Color correction color document printing color copying process is decomposition of the image information and color reduction combination of both processes. In the actual copying process, because the conditions are not ideal, there is a color difference is inevitable. Its color comes from three aspects: 1, the original color shift due to the photographic process itself and caused material and coloring medium color (color decay) color shift caused. 2, the color separation process light, lenses, filters and photomultiplier tubes error caused by the cast. 3, color reduction process error caused by paper and ink color cast. Must be color corrected. Color correction is necessary to eliminate the chromatic aberration during color copying an objective reality, but also to meet the special requirements when the original color reproduction of color correction. Color correction is usually cyan (Cyan), magenta (Magenta), yellow (Yellow), red (Red), green (Green) and blue (Violet), six colors as a reference. For a certain tone as the basic color of the image can be exaggerated to make the appropriate basic colors and shades to make it to the foot of the printing effect is more prominent, may be appropriate to reduce the amount of the opposite color, to enhance the basic color of purity. Without affecting the overall picture gray balance basis, regional processing methods can be used on the local body color correction. For some gray as the main picture, an appropriate increase in color purity of color enhances the overall visual effect of the image. In short, the color correction is equipment, manuscripts, technology and operations personnel a comprehensive reflection of the quality of color card printing in color reproduction in only master them color card printing custom, it is possible to the original and the actual needs of the user to be the best performance. Printing process open to the general 32 or 16 open single and two-color books color card printing quotes, print run of more than 50,000 in the general arrangement rotary printing machine. Because the rotary machine fast and good printed book pages child had folded printing costs low off than the sheet-fed press. But less than 50,000 books; lead row can be large automatic, automatic or small eight-page printing machine; B-B can be a two-sided offset printing laser typesetting, this printer is designed to print books, press ream calculate printing costs; 01 or 08 monochrome offset printing, such as single-sided offset printing presses, printing costs calculated according to color order. But with the B-B-type offset faster than the single-color offset printing speed and low cost. For printing high quality pictures, should try to use two-color or four-color offset printing; to have a greater field such as paintings, books, etc. should be used before and after the ring lining color offset printing, its print quality is better. Printing should be aware of performance and to calculate the standard price of all kinds of press work, otherwise, it is possible to use unreasonable costly printing process color card printing factory, so book quality decline and increase costs. Printing paper varieties and specifications of the printing paper varieties, many types of standard printed materials, different print often requires the use of different varieties of paper.
