Print Quality Comparison Between Kodak Prosper and Offset Lithography

摘要

Kodak Prosper Imprinting System with stream inkjet technology targets high volume direct mail market and customized products with print quality close to offset output. This study compared the print quality of a Kodak Prosper press and a Heidelberg Speedmaster CD 74 press. The parameters studied were solid/tone uniformity, tone reproduction, rub resistance, and detail reproduction. The lithography samples included typical screen ruling settings of 133 Ipi and 150 Ipi for photograph quality comparison. The samples printed were presented to and evaluated by observers with or without graphic arts experience. The visual comparison and quantitative data were presented. The results showed that Kodak Prosper press has decent print quality with good color appearance. The detail reproduction quality is not comparable with lithography quality.
