Die-cutting running gauge refers to the displacement of the position of the die-cutting part relative to the positioning gauge when the conditions change during the die-cutting process, and then the problem of inaccurate die-cutting indentation position occurs.
Common causes and solutions:
1. The die-cutting plate is not fixed firmly in the plate frame, and the die-cutting plate is displaced during the die-cutting process, which makes the die-cutting indentation position inaccurate; the solution is to re-calibrate and fix the die-cutting plate, and re-set the die-cutting rule.
2. The rules of die-cutting and printing are not aligned, and the position of the cardboard mouth is different , requires set printing with die cutting rules.
3. During the die-cutting process, the cardboard is deformed or stretched, which makes the alignment inaccurate during die-cutting; select reasonable materials and maintain a relatively stable ambient humidity to minimize the influence of the material itself on the die-cutting accuracy.
4. The paper feeding position is inconsistent during the die-cutting operation. The solution is to adjust the die-cutting paper feeding positioning rules to keep the paper feeding position consistent.
5. The position of the elastic die-cutting tape on the die-cutting plate is too close to the die-cutting knife when bonding, and there is no symmetrical sticking on both sides of the die-cutting knife, so that the elastic tape will generate lateral force when it is pressed, so that the The displacement of the paper will affect the positioning accuracy of die-cutting; the solution is to select a reasonable position for pasting. The most suitable distance between the elastic die-cutting rubber strip and the die-cutting knife is about 1-1.5 mm, and the pasting requires symmetrical pasting, which can play a role in It is better to prevent the effect of paper shifting at the moment of die cutting.
The above is to answer the main reasons and solutions for running gauge when flat die cutting and indentation. In the actual production process, there will be many other unpredictable reasons, and it is recommended to solve them according to the actual production situation.
