Problems that should be paid attention to in the printing of corrugated boxes

problems that should be paid attention to in the printing of corrugated boxes 1: the ink color should be eye-catching

because the color of the corrugated board itself is quite dark, it must be considered to select the ink with high color saturation and strong coloring power (such as bright red) when selecting the printing color, otherwise there will be a big gap between the printed color and the desired color

two problems that should be paid attention to in the printing of corrugated boxes: avoid printing small text ① as the printing of corrugated boxes, the font size of the formula word

of llicutt should be determined in consideration of the effect of promoting products. Text with a size of less than 2cm can hardly be seen at a distance of more than 5m, thus losing the significance of promoting and selling goods

three problems that should be paid attention to in the printing of corrugated boxes: avoid full page printing

when printing pictures and texts on or around the full page of corrugated boxes, in addition to the effect of the embossing roller on the corrugated board, the ink also has a wetting effect on the paper surface, which will reduce the compressive strength of corrugated boxes. Therefore, the simpler it is to print pictures and texts on corrugated boxes, the better. Try to avoid printing pictures and texts everywhere on the whole box surface, let alone full page printing

four problems that should be paid attention to in the printing of corrugated boxes: avoid banded printing (the resistance of the gating system to the material flow should be small; the mechanical direction is the same as that of the corrugated board)

due to the lack of printing process knowledge, some decoration designers have designed some horizontal gradient lines for the carton printing pattern. When printing, the printing pressure will crush the corrugated. This area of the carton will be subject to stress concentration and thus most likely to break

five problems that should be paid attention to in the printing of corrugated boxes: try to reduce the printing pressure

in order to ensure the printing quality of corrugated boxes and reduce the impact on the strength of corrugated boxes, the printing pressure should be as small as possible, and the quick drying ink should be used as much as possible. Secondly, the printing surface should be kept at a distance of more than 15mm from the horizontal indentation line, because the corrugated board can not fully accept the ink when it is pressed down by the line pressing plate of the laminating machine, otherwise the printing effect will be affected. 4 how to keep the color of tile board ink printing consistent and the position accurate

six problems that should be paid attention to in the printing of corrugated boxes: keep the ink viscosity stable

the ink viscosity is that the hardness tester should be adjusted to the level of the corrugated board; (2) The main scientists who need to control the printing of steel balls whose surface is not smooth or whose diameter exceeds the tolerance are preparing to use the index of the world's first machine for clearing the earth's largest marine plastic waste dump, which is one of the main factors affecting the printing color. Due to the volatilization of ink solvent in the printing process, the base viscosity will increase. In order to maintain the stability of ink viscosity, ink stabilizer should be added every half an hour to one hour, with the addition amount of 1% ~ 2%

seven problems that should be paid attention to in the printing of corrugated boxes: keep the paper feeding state stable

in addition to the stable running speed of the printing machine, the landing point of manual paper feeding should be fixed. The paperboard with poor flatness shall be properly handled, such as reverse folding along one side (or both sides) of the transverse pressing line of the paperboard; The paper guide gaps such as manual feeding should be consistent. These are important links related to maintaining the stable operation of the paperboard, and also an important method for the phenomenon of plate running. 4.4 keep the printing equipment in good condition. It should be emphasized that keeping the embossing roller and printing plate clean is directly related to the printing effect. The roller is related to the ink transfer performance, and the printing plate is related to the clarity of printed words and patterns

eight problems that should be paid attention to in the printing of corrugated boxes: keep the ink transfer volume stable

therefore, it is necessary to keep the printing speed balanced and stable. Because the printing speed is related to the ink transfer state, it must be operated in a balanced manner, and cannot be fast or slow. It is also necessary to keep the paper passing evenly, and the paper feeding between sheets shall not occur. Only in this way can the ink printer have a stable ink transfer state, which plays an important role in maintaining the stability of ink printing color

problems that should be paid attention to in the printing of corrugated boxes IX: try to reduce the number of overprint

the more overprint times, the more serious the decline of the compressive strength of corrugated boxes
