The printing effect and performance of coated white paperboard are closely related to the coating formulation. Whether the printed image is clear and vivid, whether the color is vivid, and the printing strength, ink absorption, ink absorption, ink absorption speed, printing gloss of the coating are relatively large. relationship. The printing surface strength of coated paperboard has a large and direct impact on the quality of coated paperboard and is the key to coated paperboard printing. The low strength of the coated paperboard printing surface can cause the printed matter to fall off the powder and cause a paste. Paste is mainly caused by several aspects: (1) The distribution of pigment particles in the coating is poor and the amount of the adhesive is insufficient, or the strength of the surface layer of the base paper is low, so that the surface strength of the coating is insufficient. (2) Wet napping, the effect of wet repulsion. (3) In the post-sequence section, if the rewinding paper is cut, the round knife is not sharp, and the paper edge is raised. (4) The surface of the coated paperboard has poor fiber bonding strength and dust on the paper surface and paper bottom. Paper surface strength includes dry and wet napping strength. The coarseness of the coating particles and the insufficient amount of the adhesive have led to the recognition of the dry pulling strength of the powder and the hair loss. This problem is more convenient to solve. According to the printing principle and printing process, offset printing is based on the oil and water resistance of the printing plate, the blank part is absorbent and oil resistant, and the water and oil are incompatible with each other. The ink balance is the basis of printing, the size of the water, Directly affect the darkness of the printed matter. The so-called wet repulsion is that when printing offset printing, the paper pattern is partially printed with ink and the blank portion is printed with a water film of 0.2-0.3 Lm thick. Only when the color is printed, the water film is absorbed by the paper surface, and these blank portions are absorbed. In order to accept the ink well, otherwise the water film left on the paper will repel the ink, so that the next color will not be colored. Especially in the high-speed printing of four-color and five-color machines, the paper will be wetted many times, which will affect the ink. Transfer. The action of water softens the surface of the paper, and the ink changes the surface of the paper due to stickiness and moisture. When printing, the ink pulls out the particles on the surface of the paper, which is also called wet pulling. Wet repulsion occurs simultaneously with wet plucking and is difficult to distinguish because the results of their performance cause the printed pattern to be white spots, as the wet plucking and wet repellency are affected by the time interval between the wetting water and the printing. In multi-color offset printing, the time for the two colors to overlap depends on the printing speed and the distance between the printing units, and the printing effect has a great relationship with the value of ink absorption, surface water absorption, paint adhesive, water resistance and the like. Surface water absorption has a large effect on wet repulsion, and the coated paper is printed on a multicolor printer. According to the printing requirements, the amount of dampening fluid is first determined according to the test print. For example, the water absorption is large, the surface of the printing blank is too small, the blank portion is dirty, and the image is partially blurred. If the water absorption is small, the surface of the printing blank is too moist to emulsify the ink, causing the ink to become light and dim. If the water absorption is too large, it may easily cause the deformation of the cardboard, resulting in inaccurate overprinting and serious quality problems. If the cardboard absorbs unevenly, it will cause uneven printing color. Therefore, the size of the water absorption on the surface of the paperboard directly affects the depth of the ink of the printed matter, so it is necessary to control the water absorption of the surface of the coated paper within a reasonable range.
