พงศ์ยุทธ์ จั่นทอง


The problems of gravure printing proof on Polyethylene Terephthalate Film (PET) are the key color of process colors and the difference in speed of printing condition between gravure proofing machine and gravure printing machine. These affect print quality on polyethylene terephthalate film. The aims of this research were to find color management for proofing with as quality as the inks of gravure printer on polyethylene terephthalate film and to compare the quality of proofing pre- and post- adjust CMYK profile with gravure printings. The experiment was set by adjusting CMYK ink profile to compare the quality of printings. Then, adjusting the viscosity suitable for proofing subsequently, proofing comparison between pre- and post-adjustment of CMYK profile. Post-adjustment of CMYK ink profile found that the coordinates CIELAB value (CIE L *a *b *) of color, the color different (Delta E) and the color gamut quality grain screen were more closely to the gravure printings than the pre-CMYK profile adjustment.
