2. The color sequence is not properly arranged. After the color group, the ink viscosity is greater than the pre-color group, and the post-color group inverts the ink in the pre-color group to cause accumulation, and severe color can also cause cross-coloring. By adjusting the color sequence and adjusting the viscosity of the ink, the viscosity of the ink in the back color group is slightly smaller than the viscosity of the ink in the front color group.

3 blanket surface crystallization, too smooth. The experimental comparison shows that the smooth surface of the blanket has a much greater adsorption capacity for the paper-bound impurities than the rougher blanket. Solution: Thoroughly clean the blanket to return to a fluffy surface, or choose a blanket with a slightly rougher surface for better results.
4. Ink emulsification is excessive. After the ink is emulsified, the pigment will separate from the floating state and remain on the blanket to cause a “stack of rubber†or to remain on the plate to cause “stackingâ€. It can be seen that the ink on the ink roller is sticky, and the ink is dull. By cleaning the ink roller, the viscosity of the ink can be appropriately reduced, and the ink balance can be adjusted and controlled to be solved.
5. The paper surface coating is not sticky and the paper powder is too much. The coating on the surface of the paper is unevenly coated or the sizing is insufficient. Under strong light, it can be clearly seen that the surface of the paper is rough or there are many paddles. For this kind of situation caused by the "rubber eraser" failure, in addition to adding the right amount of additives, but also without affecting the quality of the print under the appropriate circumstances to reduce the printing pressure, and reduce the speed during the printing process, in order to reduce the paper stripping to be solve. If conditions permit, the white material can be passed through the empty roller to remove paper and confetti on the surface of the paper. If the product allows, it will be better if the light paddle is passed through once.

6. One of the main reasons for stacking rubber is due to the high viscosity of the ink, which causes the fibers and paper powder on the surface of the paper to stick and pile up on the blanket. Solution: You can put appropriate additives or viscosity reducer in the ink to reduce the viscosity of the ink. The additive amount should be controlled so as not to affect the drying performance and gloss of the ink.
First, the print head control
The ink dots are sprayed onto the paper through nozzles. In general, the nozzles and the print heads are made together. Therefore, the technology of the print head itself is very important, and the left and right print heads are the inkjet technology and printer cantilever gears and transmissions. The precision of the belt.
Second, the resolution
For black-and-white laser printers, resolution may be the key to print quality, but for color printers, color gamut and resolution are equally important. The DPI resolution is written by DotPerInch, which means that the number of dots can be printed in one inch width. In the case of black and white laser printers, the higher the resolution, the finer the resolution and the color scale points are, and the better the print quality is. But for color printers, the resolution refers to how many ink dots can be printed in a width of 1 inch, regardless of whether the ink dots overlap.

Fourth, color conversion
In nature, all colors are composed of different wavelengths of light. When light passes through the prism, the spectra produced by the various wavelengths of light can be seen. "Spectral" can be said to be a natural phenomenon of continuous color mixing, but we can use it to define the color change and further manage the desired color. On television, movies, computers, and screens, we are dealing with color changes using the "add color method." It contains the main three colors: red, green, and blue (Red, Green, Blue), which is also known as the three primary colors (R, G, B). All colors can be overlapped by these 3 different colors of light. But for prints, the human eye uses reflected light to determine the difference in color. When you see a red paper, because the light is shining on the paper, the red light in the spectrum reflects, so you know it is red. of. Therefore, in the printed matter, the color must be defined using the "subtractive method", which is the so-called three-color model of C, M, Y (cyan Cyan, magenta Magenta, yellow Yellow). For colored light, red, green and blue can be mixed white light, but when using watercolor or paint to paint, they will find that the color will be deeper and deeper, red, green and blue are not white.
