1. Gray balance
According to theory and production practice, the most difficult color to control in 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 percentage of dot combination overprinting to obtain different brightness of achromatic (white, light gray, gray, dark gray, black), that is, to get a visual neutral gray color. There are many factors that affect it, the amount of ink used in printing, paper, full plate concentration, dot area, overprinting and the number of screen lines will have a myriad of effects on the gray balance, which is the most test of the overprinting accuracy of the machine and the skill level of the operator.
2. 4 color through the net and 3 color through the net
Do not print full plate color (recommended to use spot color printing)
3. People who don't know how to print design things that are the hardest to print
Color is one thing, too much very fine, very small word transparent white and so on.
4. "C=50, M=50, Y=50, K=50" large flat network
A little bit of inaccuracy will skew the color seriously
5. The text is four colors
6.There is a black base is also difficult to deal with
Black bottom can be used to achieve the effect of 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
Specifically, dark brown, brown, dark green (flat net, containing blue 70), dark blue, purple blue, etc. are not easy to find balance on the printing machine due to the color difference.So they're all hard to print colors.
8. Printing is generally full of things
Spot color full version or large area, anti-white characters, the same logo, and the same color block, it is generally difficult to follow the color, easy to produce color difference, ghost, dirty, scratched phenomenon.
9. Tiny words of gold and silver
Professionals said that small text is afraid of batch process dry plate, these should be controlled in place, the printing plate should be wiped clean, the ink viscosity is controlled at about 14, and pay attention to the dry plate.
In short, qualified prints must meet:
Accurate overprinting; The ink color is uniform; Full dot; Ink and wash balance; No printing faults, such as dirt, scratch, flower plate, paste plate, etc. Strictly true to the manuscript.
