Misregistration is an unavoidable problem in multicolor halftone printing. It causes the loss of detail, sharpness and color hue shift of a reproduction. However, there is a color separation technique called Gray Component Replacement (GCR) which may reduce or eliminate this misregistration effect. An investigation had been conducted using a series of color halftone proofs which were produced by conventional chromatic and GCR color separation techniques. The subjective image quality scaling method was applied to this study as a criterion to determine whether there is an image quality relationship between these two techniques on misregistered reproductions.
