In Jinan printing factory, what is the reason for the wrinkling of sample printing? That's what we want to understand. If the printed product is wrinkled, it will affect the overall effect. Only by understanding the reason of wrinkling in sample printing can we solve this problem better. Let's listen to the editor's summary of what he has learned.
In fact, the paper problem in the printing factory will lead to the wrinkling of printing products, because the moisture distribution of paper is different. If the moisture around the paper is larger than the middle part, the middle part will cause wrinkling. When the paper moisture content is too large, due to the pressure of deformation, and wrinkle products.
The reason of sample printing wrinkling is not only the problem of paper, but also the adjustment of the mechanical factors in the printing workshop. The product wrinkling caused by it is also very common. For example, the feeding pressure on the feeding plate is uneven, or the paper transfer is not appropriate, and the surface of the embossing roller is stained with some ink too thick, which will cause the sample printing to wrinkle.
