The printing ink color sequence arrangement has the following special requirements:

1. When printing securities, generally print the pattern first, then print the pattern, text and numbers.

2. When copying an original such as a color print, the print color sequence should be as consistent as possible.

3. New-year prints, calendars, etc., which have a special color border, and the spot color frame is usually printed last.

4. It is necessary to use the printing process of the printing process, and the color sequence of the printing is generally opposite to the color sequence of the printing.

5. There are glazing, hot stamping (hot aluminum), printed matter required for film coating, generally printing ink in the process, after glazing, bronzing and laminating. However, for some special requirements of printed matter, when it is necessary to print other colors on the electrochemical aluminum, the above process must be changed, and it is necessary to pay attention to the adhesion of the ink is not greater than the adhesion of the anodized aluminum printed matter and the first print. The adhesion of the ink layer to the anodized aluminum.

6. When printing gold or silver ink on printed materials, the adhesion of gold and silver ink should be small, gold and silver ink should be placed on the final print. If there are words and patterns on gold and silver ink, the characters should be printed separately.

7. The superiority of the last printed yellow ink in four-color printing.

 The transparency of the yellow ink is good, and the final color printing is arranged to facilitate sufficient white light to enter the upper and lower ink layers to obtain bright and bright colors, which is beneficial to the print to achieve better color reproduction.

 Yellow ink has a faster drying performance and a larger printing area. Arranging the yellow ink in the last color printing can prevent the vitrification caused by the excessive drying speed of the yellow ink, and can fully utilize the characteristics of the large printing area and the rapid oxidation of the conjunctiva, covering the surface of other ink layers. Make the print have a certain degree of gloss. In short, in the specific printing process, according to the quality requirements of printed matter, according to the law of overprinting, the best printing color sequence can be flexibly selected, so as to avoid weakness, control color deviation, and print the most ideal printed matter.
