Abstract

The problem of dot gain, either optical or mechanical, has always been attracting a keen interest of printers mostly from the view-point of tone reproduction. The quality of the light associated with dot gain tends to differ from that not associated therewith, thus the present paper will deal with the effect of dot gain on color reproduction of lithographic print. To predict color cordinates of a monochromatic print from its dot coverage a modification of the Neugebauer equation is proposed which introduces a second color component for each printing ink in order to better describe the colorimetric behaviors of inks. An approach of print quality control based on the colorimetry using the present modification will also be presented.
