1. The weight distribution of carbonless paper rolls is uneven. This problem is not related to the printing Waybill Printing For Express Factory. It is mainly because when the raw paper is processed, due to the influence of the paper machine, the thickness of the paper roll is not only fluctuating, but also the weight of both sides. big change. Even if the paper roll after cutting has more or less this problem, is there a way to solve this problem? In fact, the main reason is to control the size of the slitting when cutting. For example, the commonly used computer printing paper 241mm specification, the smaller the width dimension, the smaller the negative impact of the problem.

2. It is well known that the uneven water content is also relatively large for Mailing Waybill. If the water content of the storage paper roll is gradually averaged over a period of time, the water content of the paper product just produced is relatively uneven, if no carbon paper The packaging of the roll has a broken place. The outside air will affect the moisture content of the paper roll, which will eventually cause the problem of deformation and expansion of the paper roll due to different water content. The final result is the elastic side.

3. When the large roll of base paper is cut into small rolls of base paper, it is easy to produce the problem of elastic edges, and the small slitting equipment has more problems. Generally, this small slitter is not expensive because of the price. Therefore, the equipment standards are not very high, and there is no high precision of the large slitter winding. The solution is to increase the printing tension and maintain a smooth processing quality for problematic carbonless paper rolls when printing on computer paper. Remember not to blindly increase and maintain high-speed printing, otherwise paper breaks may occur. phenomenon. In addition, the loose side of the paper roll can be effectively improved by rewinding the problem paper roll once.
