Abstract
A print quality control method, comprises the steps of: providing a visual referring target on the printing substrate, setting a specific halftone of black “K”; creating a neutral grey tone i.e. NGT; placing tightly both MGT and NGT next to each other across the printing surface; and comparing both printed tones result. By adopting the grey balance theory and visual matching technique, the resultant can provide accurate ink balance information for the production personnel to immediate execute the correction on the imbalance inking condition during production.
