Printed matter enriches our life and brings convenience to our life. However, in Luxury packaging boxes printing, some colors are very difficult to print and difficult to control.

1, gray balance, according to theory and production practice experience, the most difficult color to control print is gray balance. Gray balance is under a certain printability, yellow, magenta, green three primary color plate from light to deep according to a certain dot ratio combination overprint to obtain different brightness color, that is, to get the visual neutral gray color. There are many factors that affect it, and the amount of ink used in printing, paper, full plate concentration, dot area, overprint and the number of screen lines will have an inextricably influence on the gray balance.

2, 4 color over the net and 3 color over the net, full color do not print.

3. People who don't know how to print design things that are the hardest to print. Color is on the one hand, too many multi-color pole line thin, very small word transparent white and so on.

4, C=50M=50Y=50K=50 large flat network, a little inaccurate color is serious.

5, the text is four-color, that is, there are words in the four colors of cmyk, especially small words, it is difficult to put on, and the machine's paper teeth are extremely demanding. Therefore, the prepress designer must check the black text in the publication file before output, especially the small print, is not only on the black edition, and should not appear on the other three-color edition. If it appears, the quality of the printed product will be greatly reduced, and when the RGB graphics are converted to CMYK graphics, the black text will definitely become four-color black.

6, the black base is not good to deal with, the black bottom in order to achieve the effect can use extra black ink or printing twice, it is not difficult to print, more time-consuming.

7, several color network superposition, especially more than 70% of the network. For example, dark brown, brown, dark green (flat net, containing blue 70), dark blue, purple blue, etc. are difficult to find balance on the printing machine due to the color difference, so they are difficult to print colors.
