print pattern printed on an article to be inspected are compared with respect to dot distribution, dot density, and other factors. The print patterns on all articles on a high-speed production line can be automatically inspected.
