Glazing effect on printing effect

  What are the implications glazing way for color printing effect?
  
The effect of different methods of glazing color printing is also different, the following table describes the different ways of glazing of color printing effect:
Glazing types The main raw material Drying methods Effect of processing The impact on the color printing color The impact on the environment use
Ordinary glazing Solvent, oily gloss coating, made from toluene and ethanol dispersion medium Infrared electric thermal curing of the type of solvent evaporation Brightness is general, abrasion resistance is poor The whole yellowing, comprehensive network spread Toluene steam damage to the environment, harmful to human body health, easy to cause fire Publications cover, cartons and labels
UV glazing PU (polyurethane) UV ultraviolet (UV) light curing High brightness, good wear resistance Yellowing occurred Smell migration is lower than the ordinary glazing and PVA polishing, ozone smell slightly The food in cartons and other paper products processing
Inferior smooth grain type polishing (sand), and other special effects UV glazing coatings (Gao Liangguang type, second type) UV light curing High brightness, good wear resistance A slight yellowing Smell migration is lower than the ordinary glazing and PVA polishing, ozone smell slightly Advertising, bags, book covers, poker, senior carton, etc
Emulsion glazing oil (water) Paper absorbed by natural drying curing temperature Brightness is very good, good abrasion resistance No color difference Only water vapor discharge, no pollution
PVA polishing Glazing coating, PVA resin made from vinyl acetate dispersion medium Infrared electric thermal curing of the type of solvent evaporation Brightness is good, wear resistance is poor Slightly yellowing, branches spreading Solvent evaporation caused environmental migration and smell Publications cover, paper box and tags
Resin letterpress or reticulate version of local glazing Solvent, oily gloss coating, or UV glazing coating The infrared thermal curing, UV light curing With no glazing, compared to other parts of the brightness and abrasion resistance are improved obviously A slight yellowing Smell migration is lower than the ordinary glazing and PVA polishing, ozone smell slightly The food in cartons and other paper products processing
