Color printing knowledge

The colored printing image is presented through the overprint of cyan, magenta, and yellow primary color inks, which reproduces the colors to replicate the original manuscript image. During reproduction, due to the influence of various processes and production factors, the colors of the printed image cannot well restore the original manuscript colors. In order to achieve satisfactory colored printing image quality, it is necessary to inspect the image color during the printing process and control the color reproduction quality by adjusting certain printing variables.
