What Are The Reasons For The Misalignment During Die Cutting?

- May 10, 2019-

1. The affixing of the paper and the backing paper is not allowed to cause the positioning error of the die cutting.
 
2. Poor machine misalignment caused by poor machine positioning.
 
Let me say that the first type of paper and paper are not allowed to cause the positioning error of die cutting.
 
If the two layers of paperboard on the printed surface and the non-printed surface are inaccurate, the non-printed paper will protrude from the paper edge of the printing surface, which will inevitably cause the die-cut positioning error of the paperboard.
 
Because it is almost inevitable that there will be inaccurate stickers in the process of posting.
 
Approach:
 
1. In order to prevent the convex image from appearing on the non-printing surface of the plaque, it is necessary to add the trimming edge of the printed semi-finished product and the front paper edge to the trimming edge of 3mm-6mm according to the characteristics of the product. margin.
 
2. The paper edge of the non-printing surface is appropriately shrunk by a few millimeters for collapsing, which can effectively prevent the convex image from appearing on the non-printing surface, and ensure accurate die cutting of the product.
 
Let's talk about the misalignment of the die cutting caused by the bad machine.
 
If some parts of the die-cutting machine are worn or loose, it is also easy to cause the positioning of the cardboard die-cutting.
 
This requires that the daily maintenance and repair should be done according to the manual. Before the production, the machine should be carefully observed and inspected. Corresponding measures should be taken to deal with the existing defects to ensure accurate die cutting.
