Abstract:
1. A print quality control method, comprising the steps of: providing a visual referring target on a printing substrate for color balance adjustment; setting a specific halftone of black “K” as a referring monochrome grey tone (MGT); creating a neutral grey tone (NGT), by accurately overprinting a cyan “C”, a magenta “M”, and a yellow “Y” color according to a pre-determined halftone value percentage; placing tightly both MGT and NGT next to each other across a printing surface; and comparing both printed tones result to control the grey tones color balance; wherein: the referring monochrome grey tone “K”, MGT is replaced by 100% single color and 50% halftone in a form of CMYK grouping, thereby providing additional printing condition information to an operator.
