There are a variety of printing methods, different methods, the operation is different, printed results also vary. Traditional printing methods used can be divided into: letterpress, offset, gravure printing and stencil four categories. Toppan Printing (Relief Printing) printing surface is usually outstanding, not stamped part is concave, Dongguan box printing quotes, called letterpress printing, Dongguan box printing, letterpress printing include letterpress and rubber version of the two . Typography (Letter press) letterpress printing type is made by early clay and wood type and lead type cast evolved, Dongguan box printing gift box, type layout until modern times most are based, while such a printing method, because it is by the plate directly printed on paper, it is a kind of direct printing. Toppan Printing plates used, in addition to the text of the use of type layout, the other as special fonts or patterns, pictures and the like, using photolithography method to form zinc plate (commonly known as electric version), and more recently to the development of nylon offset, Improved network printing results. General letterpress printed version is flat, Dongguan box printing company, but there are some cases, you need to copy the flat printing plate into a curved shape of the stereotype, which can be mounted on the reel rotary letterpress machine, for a large number of print, such as newspapers. In addition to printing pictures from text, typography plus some accessories, you can also print text pattern embossing the surface, can mutilation printed surface (commonly known as beer-like) and the printed paper is torn with pinhole line and printed automatically translocation and other digital word. Flexographic printing (Flexgraphy) flexographic printing and letterpress printing similar, except that the plate is a piece of soft, like a stamp with a rubber cover. And gravure inks used similar highly volatile and thin, adhesive tape and plastic bags used to print. Influence of Process Factors 1. glazing quality glazing coating process factors affect quality. Substance glazing coating process is the leveling paint coating and drying the printed surface of the process. The main factors are printed coating suitability and performance glazing types and coatings, the coating process conditions. (1) printed glazing adaptability means affect the performance of printed paper and printing graphic printing on coated glazing. In the glazing coating the paper surface paint coating is easy leveling high smoothness. During the drying process, with the coating cured coating, capable of forming a high surface smoothness of the film. Therefore, the higher the paper surface smoothness, glazing coating the better, and vice versa. Absorber paper surface is too strong, the paper fiber absorption rate of coating paint, solvents penetrate quickly, resulting in paint viscosity becomes large, the printed surface of the coating layer increases the flow shear stress, affecting the paint coating leveling difficult to form a smoother film; on the contrary, absorb too weak to make paint coating penetration in leveling the solidification and conjunctiva significantly reduced the role of high-quality film can not be formed on the same printed surface. (2) different types of paint coating, its performance is different, even under the same process conditions, coating, film calendering the resulting situation is not the same. As a light coating viscosity of the coating leveling, wetting has an important impact. The same is inversely proportional to the strength of the paper does not absorb paint coating paint viscosity absorption rate that coating viscosity lower the value, the greater the absorption rate, leveling will end prematurely, causing some local large print surface coating and affect film drying and smoothness and brightness after calendering. (3) selected coating process conditions have a significant impact on the coating quality. Coating arrangement too, it can not be spread evenly throughout the coating surface to be coated, dried, calendered smoothness difference; thick coating will affect the amount of sulfate, and increase costs. Dry thick film layer is applied to the relative increase the pressure and temperature of light when the drying time should be lengthened, which causes the print reduce the water content, the paper fibers become brittle, easily fractured print surface.
