How to distinguish between the pad printing ink and printing ink
Whether moving printing machine or screen printing machine, cannot leave the ink in the production process.Because the cause of the machine structure, the ink they use is also different.
Screen printing press to earlier than moving printing machine in the printing industry, silk screen printing machine is often used in large areas of the plane early printing products, later, after decades of continuous innovation, to develop curved surface screen printing equipment.But in a small area or irregular substrates on the surface of printing of silk screen printing machine has always been a weakness.Also is precisely the reason later breeds moving printing machine.Pad printing machine can make up for silk screen printing machine cannot be printed on the small area or irregular substrates of regret.
There is no universal way of printing, silk screen printing is no exception.
, of course, whether it is a silk screen printing machine or a pad printing machine, the ink in total as long as they use the difference lies not in the ink is good or bad, but in what kind of ink to add fertilizer.
Pad printing machine actually is the process of ink transfer, also through the pad printing rubber head pad printing ink transfer printing on the plate to carry on the printing process.If the control and the surface tension of the rubber pad printing head pad printing ink close range, its purpose is to improve the printing ink transfer efficiency.
Different process is not identical to the requirement of printing ink, also need to add the appropriate ink supplement ingredients to make them easier to use in detail, such as offset printing ink viscosity is bigger, good resistance to water;Gravure printing ink is thin, active;Silk screen printing ink, will has good permeability.
