Printed matter embellishes our life and adds a gorgeous color to our life. So what are the characteristics of qualified printed matter? Printing is very popular, and there are many problems that need to be paid attention to. 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 color to control is gray balance. Gray balance is that under a certain printability, yellow, magenta, and cyan primary color plates are overprinted according to a certain dot ratio from light to deep to obtain achromatic (white, light gray, gray, dark gray, black) with different brightness, that is to say, the color of neutral gray on the vision is obtained. There are many factors affecting the color, such as the amount of ink used by printing brush, paper, full plate concentration, dot area, overprint and screen line number Gray balance has a myriad of effects, which is the most test of the overprint accuracy of the machine and the skill level of the operator. The second is the superposition of several color dots, especially more than 70% dot. To be specific, dark brown, brown, dark green (flat screen, containing blue 70), dark blue, purple blue and other colors are difficult to print because of the color difference, which makes it difficult to find a balance on the printing machine. Again, it is more difficult to print the missing words in four colors. It is difficult to print too many multi-color fine lines and very small characters, which requires high requirements for the paper teeth of the machine. This is also a common problem, so the pre press designer must check whether the black text, especially the small characters, is only found on the black version, but should not appear on other three color editions. If it appears, the quality of the printed product will be greatly reduced. When RGB graphics are converted to CMYK graphics, the black text will definitely become four color black. Unless otherwise specified, it must be dealt with. Finally, when printing something that is generally full of the plate, the spot color is full or the area is large, the reverse white words, the same logo, and the same color block are generally difficult to follow the color, and it is easy to produce color difference, ghost shadow, rubbing dirty and scratch. In a word, qualified printed matter must meet the following requirements: 1. Accurate overprint; 2. Uniform ink color; 3. Full dot; 4. Ink balance; 5. No printing failure, such as rubbing dirt, scratches, stencil, paste, etc.; 6. Strict adherence to the original. We must pursue high-quality printed matter to adapt to people's increasing aesthetic concept.
