1. According to the brightness of the three primary colors, the color order: the brightness of the three primary colors of ink is reflected in the spectrophotometric curve of the three primary colors of ink, the higher the reflectivity, the higher the brightness of the ink. Therefore, the brightness of the three primary colors of ink is; Yellow > Green > Magenta > Black.

2. Arrange the color order according to the transparency and hiding power of the three primary colors of the ink: the transparency and hiding power of the ink depend on the difference between the refractive index of the pigment and the connecting material. The ink with strong covering has a greater impact on the color after the overlay, and it is not easy to show the correct color as the post-printing color overprint, and the good color mixing effect is not achieved. Therefore, the ink with poor transparency is printed first, and the post-printing with strong transparency.

3. Arrange the color order according to the size of the dot area: in general, the dot area is small and printed first, and the dot area is large.

4. Arrange the color order according to the characteristics of the manuscript: each manuscript has different characteristics, some belong to warm tone, some belong to cold tone. In the color sequence, the warm tone is mainly printed first black and green, and then red and yellow; The cold tone is mainly printed red first, and then green.

5. According to the different arrangement of the color order of the equipment: under normal circumstances, the printing color order of the monochrome or two-color machine is appropriate to alternate the light and dark colors; Four-color presses generally print dark colors first and light colors later.

6. According to the nature of the paper, arrange the color order: the smoothness, whiteness, tightness and surface strength of the paper are different, flat and tight paper first printing dark color, after printing bright color; Thick, loose paper, first print bright yellow ink, and then print dark color, because yellow ink can cover paper defects such as wool and powder.

7. Arrange the color order according to the drying performance of the ink: Practice has proved that the drying speed of yellow ink is nearly twice that of magenta ink, and the drying speed of magenta ink is twice that of green ink, and the fixation of black ink is the slowest. Slow drying ink should be printed first, dry fast ink after printing. In order to prevent glass transition, the monochrome machine generally prints yellow finally in order to quickly dry the conjunctiva.

8. According to the flat network and the field arrangement color order: when the replica has a flat network and the field, in order to obtain good printing quality, make the field plain clothing, the ink color is bright and thick, generally print the flat network graphics first, and then print the field structure.

9. According to the light and dark color order: in order to make the printed matter have a certain luster and add light colors, print dark colors first, and then print light colors.

10. Landscape products of the green layout text area is much larger than the magenta version, according to the principle of large graphic area of the color plate after printing, it is appropriate to use black, magenta, green, yellow order.

11. Products based on text and black field generally use green, magenta, yellow, black order, but can not print black text and patterns on the yellow field, otherwise due to the small viscosity of yellow ink, black viscosity and reverse overprinting, resulting in black printing can not be printed or printed false phenomenon.

12. For the four-color overprint area of the screen is very small, the color sequence can generally use the principle of a large graphic area of the color plate after printing.

13. Gold and silver products, due to the adhesion of gold ink and silver ink is very small, gold and silver ink should be placed in the last color as far as possible, and under normal circumstances, it is not appropriate to use three overlapping ink printing.

14. The color order of printing should be as consistent as possible with the color order of proofing, otherwise it will not catch up with the effect of proofing.
