Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a corrugated board printing device with clear printing. Background Art

[0002] Corrugated paperboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products. When using corrugated paper for packaging, or before packaging, a large amount of printing is required on the corrugated paper to improve recognition.

[0003] During the printing process, a roller is used to roll directly on the corrugated paper, so that the print on the roller is printed on the corrugated paper. During the long-term use of the roller, the print will be worn and the clarity of the print will be reduced. At the same time, during the printing process, the adhesion of the coating on the print is unstable, which is more or less likely to cause the pattern on the corrugated paper to be blurred, or the texture is too heavy to be air-dried, so that the pattern on the corrugated paper adheres to other corrugated paper surfaces, reducing practicality.
