What color is the most difficult to print among the colorful colors?

In our daily life, we have seen a lot of colorful and beautiful printed matter, which adds a lot of brilliant colors to our life. So what are the characteristics of a qualified printed matter? Printing is widely used, and there are many problems that need attention. Today I will focus on what kind of color is the most difficult to print, and what elements should be paid attention to when designing.

The first is gray balance. According to the theory and experience of production practice, the most difficult color to control in printed matter is gray balance. Gray balance is under a certain printing suitability, yellow, magenta and cyan three primary color plates are combined and overprinted according to a certain dot ratio from light to dark to obtain different brightness achromatic (white, light gray, gray, dark gray, black), that is There are many factors that affect the visual neutral gray color. The amount of ink used in printing, paper, full-page density, dot area, overprinting and screen line number will have an inextricable impact on the gray balance. It is the most test of the overprinting accuracy of the machine and the skill level of the operator.

The second is the superposition of several color dots, especially more than 70% dots. Specifically, dark brown, brown, dark green (flat screen, containing blue 70), dark blue, purple blue, etc. are difficult to print due to color differences, and it is difficult to find a balance on the printing machine.

The most difficult thing to print again is the four-color stacked blank characters. It is difficult to print too many multi-colors with extremely thin lines and extremely small characters, and it has extremely high requirements on the grippers of the machine. This is also a relatively common problem, so the prepress designer must check whether the black characters in the publication file, especially the small characters, are only on the black version and should not appear on other three-color versions before output. If it occurs, the quality of the printed product will be greatly reduced. When the RGB graphics are converted to CMYK graphics, the black text will definitely become four-color black. Unless otherwise specified, it must be dealt with.

In the final printing, things that are generally full-page, spot-color full-page or large in area, reverse white characters, the same logo, and the same color blocks are generally difficult to follow the color, and are prone to color difference, ghosting, smudges, and scratches. Phenomenon.

In short, qualified printed matter must meet:
1. Accurate overprinting;
2. Uniform ink color;
Three, the network is full;
Fourth, ink balance;
5. There are no printing faults in the printed matter, such as smudges, scratches, patterns, pastes, etc.;
6. Strictly faithful to the original manuscript. We must pursue high-quality prints to meet people's increasing aesthetic concepts.
