Talking about the basic knowledge of the three elements of printing platemaking

1, outlets: outlets constitute the smallest unit of printing patterns. Gravure Dots Due to different plate making methods, the dots reflected on the roller are also different: As the dot changes, the size and depth of the dots are also changed along with the change of the net engraving dots; , only changes in the size of the outlets; changes in the laser network outlets are generally reflected in the depth of the outlets.

2. 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 derived from the reflection or transmission of the color light of the solar spectrum. The three primary colors of light in nature are red, green and blue. These three different shades of light can be combined to form numerous shades of light; the three primary colors of pigments are cyan, magenta and yellow. Theoretically, the three-color pigments can be mixed in different proportions. Get all the colors in nature.

3, hard scraping and soft scraping: different installation methods of scraper in gravure printing produce different effects in printing. Hard scraping refers to the fact that the scraper blade is short from the support blade, and the effect is large. The easy-to-wear version of the roller will play a role in solving the problem that the layout is not clean. Soft scratching refers to the longer distance from the blade to the support blade. The effect is that the color tone is gentle and the fog is easy to occur. For the transfer of the shallow part of the version will be a certain help.
