Why should prepress images be screened?

Because the printing process determines that the printing can only use the dots to reproduce the continuous leveling of the manuscript. If the picture is enlarged, it will be found that it consists of countless dots of different sizes. We see that dot size is different, but all occupy the same size of the spatial position. This is because once the original image is screened, the image is divided into countless regularly arranged dots, that is, the continuous adjustment of image information into discrete dots. Image information. The larger the dot, the deeper the color of the performance and the darker the level; the smaller the dot, the lighter the color of the performance, and the brighter the level of representation. The size of the fixed space occupied by each network point is determined by the number of screen lines. For example, the number of screen points is 150 lpi, and there are 150 network points in the length or width of an inch. The location of network space and the size of outlets are two different concepts. For example, the meaning of C50% is that the size of outlets accounts for 50% of the location of the outlets, and 100% refers to the total coverage of the outlets, which is called in printing. "In the field," because there are no outlets, only 0% of the outlets are located in space, so no ink is printed on this place. Obviously, the larger the number of hanging nets is, the smaller the space occupied by the outlets is, and the more layers can be described, the more delicate they are. In fact, the level and color of the manuscript are reproduced through this method of hanging the net.
