[Ming Bo anti-counterfeiting ink printing network] glazing is in the printed surface has finished printing coated with a layer of colorless transparent coating, obtain a thin film layer of bright.Glazing as the paint on the surface of the printed matter flow, enhance the printing surface smoothness, not only improve the surface gloss of printed matter, but also improved the surface properties of printed products, enhance the performance of the ink of the light, increase the watermark ink layer heat and moisture capacity, to protect and printing, landscaping products role, has been widely used for surface processing book cover processing and packaging, brochures, posters and other printed materials, large decoration in.

 

On many ways, according to the coating can be divided into oxidative polymerization of paint coating, solvent-type paint coating, heat curable coatings glazing, photocurable coating glazing etc..According to the coating method can be divided into spray brush coating, printing coating and special machine coated glazing.If press polishing equipment is divided into the machine and the anti-counterfeiting ink printing glazing machine.In addition, according to the glazing products can also be divided into the whole surface glazing, local glazing, extinction, art.

 

No matter what technology methods and materials for polishing, are required to have excellent polishing quality can reach the expected goal.From the material point of view, the influencing factors of the quality of the light are printing paper, printing ink and temperature change between the coating has good light adaptation.

 

(1) the printing paper.Printing paper effects on the coating is the largest paper smoothness and surface absorption, they influence the coating leveling, influence of coating on the surface of the printed matter formed in Gaoping smooth bright film degree.Paper smoothness high, contact paper surface and coating, coating easy levelling, resulting in the formation of Gaoping smoothness of the film surface.The surface of the absorbent paper, paint flow at ordinary times, the paper fibers absorb paint too fast, the anti-counterfeiting ink coating liquidity, it is difficult to flow.On the other hand, the paper surface absorption is weak, the paper fibers absorb coating is too slow, leveling coating is not easy conjunctival solidification, also it is difficult to form a smooth bright film of Gaoping.Therefore, different paper should be chosen to match the paint, adjust the glazing coating leveling time, drying temperature process.

 

(2) printing ink.Effects of ink particles wetting action of optical variable ink layer which affect the coating leveling and brightness.If the ink particles, the printing surface is rough, is not easy to wet, not easy levelling.

 

(3) coating.The main factors also affect the quality of the light coating, coating should not only have a colorless, tasteless, non-toxic, Hikaruzawa feeling strong, chemical resistance, quick drying performance, but also has good transparency, and not easy to change color, has good flexibility, heat resistance, leveling, adhesion.While the coating effects on the quality of light is the largest of its viscosity, surface tension and the second is the volatile solvent ink.Solvents in coatings due to volatilization, permeability, diffusion effects will be less and less, the viscosity increases.The power flow flat surface tension coating, surface tension in the process to make the coating surface shape of the contraction of minimal surface trace flow into a smooth surface.Therefore, the surface tension convection coating leveling influence.
