Abstract

Functions for the visual inspection functions of color defects such as color spots or color stains are required for pattern inspection machines for printed materials. Problems in developing inspection systems for these defects, and color inspection characteristics of the inspection machines are hard to standardize. The authors introduce a calibration method to adjust all aspects of the color evaluation features of the pattern inspection machine to the standard color measurement instrument. Also, the inspection machine adopts human sensitivity to evaluate the color differences which depend on the colors under inspection
