A Study of Color Variance between Vacuum Plate of Aluminum and Aluminum Foil Using UV Offset Printing

Abstract

In packaging market, Vacuum Plate of Aluminum by UV offset printing is light impediment effectively, moisture-proof, and forgery-proof and reaches the request of the green packaging production. Thus, the packaging of Vacuum Plate of Aluminum is used widely. This study was a true experimental research. The test form employed was the printing quality control strip from international printing specification. It was used to record and analyze the color variance between Vacuum Plate of Aluminum and Aluminum Foil with white board and no white board using UV Offset Printing. The study indicated the comparison of Tone Value Increased & the difference of Color Gamut Range among these three packaging materials via C, M, Y, K four colors tone value and RGB area testing, and results reveals that the tone value on the Vacuum Plate of Aluminum with white board increased most among these three materials; the dot gain percentage of the Vacuum Plate of Aluminum is less than 15% which with the highest stability than others. All signature findings are given in Fig.1 and Fig.2. These results are entirely consistent with research hypotheses.
