The glazing process of coating machines is to apply (or spray, print) a layer of transparent coating on the surface of printed products, and after leveling, drying and calendering, a thin and uniform transparent bright layer is formed on the surface of printed products. During the glazing process of the coating machine, the leveling of the coating on the surface of the printed product enhances the smoothness of the printed product surface, makes the printing texture thicker and fuller, and the color is brighter and brighter, improves the gloss and artistic effect of the printed product, and enhances the appearance of the printed product; improves the surface performance of the printed product, plays a role in protecting the graphics; can improve the grade of the product and increase the added value.
The glazing process of the coating machine includes the coating and calendering of the glazing coating. The process of coating glazing is actually the process of applying the coating (commonly known as glazing oil) to the surface of the paper printed product for leveling and drying. Coating calendering is a process in which the calendering coating is first applied to the surface of the paper printed product with an ordinary coating machine, and then it is hot-pressed on the calender with the help of a stainless steel light belt after drying, and then peeled off after cooling.
Classification of glazing processes of coating machines: According to the glazing paint, it can be divided into oxidative polymerization paint glazing, solvent evaporation paint glazing, light curing paint glazing and heat curing paint glazing; according to the product, it can be divided into full-surface glazing, local glazing, matting and artistic glazing; according to the equipment used for glazing, it can be divided into: glazing with a single coating machine, glazing using a printing unit and linked glazing of a printing press; according to the glazing coating method, it can be divided into: spray coating glazing, printing coating glazing and special coating machine coating glazing; according to the input method of printed materials, it can be divided into manual paper feeding and automatic paper feeding, etc.
