Pad printing basic concepts
Pad printing refers to the need to print the pattern etched on the steel plate (steel), through the pad printing machine oil reel back to the oil, the knife frame combination drop.
The pad printing ink outside the etched pattern of the steel plate back into the oil basin, and then through the adhesion of the glue head, the pattern will be completely panned on the substrate, that is, the completion of the entire printing made.
Pad printing process
With the help of the deformable pad printing head to complete the transfer of ink layer, the pad printing head surface does not contain graphics; the need for graphics first sun and etched into the pad printing intaglio.
And then coated with ink on the surface of the pad printing intaglio, with a hard scraper to scrape the ink on the surface of the printing plate non-graphic area, with the rubber head dipped in the pad printing inks at the plate pit and lift, move to the surface of the substrate for embossing to complete the printing.
Pad printing features
Can print irregular surfaces, but you need a manual, electric, or pneumatic pad printing machine to do, the requirements are high.
The scope of adaptation of pad printing
Pad printing is mainly done through the transfer process of the rubber head, so the pad printing process is limited by the performance and shape of the rubber head.
The glue head has the following characteristics: ① elastic ② curved ③ not infinitely large
Therefore, pad printing can print large-area patterns, but it is very suitable for printing irregular shapes, and uneven workpieces with not certain graphics. Is not achievable by certain printing.
Steel plate and printing quality
The quality of product printing and printing speed, and the depth of the steel plate have a great relationship, depending on the material of the product being printed, the surface light, the size of the pattern, and the base color of the printed material to determine the depth of the steel plate.
1. Depth requirements: the normal depth of steel plate making is generally 0.015mm to 0.035mm, too deep or too shallow will affect the printing quality and production.
2. Hardness requirements: steel plate material selection and processing are also very important, such as the use of low carbon steel, because its hardness after heat treatment can not reach more than HRC62, so in the printing easy to cause wear and tear on the page, invariably resulting in an increase in costs.
3. Surface processing technology requirements: the layout treatment must be plane grinding and then mirror grinding, after these two treatments the steel plate can be printed with high-quality products;
If only plane grinding without mirror grinding of the steel plate in the plate-making process because of the surface capillary holes will indirectly affect the quality of printing so that the quality of the product can not be improved.
The rubber head
Pad printing machine printing head material is a special silicone, made by a special blend of processing, the choice of the product that must be printed by the shape and size of the pattern to choose its softness and shape.
Even require special treatment or reinforcement, given the printing head is stained with ink on the printing plate and will be transferred to the substrate, the head material must have the flexibility and the transfer pattern must be accurate.
The fixed block of the glue head is usually a wooden or aluminum plate. The specific material chosen for the head block depends on the fixing requirements of each pad printing machine.
All standard heads have a common shape: the printing surface is curved and the sides are inclined towards the center. The head is divided into round, square, long, and special shapes.

It is most often reserved for printing wall coverings and the like.
