What materials need coating 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 single printing, no plate making, and full-color image printing. It has many advantages compared to the traditional printing process.

Before printing, due to the special nature of the material, some materials need special coating to enhance the corrosion effect. What materials need to be processed, and how to handle them? Here are the following:

1. Tile

Treatment method: wipe the surface of the tile with a dust-free cloth before printing, and then spray the surface of the tile with a spray gun or sprayer with a special tile coating, and then put the tile in the oven after spraying. Bake at a high temperature for 15-30 minutes.

2. Metal

Treatment method: wipe the surface of the metal material with a dust-free cloth before printing, and then spray the metal surface with a spray gun or sprayer with a special metal coating uniformly. -150 ° C for 15-30 minutes.

3. EVA

Treatment method: wipe the surface of the EVA material with a dust-free cloth before printing, and then spray it on the EVA surface with a spray gun or sprayer with a special EVA coating. After spraying, put the EVA in the oven and use 80- Bake at 120 ° C for 15-30 minutes.

4. Glass

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

5. PE

Treatment method: wipe the surface of PE with a dust-free 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 spray gun or a sprayer to coat it with a special PE Layer, spray uniformly on the surface of PE, put the PE in the oven after spraying, and bake at 80-120 degrees for 15-30 minutes.

6. Melamine Board

Treatment method: wipe the surface of the melamine board with a dust-free cloth before printing, and then use a spray gun or sprayer to coat the melamine board with uniform spray on the surface of the melamine board. After spraying, put the melamine board in the oven. Bake at 100-150 degrees for 15-30 minutes.

7. Silicone

Treatment method: wipe the surface of the silicone with a dust-free 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 if it is slightly soft), and then use a spray gun or sprayer Use a special silicone coating, spray evenly on the surface of the silicone, put the silicone in the oven after spraying, and bake at 80-120 degrees for 15-30 minutes.

Compared with traditional printing, the operation process of UV printer is very simple. It does not need to register and make plates. It only needs to make drawings on the computer-put plates-print-printing is completed (a computer, a machine, an employee (No need for complicated process flow, no high operating cost, multiple colors can be done in one go)
