印刷断纸多数是印刷批量较大的产品，印刷速度快，印刷过程中纸张承受的张力比较大，而且印刷后还要进行折页，所以，在整个走纸过程中需要保持一定的纸面张力，以适应轮转印刷的需要。印刷过程中影响纸面张力的因素较多，印刷速度越快，张力就越大，断纸的发生几率就越高。今天，
济南彩色设计印刷厂家就给大家介绍一下导致印刷出现断纸现象的原因。
Most of the printing paper breaks are products with large printing batches. The printing speed is fast. The paper bears relatively large tension during the printing process, and the folding is required after printing. Therefore, it is necessary to maintain a certain paper tension during the whole paper feeding process to meet the needs of rotary printing. There are many factors that affect the paper tension in the printing process. The faster the printing speed, the greater the tension and the higher the probability of paper breakage. Today, Jinan Color Design and Printing Factory will introduce to you the causes of paper breakage in printing.
1、由于不同原因，迅速停止供纸，打纸器就会将纸袋打断，导致印刷出现断纸的现象。
1. For different reasons, if the paper supply is stopped quickly, the paper feeder will break the paper bag, resulting in paper breakage in printing.
2、长时间开机，墨水污垢沉积在导纸辊上，导致出现断纸现象。
2. When the machine is started for a long time, ink dirt is deposited on the paper guide roller, resulting in paper breakage.
3、速度变化不正常，设备运行过程中速度的不正常变化有可能导致印刷工作出现故障。
3. Abnormal speed change. Abnormal speed change during equipment operation may lead to printing failure.
4、纸卷本身存在问题，比如纸张质量不合格或者存放不当，导致纸卷中心偏移，出现断纸现象。一般纸卷偏心超过5毫米便不合格，偏心则易引起断裂。
4. There are problems with the paper roll itself, such as unqualified paper quality or improper storage, resulting in the deviation of the paper roll center and paper breakage. Generally, if the eccentricity of the paper roll exceeds 5mm, it is unqualified, and the eccentricity is easy to cause fracture.
5、张力太大，纸张的张力有限，增加张力时应避免极限张力，而且在印刷设备高速运转的情况下，很小的变化也会出现较大的张力，导致断纸。
5. If the tension is too large, the tension of the paper is limited. When increasing the tension, the limit tension should be avoided. In addition, when the printing equipment is running at high speed, a small change will also cause a large tension, resulting in paper breakage.
In addition, if there are edge cracks and bruises during printing, if they are found and handled in time, such failures will not have a great impact on printing. For more relevant color design and printing matters, please visit our website https://www.sdhzyw.com Ask!
