环保印刷品的上光工艺详解（Detailed description of glazing process for environmental protection printed matter） In print, especially on the process of environmental protection printing is the main purpose is to improve the print gloss, increase the abrasion resistance of printed products, light resistance and moisture resistance performance, improve product decoration artistic effect, protect and extend the packaging and decoration printing time, improve the product competition ability, the the production process is relatively simple, low cost, wide application, in the print gloss processing technology in the most competitive. Glazing process refers to the process by which glazing is applied to the surface of printed matter by glazing. The basic process is: the sheet fed from the feeding table input in polishing machine. Polish printing paper rollers in contact with the surface of the roller, polishing rollers in the rotating process, the varnish evenly coated on the surface of printed materials, and then through the drying channel, using hot air, one of several microwave or infrared radiation drying, so that dry thoroughly. It mainly used materials according to the varnish drying process can be divided into oxidation polymerization type, solvent, light curing and heat curing, and performance, the process is mainly divided into the water, the infrared light, ultraviolet (UV) light, light, light on the ordinary PVA card, glazing, heat polishing, polishing, wax sealing colloid screen printing glazing, PP glazing, PVC glazing, heat sealing plastic film on glazing, local stereo. I. water glazing Water based polishing oil (also known as dispersed polishing oil) is the main component of polymer dispersions, dry source requirements are not high, by oxidation, infiltration, absorption, evaporation and drying into film. Technology: can be used coater and almost all types of printing machine glazing, such as offset printing, gravure printing, flexo printing, silk screen and so on. Why is t
