Description

A kind of gloss oil and composite coating of Laser Jet
Technical field
The present invention relates to the technical fields of coatings for tin plate printing, and in particular to a kind of gloss oil and composite coating of Laser Jet.
Background technique
It is conventional process that Laser Jet, which makes a check mark, on the packing jars such as can, beverage can, and with Internet technology Progress, scans the two-dimensional code the information and identity to identify product, more and more common, therefore, two dimensional code is introduced into food, beverage And on the packing jar of other common consumer products.
Currently, the two dimensional code on packing jar is largely made by way of Laser Jet, on packing jar generally at least Layer of transparent protective coating, laser, which directly burns coating, gets two dimensional code;Due to coating transparent, compared colour difference is unobvious, and applies For layer because breakdown has destruction, long-term exposed ground can play rust, easily cause two dimensional code mark unintelligible, discrimination is low.Therefore, producer's meeting On packing jar after first printing ink layer, then upper layer of transparent protective layer, with the stamp on ink layer, to solve compared colour difference Unconspicuous problem.But when Laser Jet, laser power control difference equally will appear the problem of puncturing ink layer, especially It is that after food cans are placed by sterilization process or for a long time, will appear the defects of ground plays rust, two dimensional code is unintelligible.
Therefore the composite coating of existing Laser Jet has much room for improvement.
