Embodiment 1

[0020] A kind of gravure printing process, is characterized in that, comprises the following steps:

[0021] 1) Preparation of silver ink: the silver ink comprises γ-butyrolactone, and the X-ray crystal particle diameter DX dispersed in γ-butyrolactone is 1~15nm, silver particles and basic color printing ink, silver ink The viscosity is 2600mPa·S;

[0022] 2) Corona treatment of the substrate: use a corona device to corona treat the surface of the substrate to increase the surface tension of the substrate and form a polar surface layer;

[0023] 3) Pretreatment of the printing plate: Add the prepared silver ink into the ink tank, and let the gravure cylinder printing plate idle in the ink tank, perform dampening and stirring, and the time for the printing plate to idle in the ink tank is 2 minutes , the plate depth is 20u;

[0024] 4) Adjust the rules: press the finale onto the printing plate, put down the scraper, and make the substrate between the printing plate and the fi...

Abstract

The invention discloses a gravure printing process. The gravure printing process comprises the following steps: 1) preparing sliver printing ink; 2) carrying out corona treatment on printing stock; 3) carrying out printing forme pretreatment; 4) regulating gauge; and 5) formally printing. According to the gravure printing process, sliver printing ink is printed on printing stock subjected to corona treatment, so that adhesion strength of the sliver printing ink is greatly improved, and the sliver printing ink is not liable to drop; sliver particles in the sliver printing ink has sterilization and disinfection effect, and can sterilize and disinfect air and a room to provide a better living environment.

Description

technical field [0001] The invention belongs to the field of wallpaper production, and in particular relates to a gravure printing process. Background technique [0002] Gravure printing is to directly imprint the ink contained in the gravure pits onto the substrate. The shade level of the printed picture is determined by the size and depth of the pits. If the pits are deeper, the ink contained is more. The ink layer left on the substrate after embossing is thicker; on the contrary, if the pit is shallower, the amount of ink contained is less, and the ink layer left on the substrate after embossing is thinner. [0003] Ordinary gravure printing process directly prints on the substrate. After printing, the ink adhering to the substrate is not strong enough, and may even fall off, which affects the quality of the product. At the same time, ordinary wallpaper is only used for aesthetics and is not healthy and environmentally friendly. function. Contents of the invention [...
