Comparative Studies of Print Surface Topography in Offset Printing and Electrophotography

Abstract

In recent years, electrophotographic color printers, with their advance in speed and image quality, are being increasingly utilized in the printing market. However, print gloss of electrophotography outputs have been known to be less consistent with the gloss of the paper used, when compared to the print gloss of offset printing outputs. Gloss is also known to be determined by the topography, namely the three-dimensional profile, of the printed surface.
In this report, it will be explained the difference between surface topography in offset printing and electrophotography.
