This invention is a Natural Grey Balance Quality Control System. 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. The method can provide a visual referring target on the printing substrate for color balance adjustment. The referring monochrome grey tone is created by a specific halftone of black "K". The neutral grey tone is created by the accurately registered, pre-determined halftone value cyan "C", magenta "M" and yellow "Y" color. By visual comparing both printed tones result, the grey tones color balance can be controlled. This WKTone is a user-friendly system. A qualified press operator can easily visualize any ink value variation by comparing the NGT images with the MGT, which have been placed next to each other against the pre-printed target sample on the proof for confirmation of fine tuning towards balanced NGT mass production.
