Analysis of surface treatment skills in color printing

In recent years, many special printing technologies have been developed for color printing and printing, and printing tools have also developed rapidly. There is a common surface coating (also called spray), surface grinding (also known as sand, namely in Dalian color printing printing surface evenly grinding Ma Sand Point), embossing embossing, pressure process (concave) or pressing printing tool. All of these new color printing finishing technology have been used in the daily use of high-grade packaging, more central china. Especially exquisite handicrafts, cigarette packaging on the common goods prices. The system of digital proof based on hard copy refers to the technology system which prints the printing effect by hard copy, and provides the printing production basis and the user acceptance standard. According to the different type of printing process, respectively, forming a unique offset printing gravure proofing, proofing, proofing, proofing, proofing and flexo printing embossed in different forms and types, but the purpose is to provide the final product acceptance criteria for customers in the printing effect before printing, avoid printing errors, reduce the risk and cost of printing the printing quality assurance.

Color printing is the reproduction of images or text by color (in contrast to black-and-white printing, or monochrome printing). It involves many steps, or transformations, in order to produce high-quality color reproductions. The halftone screen is made of two pieces of glass plate, each glass plate has to fill the ink lines, the two pieces of glass plate vertical bonding together. For each of the color separation film exposed through these screens. High contrast image, once processed, according to the number of received light in the region the formation of different diameters of the prepared outlets, separations of gray image. In the traditional color market, color printing technology is mainly divided into three categories, they are: the production of color image, color and color business. This classification is mainly determined by the output of customer needs. The production of color suitable for mass production, in this field, high production speed and low printing unit the cost is very important. The quality standard of color image work must reach the higher (usually requires accurate color matching), but the amount of this kind of printing parts are generally not large.
