Although the laser engraving process and silk screen printing are both used to process various patterns on the surface of the product (water cup), the production principles are completely different.
The laser engraving process is to output the electronic file in the format confirmed by the laser engraving machine after editing by the computer, and burn the surface of the product (water cup) at high temperature by means of the laser engraving machine and high temperature laser rays, and finally form a graphic appearance. If it must be said in layman's terms, it is equivalent to the scar left by high temperature burning, but this scar is traceable, and the set graphics will be presented through computer calculation. There are also many types of laser engraving machines by function, but the working principle is the same. The laser engraving machine belongs to no-plate drawing, and because the laser engraving machine is burned at high temperature, the products engraved by the laser engraving machine mostly show the actual material color of the product (water cup). The surface of the water cup) is engraved with black or red effect, but this is only one color, and a laser engraving machine can change the color of the laser engraving at the same time.
The full name of silk screen printing is screen printing. The working principle is to bask the graphics on the screen plate and perform ink leakage printing through ink. Therefore, silk screen printing is also plate printing. The same screen printing plate can print various colors according to the requirements of the product (water cup) by changing the color of the ink, and it can also print multiple colors on the same pattern at the same time. Now Multi-color screen printing machines have become very popular in the market. Because laser engraving is burning, it is often found that the pattern is concave when touched by hand during processing; silk screen printing does not damage the surface of the product (water cup), so it is printed on it. of. Compared with laser engraving, silk screen printing has richer patterns, the color of the pattern can also be changed, and the silk screen process will not damage the surface of the product (water cup). For some products, due to the material substandard and other reasons, the laser engraved part will appear rust after a little longer after laser engraving.
