Abstract
HD-Flexo printing is the flexo printing technology with 150 LPI and above, which is the key and difficult research in recent years. This paper studied the present half toning algorithms of HD-Flexo and image segmentation algorithm. The Region Growth and Segmentation Algorithm (RGSA) is proposed by theoretical derivation and experiment. The algorithm implements meticulous segmentation of different gray areas of the image (minimum gray scale 0.39%), and effectively reduce the boundary effect of the segmentation region in the segmentation process, which is conducive to the hybrid halftone to form a smooth result.
