What is the main reason for the pasting of the four color machine when printing

The ink is large, the water is less, and the ink is emulsified.

Hello, dear, there are many kinds of problems with four-color offset printing machines, and there are many ways to solve them. Here are some of the problems you may encounter and how to fix them:- Color deviation in print:

This can be due to factors such as ink disc thickness, dot adjustment, color correction, or color space. Color deviations can be corrected by adjusting these parameters, or a color management system can be used to guarantee correct color output. - Poor quality of the print:

This can be caused by factors such as worn plates, incorrect ink, insufficient printing pressure, or the use of low-quality materials. Try changing the printing plate, replacing high-quality ink, adjusting the printing pressure, or using high-quality printing materials to improve the print quality. - Poor ink flow:

This can be caused by factors such as the ink tray being too dry, the ink tray being over-cleaned, or improper storage by the company. You can try replacing the ink disc with a new one, humidifying it, or injecting a detergent into the ink disc to solve this problem. - Stretched or twisted prints:

This can be caused by factors such as poor force adjustment of the press, poor web tension control, or incorrect materials. You can try to adjust the adjustment and tension control of the press, change the appropriate materials, or perform maintenance and care on the press. If the above methods do not solve the problem, it is recommended that you ask a professional to repair it or consult the technical support department of the corresponding manufacturer.

Summary. Hello, four-color printing is the most basic printing method in brochure printing, and its requirements are very high. For professional printers or enterprises, the mastery and understanding of printing color is a very important basic skill, so what are the rules for color collocation in printing?

Pure color can be printed with one primary color or two primary colors, and the size of the chroma depends on the number of primary color inks, the more the quantity, the higher the saturation, such as the light solid color series and the strong solid color series and the color of the two-color series on pages 28-30. The hue obtained by printing with two primary colors depends on the relative ratio of the two primary colors, and the hue of the process color is biased towards the color with a large proportion, as shown in the color ring on pages 10 and 13: adding a third primary color on the basis of the solid color of the two primary colors will make the chroma of the process color lower, and the brightness will be reduced accordingly, while the hue of the process color is basically unchanged, because the mixing of the three primary colors will form a non-color, and its effect is similar to the effect of printing with less color in the same proportion and a certain amount of black ink, Such as light and dark series and three-color printing colors.

Light green has been printed well, change dark green such as printing.

Is it good to print. It's not good, saturate the ink a little.

What does it mean to be saturated with ink.

The ink with large concentration is used less in printing, and the ink color is better; Inks with small concentration are used more in printing, and the ink color is light.

Yes. Photocopying only.

Is the color of the copy accurate?

The color is not so uniform, and it is generally fine.
