Colorimetric measurements are carried out on the various color samples in order to investigate the influence of the screen rulings. It is noted that in the case of off-press proofs there is not much difference in the colorimetric characteristics between 175 lines/inch and 600 lines/inch, whereas in the case of prints there is bigger difference. It is also noted that the differences caused mainly by the mechanical dotgain of printing inks and optical dotgain has little effects.
