First, the outlet: the outlet is a small unit that constitutes a printed pattern. Due to the different plate making methods, the dots reflected on the plate roll are also different: the size of the wire and the depth of the wire are changed according to the change of Wang Cheng; the turbid dot is coated with the mesh. Changes, only the size of the dot changes; the changes in the different meshes of the laser version are generally reflected in the depth of the dot.

Second, color: the color of the object comes from light. Most of the objects in nature are not luminous, such as prints, flowers, and trees. Their color is produced by reflecting or transmitting the color light of the solar spectrum. The three primary colors of light in nature are red, green and blue. The different combinations of the three colors can form a myriad of colors; the three primary colors of the pigment are cyan, red and yellow. In theory, the mixing of the three pigments in different proportions can be obtained. Everything in nature.
Third, hard scraping and soft scraping: the different methods of scraping in gravure printing have different effects in printing. Hard scraping means that the scraper is shorter than the supporting blade, and the effect contrast is large. It is easy to wear the plate roller, which will have a little effect on solving the unclean surface. Soft scraping means that the scraper is longer than the supporting blade, and the effect is gentle and easy to produce fog. It will be helpful for the transfer of the shallow part of the plate.
