Variation of Gravure Printing Characteristic Curves

摘要

Gravure characteristic curve reflects the process of dot transmission. In order to explore the influenceof the various factors on the printing characteristic of gravure, the printing samples were made on a gravurepress with different ink cell shapes, ink viscosity, paper types and reducer component. Curves of printingcharacteristic were drawn and analyzed. The results showed that these factors all had certain influence on theprinting characteristics such as contrast, dot gain, and tone jump on the pressworks.
