Two-dimensional Digital Halftoning Based on Weighted Least-squares for Laser Carving Gravure Cylinder Technology and Detecting System of Ink Cells via Neural Network

Abstract

Laser carving technology has the advantages of higher resolution, focusing precision and digital modulation. It has been widely used in laser engraving gravure plate and laser plate processing. However, the switching of the laser has only two states, so the halftoning processing plays a vary important role in the laser plate. In this paper, we present a 2… (More)
