초록
Print gloss is an important attribute of the final printed product. While past work has looked at the influence of key aspects of the coating structure on print gloss, a systematic study has not been reported. The coating roughness, porosity, and pore size are changed by using various combinations of coating materials and by calendering against rough plastic sheets. The print gloss is measured every tenths of a second right after printing, a few minutes after printing, and a few days afterwards. Roughness and porosity affect the print gloss for the first two seconds: this result shows that they influence the ink-film splitting event. Once ink film starts to level, roughness and pore size influences the level of print gloss within the first ten seconds after printing. Porosity modifies the evolution of print gloss for the next few minutes. The decrease in gloss at long times is found to correlate to surface roughness.
