There are several ways to print patterns on metal:

1. Silk screen and flatbed printing: If the area is large and flat, you can use silk screen and flatbed printing, but the color of a single printing is single, and the screen printing cannot print very fine and complex colors. The full color cost is very high. Compared with screen printing, printing can print products with gradual color requirements.

2. Pad printing: the effect is not much different from screen printing, suitable for curved, curved, concave and convex surfaces and individual products that cannot be screen printed.

3. Computer laser engraving or etching: Laser engraving can do fine text and lines, but cannot do color patterns. The color is only white and gray. The effect of etching is worse than that of computer engraving, and it is not so exquisite. If you need color, you need to color it separately.

4. UV ink jet: If the surface is flat and clean and the area is large, you can do UV ink jet, spray color patterns directly on the metal plate, the effect is similar to ink jet, if the requirements are not high, you can do photo or car stickers, and paste directly on the metal surface , This approach has the lowest cost.
