The method of designing clustered-dot screen based on the human visual characteristics and the printer model, the device thereof and the image forming device outputing binary image using the designed screen

摘要

The human visual characteristics and characteristics based on the printer model focusing screen type dot design methods and devices, and is designed screen an image forming apparatus for outputting a binary image is started by using the. Concentration type dot screen design method based on the human visual characteristics and the printer model characteristics according to the invention position information and the human visual characteristics and the printer model, and the cluster centers of the steps of determining the position of the dot cluster centers by a plurality of predetermined manner properties by forming a predetermined sub-dot clusters around the center by using a predetermined algorithm is considered a step of designing the screen. According to the present invention, the order that they are growing around the cluster center with a design with an optimized method according to the printer model of the human visual characteristics and properties have the best picture quality in the printer output image and a dot in the center of the cluster center Because they have banded together to form a strong advantage in printer dipek.
