The difference between automatic screen printing machine and automatic pad printing machine
The automatic screen printing machine is simply called the missing printing, which is to force the ink to leak from the mesh through the squeegee pressure. Screen used, squeegee. Pad printing is to transfer the pattern engraved on the steel sheet to the workpiece through the action of the rubber head, similar to the stamp. Use steel plate and head. In general, the ink layer of the silk screen is thicker than the pad printing, so that the pattern with a thin line is easier to use for pad printing, and the pattern of the large color block is easier to use for silk screen printing.
The automatic screen printing machine ink drying is too fast and easy to block the net, and there will be different stages of color difference when mass production. High-quality pad printing inks are completely dry in just a few seconds when printed onto the product. In the printing process of the automatic pad printing machine, when the glue head takes the ink, the adhesion between the glue head and the ink is greater than the adhesion between the ink and the printing plate, so that the pattern can be completely removed. When printing, the adhesion between the product and the ink is greater than the adhesion between the glue head and the ink, so that the pattern can be completely printed onto the product. And the printing can be printed several times in the same position on the product, the screen can not, the screen can only be printed after the surface of the ink printed on the product is dry, otherwise there will be a high defect rate.
1, the difference between printed products:
A; fully automatic screen printing machine The screen can print large planes (such as: a large area of glass)。 The screen can be printed circumferentially (eg, a cup), also known as a roll。 The screen cannot print fine, fine text。
B; automatic pad printing machine can print irregular products on the surface or products with a stepped structure on the surface, but the screen can not. Pad printing can print fine small text, such as small text on the lens ring of a mobile phone that can be seen with a magnifying glass.
2, printing supplies:
A。 Fully automatic screen printing machine Screen printing machine, screen printing, silk screen printing, screen printing ink, silk screen tooling, etc。
B。 Automatic pad printing machine Pad printing machine, pad printing plate (with thin steel sheet), pad printing head, pad printing ink, pad printing blade or oil cup。
3, from a professional point of view: there is a difference in the use of ink, screen printing needs to be slow to dry, printing needs to dry quickly。 The screen is made of screen ink and is printed with professional pad printing ink。 However, there are many screen inks for pad printing because the price of screen inks is low and many people don't care or don't know that they have a professional pad printing ink。
