(Summary description)Printed matter adorns our lives and adds brilliant colors to our lives. So what are the characteristics of 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 experience of theory and production practice, the most difficult to control color of printed matter is gray balance. Gray balance means that the three primary color plates of yellow, magenta, and cyan are combined and overprinted from light to dark according to a certain dot ratio to obtain achromatic achromatic (white, light gray, gray, dark gray, black) with different brightness under a certain printability.

Printed matter adorns our lives and adds brilliant colors to our lives. So what are the characteristics of 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 experience of theory and production practice, the most difficult to control color of printed matter is gray balance. Gray balance means that the three primary color plates of yellow, magenta, and cyan are combined and overprinted from light to dark according to a certain dot ratio to obtain achromatic achromatic (white, light gray, gray, dark gray, black) with different brightness under a certain printability. Obtaining a visually neutral gray color has many factors that affect it. The amount of ink used in printing, paper, full-page density, dot area, overprinting, and number of screen lines will all have inexhaustible effects 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% of the dots. Specifically, dark brown, coffee, dark green (flat screen, containing blue 70), dark blue, purple blue, etc. are difficult to print because of the difference in color, and it is not easy to find a balance on the printing machine.

What is more difficult to print is the four-color stack of missing characters. Too many multi-color extremely fine lines and extremely small penetrating characters are difficult to print, which requires extremely high gripping teeth of the machine. This is also a relatively common problem, so the pre-press designer must check whether the black text in the publication file, especially the small print, is only on the black plate, and should not appear on the other three-color plates. If it appears, 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 larger area, reversed white characters, the same logo, and the same color block, generally difficult to follow the color, easy to produce color difference, ghosting, smearing, scratches Phenomenon.

In short, qualified printed matter must meet: 1. Accurate overprinting; 2. Uniform ink color; 3. Full dots; 4. Ink balance; 5. No printing faults, such as smearing, scratching, patterning, paste printing, etc.; 6. , Strictly loyal to the original manuscript. We must pursue high-quality printed materials to adapt to people's rising aesthetic concepts.
