Prints adorned our lives and added a beautiful color to our lives. So what are the characteristics of qualified prints? The popularity of printing is very wide, and there are many problems to be aware of. Today, we 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 theory and production practice, the most difficult color to control is the gray balance. The gray balance is in a certain printing suitability, and the yellow, magenta and cyan primary color plates are combined with a certain dot ratio from shallow to deep to obtain different brightness achromatic (white, light gray, gray, dark gray, black), ie Obtaining the visual neutral gray color, affecting many factors, the amount of ink used for printing, paper, full plate density, dot area, overprinting and screen line number will have a huge impact on the gray balance. It is the most tested machine's overprinting accuracy and operator skill level.
Followed by the superposition of several color dots, especially more than 70% of the dots. Specifically, dark brown, brown, dark green (flat net, containing blue 70), dark blue, purple blue, etc., because of the difference in color, it is difficult to find a balance on a printing machine, so it is a color that is difficult to print.
It is harder to print in Shanghai again that the four-color stack is missing. Excessive multi-color polar lines are extremely difficult to print, and the machine's gripper is extremely demanding. This is also a relatively common problem, so the pre-press designer must check the black text in the publication file before the output, especially the small characters, whether it is only on the black version, but not on the other three-color version. 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. It must be handled unless otherwise specified.
In the final printing, the general version of the full version of the book, the full color or large area, anti-white characters, the same logo, and the same color block, generally difficult to color, easy to produce chromatic aberration, ghosting, dirty, scratched phenomenon.
In short, qualified prints must meet: first, accurate overprinting; second, uniform ink color; third, full dot; fourth, ink and water balance; five, printing without printing failure, such as dirty, scratched, flower plate, paste, etc.; Strictly loyal to the manuscript. We must pursue high-quality prints to adapt to the rising aesthetics of people.
