Printing color sequence will directly affect the quality of printed products. In order to obtain a good reproduction effect, the following principles must be followed: 1. Arrange the color sequence according to the brightness of the three primary colors: the brightness of the three primary colors ink is reflected on the spectrophotometric curve of the three primary colors ink, the higher the reflectivity, the higher the brightness of the ink. Therefore, the brightness of the three primary inks is; yellow> cyan> magenta> black. 2. Arrange the color sequence according to the transparency and hiding power of the three primary colors ink: the transparency and hiding power of the ink depends on the difference of the refractive index of the pigment and the binder. The ink with strong covering effect has a great influence on the color after over-coloring. As the post-printing color over-printing, it is not easy to show the correct color, and a good color mixing effect cannot be achieved. Therefore, the ink with poor transparency is printed first, and the strong transparency is printed afterwards. 3. Arrange the color sequence according to the size of the dot area: in general, the small dot area is printed first, and the large dot area is printed later. 4. Arrange the color sequence according to the characteristics of the original: each original has different characteristics, some are warm, some are cold. In the arrangement of color sequence, black and cyan are printed first, followed by red and yellow; warm red is printed first, and then blue is printed. 5. Arrange the color sequence according to the different equipment: under normal circumstances, the printing color sequence of the monochrome or two-color machine should be alternated between light and dark colors; the four-color printing machine generally prints the dark color first, and then prints the bright color. 6. Arrange the color sequence according to the nature of the paper: the smoothness, whiteness, tightness and surface strength of the paper are different. Flat and tight paper are printed with dark color first, and then printed with bright color; thick and loose paper are printed with bright yellow ink first. After printing dark, because yellow ink can cover paper defects such as paper wool and powder. 7. Arrange the color sequence according to the drying performance of the ink: Practice has proved that yellow ink dries nearly twice faster than magenta ink, magenta ink doubles faster than cyan ink, and black ink has the slowest fixation. Ink with slow drying should be printed first, and ink with fast drying should be printed afterwards. The monochromator is anti-vitrification, usually printed yellow in order to quickly dry the conjunctiva. 8. Arrange the color sequence according to the flat screen and the field: when the copy has the flat screen and the field, in order to obtain good printing quality, the field flat clothes and the ink color are bright and thick. Generally, the flat screen is printed first, and then the solid structure is printed. 9. Arrange the color sequence according to the light color and the dark color: In order to make the printed matter have a certain gloss, the light color is printed, the dark color is printed first, and then the light color is printed. 10. The cyan version of landscape products is much larger than the magenta version. According to the principle of post-printing of color versions with large areas, the order of black, magenta, cyan, and yellow should be used. 11. Products mainly based on text and black solids generally adopt the order of cyan, magenta, yellow, and black, but black texts and patterns cannot be printed on the yellow solids, otherwise reverse printing will occur due to the low viscosity of yellow ink and large black viscosity. The phenomenon that the black is not printed or is not true is printed. 12. For pictures with a small four-color overprint area, the color registration sequence can generally adopt the principle of post-printing with a large color area. 13. For gold and silver products, since the adhesion of gold ink and silver ink is very small, gold and silver ink should be placed in the last color as much as possible. In general, it is not advisable to use three overlapping ink printing. 14. The color sequence of the printing should be as consistent as possible during the proofing, otherwise it will not be able to catch up with the effect of the proofing.
