A: Because the printing process determines the printing can only use the network to reproduce the original tone of the continuous level, if the enlarged view, you will find that there are numerous sizes ranging from the network. We see the dot size is different, but all occupy the same size of the space position, this is because the original image after screening, the image is divided into numerous rules of the network, that is, continuous tone image information into a discrete network Image information. The larger the dot, the deeper the color of the performance, the darker the hierarchy, the smaller the dot, the lighter the performance, the brighter the level. Uv printing factory manufacturers each network occupied by the fixed space position size is determined by the number of lines, for example, the mesh point of 150lpi, then in an inch of length or width of 150 outlets. The location of the dot space and the size of the network are two different concepts. For example, the C50% means that the dot size accounts for 50% of the network space. 100% refers to the size of the network covering all the dotted space, Field ", 0% because there is no network, only the location of the network space, so this place there is no ink was printed. Obviously the greater the number of hanging mesh, the smaller the space occupied by the network, the more the level can be described, the more delicate. In fact, the level and color of the original document is reproduced through the method of hanging the net.
