What is the coating function of a tablet printer?

　　　　With the development of the printing industry and the continuous progress of technology, flatbed printers, as a high-tech inkjet printing equipment that is non-contact with objects, can perform full-color printing without any material limitations.　　General object materials can be printed directly with ink, but some special materials may have the phenomenon of not absorbing ink, or ink is difficult to adhere to its smooth surface, so a coating is needed to treat the surface of the object, so that the ink and printing medium can perfectly combine and present a perfect printing effect.　　The coating must have the ability to firmly adhere to the printing medium and blend well with the ink without affecting the final presentation effect of the ink on the medium.　　Can coatings be universal on various printing media?　　The answer is negative! Coatings are selected for use with printing media and ink. Coatings can take several minutes, such as metal coatings, ABS coatings, leather coatings,
