What is die cutting?

Mar. 17, 2023

"Die-cutting" refers to the cutting process of post-processing of printed matter, and die-cutting is a key step in the processing of color box packaging. We all run into problems along the way. To avoid problems, we always have solutions. Next, RX packaging will share with you several common color box die-cutting processes.

1.Low die-cutting precision: The reasons for low die-cutting precision include the die-cutting version itself and printed matter. The error of manual mold cutting is relatively large; the working environment of mold cutting indentation and printing process will cause paper deformation, resulting in inaccurate position of mold cutting indentation, especially after coating, paper deformation is more serious, which affects mold cutting accuracy.

2. Die-cutting indentation "burst line" and "dark line": due to improper selection of die-cutting plate and indentation steel wire. Improper adjustment of die-cutting pressure. Poor paper quality. The direction of paper fiber is inconsistent with the direction of die-cutting knife. Low water content leads to decreased flexibility and other reasons.

3. Indentation line movement. Dissatisfaction: Under the action of die-cutting pressure, the indentation wire is twisted, which will cause the indentation line to move; insufficient die-cutting pressure will cause the indentation line to be dissatisfied.

4. Die-cut fluffing and dusting: When the die-cutting is combined, the rubber strips and indented steel wires on the die-cutting plate generate tension on the paper, and the paper is broken by the tension when it is not completely cut through. Frizz appeared.

5. Die-cutting "paste version": The density or hardness of the sponge strip pasted around the die-cutting knife is too small, and the resilience is insufficient; the die-cutting blade is not sharp, and the paper is too thick, resulting in the sticking of the knife during clamping or die-cutting. Can result in die-cut "fuzzy".

The above are 5 problems that are often encountered in the die-cutting of color box packaging.
