Method for inkjet laser printing on plastic and inkjet laser printing device applying same

Abstract

The invention relates to a method for inkjet laser printing on plastic and an inkjet laser printing device applying the method. The inkjet laser printing device comprises a printing control circuit, an ink box moving mechanism arranged in the X-axis direction and a printing medium moving mechanism arranged in the Y-axis direction. The printing control circuit is electrically connected with a first drive part and a first printing part on the ink box moving mechanism, the printing control circuit is further electrically connected with a second drive part of the printing medium moving mechanism, a laser is further arranged on the ink box moving mechanism. The method for inkjet laser printing on the plastic and the inkjet laser printing device applying the method have the advantages that water-based ink droplets are raised in temperature quickly, are cured and are fused into a plastic surface layer through the laser, and the water-based ink can be applied to plastic medium to conduct jet printing, so that the limitation of oil-based ink required in a traditional plastic jet printing process is eliminated, and pollution to the air and environment caused by using the oil-based ink is reduced.

Description

Technical field [0001] The invention relates to the technical field of printers, in particular to a method for inkjet laser printing on plastic and an inkjet laser printing device applying the method. [0002] Background technique [0003] Inkjet printing is generally achieved by attaching ink to the surface of the printing medium, so there are certain restrictions on the surface of the medium. Water-based ink uses water as a solvent. Water-based ink needs to have permeability on the surface of the printing medium and can be sprayed on the surface of permeable media such as paper, wood, and corrugated cardboard. If oil-based ink is used, it can be printed on the surface of non-permeable media (such as plastic, glass, plastic film, etc.). However, oil-based inks often use organic solvents as solvents (such as methyl ethyl ketone, acetone, ethanol, methanol, hexylene glycol, toluene, xylene, etc.). [0004] The use of oil-based ink will increase the content of organic matter in the ...

AI Technical Summary

Problems solved by technology

[0004] The use of oil-based ink will increase the content of organic matter in the air. These materials are very harmful to human health, and the volatilization of solvents in oil-based ink will also cause air pollution.

On the other hand, if water-based inks are used, they can only be used on media with a permeable surface
