The printing factory often receives some color page printing requirements or direct folding printing requirements. In the actual production process, there are two kinds of folding methods: one is thin paper, which is folded directly with the folding machine, and the other is 157 g matte copper paper, with the previous indentation.

当您打印的纸张超过157克时，在折页机前面的折痕可以使折页更容易，使折页打印更平整，更美观。

When you print more than 157G of paper, the crease in front of the folding machine can make the folding easier and make the folding printing more flat and beautiful.

印后在压痕或折页印后出现的图像裂缝可能是由于纸张干燥造成的，而纸张量越高越容易出现这种故障。因此，为避免裂缝，应使纸张保持适当的湿度，不要太干。

The image cracks after indentation or folding may be caused by the paper drying, and the higher the paper volume, the more prone to this fault. Therefore, in order to avoid cracks, the paper should be kept appropriate humidity, not too dry.

此外，折页纸沿丝线方向折页，还可以避免折痕断裂现象。如果是加工企业的济南画册印刷，纸张的方向应平行于终产品画册的书脊。当然，在印版上覆膜也可以避免印版合页裂缝。

In addition, folding paper along the direction of the silk line, can also avoid folding fracture.
