Problems solved by technology

Although this reduces the difficulty of making the glazing rubber roller and the possibility of varnish polluting the weld groove, it increases the consumption of varnish and gas, which is not conducive to energy saving and emission reduction
Moreover, the blank part left horizontally between the single modes is a metal substrate, for example, plain iron, varnish is directly coated on it, the adhesion is poor, it is easy to fall off, and the layout is polluted

Abstract

The invention discloses a printing and coating method for metal UV (Ultra Violet) color printing products. The method comprises the following steps: 1) directly platemaking through a computer; 2) internally coating, adopting a paint to coat the inner surface of a metal substrate; 3) instantaneously and continuously finishing UV bottom oil coating, UV bottom oil curing through a UV lamp and UV ink printing; 4) continuously solidifying and drying UV lamp sets; and 5) polishing and coating gloss oil on printed patterns on the outer surface of the metal substrate through a polishing rubber roll on a coating machine. According to the method, the tedious procedures of a traditional film publishing can be saved; furthermore, the UV bottom oil external coating is adopted to replace a traditional solvent type bottom oil external coating, and a film is thin, so that a plurality of fuel gas energy can be saved, and the effects of energy conservation and environment protection can be realized; meanwhile, an empty slot is additionally formed in the traditional polishing rubber roll, and the gloss oil is coated on the image-text surfaces of simple modules on the metal substrates, so that the dosage of coating the gloss oil on margins among the simple modules on the metal substrates in a traditional polishing technology, the production cost can be saved, and energy conservation and emission reduction can be beneficially realized.

Description

technical field [0001] The invention relates to metal UV printing and coating technology, in particular to a printing and coating method for metal UV color printing products. Background technique [0002] In the field of traditional metal printing, the CTF (Computer to Film) process is used for pre-press plate making, that is, the graphic data information is processed by the computer, and then the film is printed before printing; the primer coating generally adopts the traditional solvent-based coating. Coating, thermal curing mode, needs to burn a large amount of gas to dry the coating, which is not conducive to energy saving; printing method adopts thermal curing mode, uses thermal curing ink and gas drying room to dry ink, consumes a lot of energy and emits a lot of waste gas, which is not conducive to energy saving and reduction. Row. [0003] In the field of metal printing, products need to be coated and polished after printing to increase the surface gloss of printed ...
