Printing proofing refers to delegate accepts demand printing customers (product specifications, model, color), etc. box printing company in Dongguan, make one or more samples to customers to confirm correction. Signed a production contract, to begin production, prepress work is preliminary. Color proofing is to simulate a printed color separations will look like prints. This simulation must be accurate demonstration of the final print of the visual effects, and not necessarily correspond precisely to the film internet point. It should indicate network printing will have increased. Proofing accuracy must be guaranteed, if proofing method used is stable and controllable, able to play accurate proofs. There are many proofing purposes. First, with the proof of the separation process after challenges, provide the film separations without proof test can not immediately say "qualified." Making halftone film of the stage, in essence, a color approximation process is complete, the production of color separations at least be able to print imaging proofing that effect. At this stage we can use less accurate proofing, such as dye sublimation pre-proofing proofing methods. Digital proofing technology is one of the hottest technologies in the prepress area in recent years. The so-called digital proofing, color desktop system is to make the page (or sheets) Data Dongguan box printing, without any form of analog means, directly after a color printer (inkjet, laser or otherwise) output proofs to check for pre-press page image quality process for the printing process to provide reference sample, and can provide the basis for user signature went to press. This digital proofing technology, not simply looking for printed output color proofs, but through complex color management software, the output of proofs can reproduce ancillary printing proofs, including a wide range of matching paper, ink and printability, etc. and similar. 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. Tu little arrangement box printing factory in Dongguan, paint is not uniformly spread throughout the surface to be coated, dried, calendered smoothness difference; dried coating amount is too thick will affect the cost increase. 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.
