In tinplate printing, in order to improve the adaptability of post-printing and improve the gloss of the appearance and text of tinplate products, the printing ink should be glazed before the printing ink is completely dried to form a uniform and smooth coating film to avoid bleeding. . Coating varnish can not only improve the gloss, but also enhance the flexibility, impact strength, abrasion resistance and adhesion of the surface of the ink layer. In addition, the coating film formed after the varnish is cured at high temperature isolates the ink coating from the outside world and protects tinplate products from physical and chemical substances.
