With the progress of the modern era, more and more people are paying attention to their own personality and copyright awareness. The most common is to start printing your own logo on the product. But how do you keep the logo on the product for a long time? This involves two processes for printing logos: laser compliance and screen printing. The next step is to introduce the difference between the two.
Screen printing principle:
Screen printing consists of five main components, namely screen plates, doctor blades, inks, printing stations and substrates. The basic principle of screen printing is to use the basic principle of the screen printing portion to penetrate the ink, and the non-image portion of the grid is opaque to printing.
Laser marking machine principle:
Laser marking is the use of a laser beam to mark a permanent surface on a variety of different materials. The effect of the marking is to expose the deep material by evaporation of the surface material, or to "engraving" the trace by chemical or physical changes in the surface material caused by the light energy, or to burn off some of the material by light energy to reveal the desired etching.
