Do you know the difference between pad printing and silk screen printing?

Pad printing is one of the special printing methods. It is possible to print text, graphics and images on the surface of irregular and heterogeneous objects, which is now an important special printing. For example, the characters and patterns on the surface of mobile phones use this printing method, as well as the surface printing of various electronic products such as computer keyboards, instruments, meters, etc., are all done by printing.

What is the difference between pad printing and silk screen printing ?

Process principle:

Screen printing is a method of first using an image to make a pattern to be printed. The ink is penetrated from the mesh of the screen into the product through the pressure of the squeegee to form a pattern printing area.

Pad printing is to move the pattern engraved on the steel plate to the workpiece through the function of the rubber head, and transfer the steel plate gravure to the printed matter through a specially made silicone printing head. According to the different material of the product, exclusive ink can be made to ensure quality.

Printing area: Printing area:

The screen printing area is basically unlimited, the flat type can be fully printed up to 1500*2000MM, the cost of consumables (screen) is low, and the product shape can be reused.

The printing area of pad printing has a corresponding limit. At present, the upper limit of domestic printing surface can reach 150*450MM, but it is not full printing, but intermittent characters and full printing. The current upper limit of diameter is 300MM, but the cost of consumables (rubber Head) is higher.

Set color: Set color:

The pad printing machine can produce up to 12 sets of colors on one machine, and it can print products at a time with low cost, which is suitable for the investment of ordinary factories.

Screen printing machine can also create multi-colored printing, printing of a variety of colors but the price is very high, investment is not suitable for general factory, large printed manual stage a one-time site of many colors, and more artificial.

The characteristics of the ink layer:

The ink layer of pad printing is thin and can print colors on any surface, showing very good color expression and printing adaptability. Any object can be printed except water and air.

The silk screen has a thick ink layer, a strong three-dimensional impression of the printed pattern, and it is suitable for surface printing of high-quality products. The color expression is very good. Multi-color printing is troublesome. The surface of the product requires regular flat and curved surfaces. There are some Limitation of printing range.
