Can UV Flatbed Printers Really Be Free Of Coating?

What is the coating-free of UV flatbed printer? How to avoid coating? What are the advantages? These three are difficult problems that plague new users. For example, the difference between them is not well understood, and it is very simple to cause a lot of trouble in the use of later equipment. Seriously, you may buy equipment that you can't use at all, and waste money.

Coating-free UV flatbed printer means that when printing part of the material, it can start printing without pre-pressing the surface of the material. It does not mean that all materials can prevent coating printing. This coating-free printing is conditionally restricted.

For example, coating can be prevented on the surface of plastic materials, such as mobile phone shells and notebook shells. Gypsum ceilings commonly used in building materials can also prevent coating printing; however, some cannot be printed without coating, such as glass, glazed tiles, metals and other high-density and smooth materials that cannot be directly printed.

So, how to avoid coating? Coating-free is actually determined by the ink. The corrosive nature of UV ink itself can make fine (invisible to the naked eye) corrosion on the surface of the material. During this process, the pigment components in the ink can be attached to the material. Surface, complete the entire printing process.

Of course, UV flatbed printers now have some inks that are free of coating on the glass. In fact, it is added with a distributed chemical agent. It seems that one process is missing, but the loss is even greater. If it is an industrial sprinkler, no problem. If the small nozzle is selected, the purity of the ink will be reduced, and the impurities will increase. The result is that the nozzle is blocked in a short time and is scrapped.
