Paper Color Shade and Gloss Lamination Affect the Print’s Color of Offset Printing

Abstract

The objective of this research was to study the effects of the paper color and gloss lamination on the color prints and the acceptance decisions of the sample group towards the color prints. The three different paper colors were selected in this study; Paper A was white paper, Paper B was bluish-white shade paper and Paper C was reddish-white shade paper. The offset plate with the color test form was made and used to print the samples on the three types of paper which were then taken to gloss laminated on the printed surface. The printed samples on the three types of paper before and after gloss lamination were compared in terms of color value, color gamut, and color difference. In addition, the printed samples were evaluated by a sample group of 30 people. The results of this research found that the color shades of the paper affected the color of the prints as follows: the bluish-white shade of the paper caused the print image to have wider blue gamut and the reddish-white shade of the paper also caused the printed image to have wider red gamut. As the gloss lamination on the printed paper increased the yellow gamut and most affected the green area of the prints. The printed image on Paper A both before and after gloss lamination gave minimal color differences. Whereas using the prints on three types of paper for the sample group to choose from, it was found that more than 50 percent of the sample group opted for the prints on Paper A and the majority justified this by giving the reason that the prints from Paper A produced the most natural color.
