How to arrange the color sequence of color printing

  Arrange the color sequence from the overprint. Due to the deformation of the paper, such as the expansion of the objective existence of defects, we can put the overprint requirements of the printing of the main color arrangement in the adjacent two color group printing. Such as two-color machine, can be arranged in the same unit once the printing is completed, to avoid the paper due to the presence of paper and other issues caused by expansion. A large area of the field, you can arrange after India, to avoid the process of paper transfer rub dirty problems. In addition, monochrome machine in a "dry" after second overprint colors and multi-color machine is a process of "wet", so we should control the ink viscosity and the amount of ink. The poor quality of the paper, considering its whiteness, smoothness, fiber loose, poor ink absorption, easy to fall off the powder, you can print yellow ink primer, to make up for the defects of paper. When printing at night, due to the identification of the human eye, the low brightness of the color ink should not be arranged in the first color printing. The order of the ink is: white, yellow, orange, green, blue, red, blue and purple.

  As we know, the quality of Dalian color printing, copying process by many factors, such as the original color image halftoning, dot gain, color balance control, and in the middle of the prepress image production quality, directly determines the quality of printing products, although the business press can be correct for some inadequacies, but to the printing quality is basically incapable of action. In color printing, each machine has its own conditions of use and service life, for special conditions, the need to fine calculation to achieve. In color printing, the most important thing is the color printing effect. Because many are batch operations, any small errors will affect the final use of the results, so the operation must be careful and rigorous.
