With the gradual development of the express industry, the use of boxes is not simple, people's requirements for custom Notebook Printing pay more attention to the beauty and box display brand elements, comprehensive consideration and excellent quality is also essential. Let the custom Notebook Printing manufacturer analyze the main factors of box quality.

1. Glue quality: Adhesives are needed in the production of packaging boxes, which can increase the hardness and bearing capacity of cartons and are not easy to deform. Needless to say, the adhesive force is better.

2. Cardboard quality: Cardboard quality is determined by the quality of the base paper, so if you want to use high-quality packaging boxes, you must use high-quality base paper.

3. Packaging box production environment: As we all know, packaging boxes are prone to moisture, which will affect the compressive strength of the carton. Therefore, the production environment temperature and air humidity are generally low requirements.

4. Paper matching skills: To improve the compression ability of the packaging box, we must first improve the compressive strength of the core paper.

5. Poor smoothness of cardboard: the bottom is exposed when printing, resulting in white holes. In order to solve this problem, the common method is to increase the printing pressure. But this will have side effects, on the one hand will cause deformation of the network, on the other hand will destroy the corrugated structure.

6. On the carton production line, when a single knife trims the edge, the knife cuts from top to bottom, often resulting in uneven paper edges on the cardboard surface; When printing the full plate, the edge cannot be printed and the bottom is exposed. While pressure can alleviate this phenomenon, it cannot eliminate it.

7. When four-color layers are printed, paste plates often appear to connect the dots of printed matter together.

8. In large field printing and color overlapping printing, use color inks mixed with two or more inks for printing and grooving. Line pressing. Easy to drag color when die cutting.
