Brief introduction to the printing process and precautions of high-speed pad printing machine

Random accessories [China Packaging News] pad printing machine is a kind of equipment used for industrial host resonance performance design, which is directly related to whether the system can work and print normally. There are fewer high-tech pad printing companies abroad, and most production companies have moved to China, so the development of high-speed pad printing machine is an inevitable form of development today. The printing process of high-speed pad printing machine is very strange to most people. Now let's introduce it to you

printing process of high-speed pad printing machine

high-speed pad printing machine can be divided into open oil basin and sealed oil cup system, and the operation of rubber head travel action on the two systems is the same

open oil pan:

when the pad printing head moves forward, the oil rod fills the pattern etching printing plate with ink

when the pad printing head moves backward, the scraper scrapes off the excess ink on the steel plate, leaving only the ink on the etched part of the pattern

sealed oil cup system:

when the oil cup is pushed forward, the ink in the cup is sent to the etched position on the printed board, and the ink is filled

when the oil cup returns, the ceramic ring of the oil cup will be like a scraper. The principle of transfer printing is similar to intaglio printing. The tools include silicone pad printing rubber head, patterned printing plate (steel or fiber) and ink, which can print all kinds of extremely thin lines, fonts and patterns, and even four-color plate images. No matter the structure and characteristics of the torsion testing machine, whether the surface of the printed matter is concave, convex or irregular, it can still print the desired effect. For example, printing four-color trademarks on golf balls is one of the specialties of the pad printing machine. Generally, the excess ink is completely scraped away

precautions:

if the ink of the high-speed pad printing machine is too thick, the printing plate will be difficult to clean, resulting in electrostatic problems (hairline); If the ink is too thin, it will increase the transparency, and it is difficult for the pad printing head to transfer the ink

because there are many different inks on the market, it is difficult to determine the time and frequency of adding thinning water or slow drying water. We can only check whether the cooling medium in the cooling tank is working well by observing the printing effect

the above is the printing process of high-speed pad printing machine. I hope you can gain something. For more information, please continue to pay attention to Chinese packaging
