How to arrange the color sequence of book printing?

Time: 2021-07-28 Hits: 187


In the printing of color books, how to arrange the order of color overprinting is an important topic that book printers in China need to study. The book printing companies must have a certain degree of artistic appreciation and the ability to master color changes. Incorrect color sequence arrangement may lead to color shift and color mixing in printed matter; reasonable color sequence arrangement will make the color of printed matter closer to the original, and even enhance a certain color atmosphere, making the level clear, clear, and true in color.


1. According to the content and characteristics of the original manuscript.

The arrangement of the color sequence must first consider the content and characteristics of the manuscript. When designing graphic layouts, editors often have chosen the tone of the layout color. This base tone represents the overall feeling of the entire tone and becomes the dominant color during printing. In terms of color properties, those based on red, orange, and yellow are called warm colors; those based on green and blue are called cool colors. Due to the hiding power of the ink, the warm tone is usually printed first in black and cyan, followed by magenta and yellow; the cold tone is mainly printed first in magenta and then cyan. Everyone hopes that the ripe watermelon flesh is red, and they don't want to see the purple or greenish color of the printed matter. The color sequence is different, the color cast effect is also different.

2. Consider the characteristics of the paper.

For poor-quality paper, considering its low whiteness, low smoothness, loose fibers, poor ink absorption, and easy powder and lint, you can print yellow ink as a primer first to make up for the above-mentioned defects of the paper. The lightness order of the ink is: white<yellow<orange<green<cyan<red<blue<purple.

3. The transparency of the ink.

With good transparency of the ink, after the two-color phase is overprinted, the color light of the lower ink layer can pass through the upper ink layer to achieve better subtractive color mixing and display the correct new color. If the yellow ink used is transparent yellow, the order of transparency of the four inks is: yellow>magenta>cyan>black. Generally speaking, the ink with poor transparency is printed first, and the ink with good transparency is printed later.

4. Whether it is conducive to overprinting.

Due to objective defects such as paper deformation and expansion, the main colors of printed products with higher overprint requirements can be arranged in two adjacent color groups for printing. For example, a two-color machine can be arranged in the same unit to complete printing at one time to avoid problems such as paper expansion and contraction caused by the existence of paper. It is very important to arrange the ink with high viscosity to print first, and the ink with low viscosity to print later, otherwise it will cause the error of reverse overprinting.

5. Consider process factors such as plate making.

When printing, the screen angles of adjacent two color groups differ by at least 30°, which is beneficial to prevent color aberration.

6. Consider the color sequence arrangement according to the cost.

The cheap black and cyan inks are printed first, and the expensive magenta and yellow inks are printed later.

Book color printing is a printing process that combines technology and art. When arranging the printing color sequence, proper consideration from an artistic point of view can make the printed matter more artistically appealing and better meet the needs of readers.
