摘要:
A halftone screen generating method includes growing dot centers into uniform binary patterns in an input image, calculating a main distance of each dot center, forming a screen filter by using the main distance, and generating the halftone screen by using the screen filter to form a binary image. The halftone screen generating method controls cluster dots to have a predetermined main distance, and improve a printing quality by growing dot centers uniformly.
