Corrugated board: note in printing

In actual production, there are often cases where the compressive strength of the carton is degraded due to improper design and printing methods. Therefore, the following problems should be noted in the design and printing of the corrugated box.

1, to avoid full version printing: corrugated box full version or around the printing of graphics, in addition to the embossing roller corrugated board pressure, the ink also has a wetting effect on the paper surface, which will make the corrugated box compressive strength reduce. Therefore, the simpler the printing of corrugated cartons is, the better the artwork should be. It is best to avoid printing artwork on the entire surface of the box as much as possible.

2. Avoid strips (the same direction as corrugated cardboard machines). Printing: Some decorators are lacking the printing process knowledge. The design of the carton printing pattern has some horizontal gradient lines. When printing, the printing pressure crushes the corrugation. Stress concentration occurs in this area of ​​the carton and is therefore the most easily broken.

3, ink color should be eye-catching: due to the color of the corrugated cardboard itself is quite dark, so when choosing the color of the printing must take into account the use of color saturation, strong coloring ink (such as large red), or printed out of the color There is a big gap with the desired color.

4. Minimize the number of overprints: The more times of overprinting, the more severe the compressive strength of corrugated boxes declines.

5, to avoid the printing of small text: as a corrugated box printing, considering the effect of promotional products, should determine the size of the font. Words with a size of 2cm or less are almost indistinguishable when the distance is 5m or more. This loses the significance of publicity and promotion.

6, as much as possible to reduce the printing pressure: In order to ensure the quality of carton printing, and reduce the impact on the strength of corrugated boxes, the printing pressure should be as small as possible, the ink used as fast as possible use of ink. Secondly, the printing surface and the horizontal indentation line should be maintained at a distance of 15mm or more, because the corrugated cardboard cannot be fully accepted by the pressure of the presser platen of the binding machine, otherwise the printing effect will be affected.
