What material needs coating treatment before UV printing

UV flatbed printer is also called universal flatbed printer or flatbed printer. It breaks through the bottleneck of digital printing technology and realizes a real printing, printing without plate making and full-color image printing at one time, which has many advantages over traditional printing process.

Before printing, due to the particularity of the materials, some materials are specially treated and need to be coated to enhance the corrosion effect. What materials need to be processed, and how to deal with them? Share here as follows:

1. Ceramic tiles

Processing method: wipe the surface of the tile with a clean cloth before printing, then use a special spray gun or sprayer to coat the tile uniformly, spray it evenly on the tile surface, and then put the tile in the oven after spraying, use 100-150 Bake at high temperature for 15-30 minutes.

2. Metal

Treatment method: wipe the surface of the metal material with a clean cloth before printing, and then use a special metal coating with a spray gun or sprayer to evenly spray on the surface of the metal material. After spraying, put the metal in the oven and use 100 -Bake at 150 ° C for 15-30 minutes.

3. EVA

Processing method: wipe the surface of the EVA material with a clean cloth before printing, and then use a special EVA coating with a spray gun or spraying machine to spray evenly on the EVA surface. After spraying, put the EVA in the oven and use 80- Bake at 120 degrees for 15-30 minutes.

4. Glass

Treatment method: wipe the surface of the tile with a clean cloth before printing, and then use a special glass coating with a spray gun or sprayer to evenly spray on the surface of the tile, or wipe the coating by hand, and then put the tile after spraying Go to the oven and bake at a high temperature of 100-150 degrees for 15-30 minutes.

5. PE

Processing method: wipe the surface of PE with a clean cloth before printing, and then use a special corona rod for corona treatment, so that the atomic structure of the PE material is not so tightly arranged, and then use a special PE coating with a spray gun or spraying machine The layer is evenly sprayed on the surface of the PE. After the spraying is completed, the PE is placed in the oven and baked at a high temperature of 80-120 degrees for 15-30 minutes.

6. Melamine board

Processing method: wipe the surface of the melamine board with a clean cloth before printing, then use a spray gun or a sprayer to coat the melamine board with a special melamine board, spray it evenly on the surface of the melamine board, and then put the melamine board in the oven after spraying. Bake for 15-30 minutes at a high temperature of 100-150 degrees.

7. Silicone

Processing method: wipe the surface of the silicone with a clean cloth before printing, and then spray the silicone material with a 150-degree flame spray gun to soften the silicone material (it cannot be melted, it is OK when it is slightly soft), and then use the spray gun or spraying machine Use a special silicone coating to spray evenly on the surface of the silicone. After spraying, put the silicone in the oven and bake at 80-120 degrees for 15-30 minutes.

Compared with the traditional printing, the operation process of the UV printer is very simple. It does not need to register and make a plate. It only needs to draw on the computer-put on the board-print-print is completed (one computer, one machine, one employee) No complicated process flow, no high operation cost, multi-colors can be completed at once
