The color printing tips you cannot miss

What are the precautions for full color book printing in China? And for the color printing in China, what is the standard for color books? The following summarizes a few book printing tips of color printing for your book printing in China.
1.The most difficult color to control in the printing process of Chinese books is gray balance. Gray balance means that the three primary colors of yellow, magenta, and cyan are combined and overprinted from light to dark according to a certain dot ratio to obtain achromatic achromatism with different brightness under a certain printability, that is, a visually neutral gray color is obtained. In book printing China, there are many factors that affect the gray balance in color printing. The amount of ink used in printing, paper, full-page density, dot area, overprinting, and screen lines will all have inextricable effects on the gray balance. This is the most test of the overprinting accuracy of the machine and the skill level of the Chinese printer.
2.Four-color printing is generally composed of CMYK colors. If the four colors are all large flat screens with an average of 50, the color cast will be serious if there is a little inaccuracy. If the color printing of CMYK used for text which makes it difficult in high-quality book printing in China. This is also a relatively common problem, we should do a comprehensive inspection of the information provided by the customer before printing. 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.
3.It takes more time to print a full-page black color, and it is also a bit difficult. If the customer is in a hurry to get the goods, the book printing will be difficult to dry, which will cause the front and back sides to rub, and scratches will cause a not beautiful appearance.
4.For color printing, the superposition of several color dots, especially more than 70% dots. Specifically, dark brown, coffee, dark green, 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. Color printing is a matter in the hardcover book printing process. As per my friend, a professional book printer China, he wrote an article about “Colour printing: matters to be noted”. Different color settings will have different effects during hardcover book printing in China.
5.The spot color is full or large in size, with reversed white characters, the same logo, and the same color block. Generally, it is difficult to follow the color, and it is easy to cause color differences, smears, and scratches.
