Three Principles of UV Flat Printer:

Printing Principle: Printing range, color principle: printing effect, imaging principle: printing efficiency。

1. Printing principle: Ultraviolet flat-panel printers generally use piezoelectric inkjet printing principle, which is different from silk printing, thermal transfer printing, transfer printing and other principles. It can control the ink through the internal voltage of the sprinkler and spray it on the surface of printed products, so it does not need plate making, film making, color matching and other work before printing. Because it is not in direct contact with the material, the ink is sprayed on the surface of the material by spaced inkjet, which widens the range of material printing, such as mobile phone case, glass, nameplate, etc. Ceramic tile, acrylic, metal, leather, textile and other materials can be printed by one machine.

2. Color Principle: The basic colors are C (cyan), M (magenta), Y (yellow), K (black), and W (white), in addition to the others. LM light red, LC light green, LLK light black and spot color, green, silver and other colors, according to the actual material printing pattern needs to match. The right color. Usually, the color software used is photoprint, RIP, Montaigne and so on. These three software functions are similar, they are all edited before pattern printing.

It has the function of white ink and achieves two functions. One is the effect of 3D relief, which uses white ink to build uneven drop on the material surface. Then printing color on its surface to achieve relief effect. The other is to print color patterns on dark materials without white ink. The color you print is absorbed by the dark material, so generally the dark material is first covered with white color.

3. Imaging Principle: Images are dried by chemical reaction of UV ink and ultraviolet light to achieve the effect of instant drying. Ultraviolet ink dries up to 3 seconds after exposure to ultraviolet light.

Because UV ink itself belongs to matte nature, it causes the printing pattern to be dull and not bright enough. In view of this situation, UV varnish (light) can be used. Oil) The pattern surface is coated with transparent varnish to improve the brightness effect.
