Before we buy a screen printing machine or a pad printing machine, we first want to understand their differences so that we can choose the appropriate printing equipment.
Pad printing machine is a kind of printing equipment, suitable for plastics, toys, glass, metal, ceramics, electronics, IC seals, etc. Pad printing is an indirect recessable rubber head printing technology that has become a major method for printing and decorating various object surfaces.
The full name of the screen printing machine is "screen printing machine". It is a device that passes the screen printing ink through the screen onto the surface to be printed according to the shape of the screen openings.
1. Different printing methods:
The screen printing machine is also called leakage printing. It uses the pressure of the squeegee to cause the ink to leak from the mesh.
The pad printing machine transfers the pattern engraved on the steel plate to the workpiece through the pad printing head, similar to stamping.
2. The ink layer after printing is different:
Generally speaking, the ink layer of the screen printing machine is thicker than that of the pad printing machine, so it is easier to use pad printing for patterns with thin lines, and it is easier to use silk printing for large color blocks.
3. Differences in printing products:
Silk screen printing machine: Silk screen printing can print large flat surfaces (such as large areas of glass), or circular printing (such as cups), which is the so-called roller printing. Silk screen printing cannot print fine, small text.
Pad printing machine: It can print products with irregular surfaces or products with ladder structures on the surface, but silk screen printing cannot. Pad printing can also print fine, small text, such as the small text on the lens ring of a mobile phone that can be seen with a magnifying glass.
The pad printing machine can be said to make up for the regret that the screen printing machine cannot print on small areas or irregular substrates. There is no universal printing method in the world, and screen printing is no exception.
Of course, whether it is a screen printing machine or a pad printing machine, the only difference in the inks they use is not the quality of the ink, but what kind of additives are added to the ink.
