印刷斷紙多數是印刷批量較大的產品，印刷速度快，印刷過程中紙張承受的張力比較大，而且印刷后還要進行折頁，所以，在整個走紙過程中需要保持一定的紙面張力，以適應輪轉印刷的需要。印刷過程中影響紙面張力的因素較多，印刷速度越快，張力就越大，斷紙的發生幾率就越高。今天，
濟南彩色設計印刷廠家就給大家介紹一下導致印刷出現斷紙現象的原因。
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，迅速停止供紙，打紙器就會將紙袋打斷，導致印刷出現斷紙的現象。
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、長時間開機，墨水污垢沉積在導紙輥上，導致出現斷紙現象。
2. When the machine is started for a long time, ink dirt is deposited on the paper guide roller, resulting in paper breakage.
3、速度變化不正常，設備運行過程中速度的不正常變化有可能導致印刷工作出現故障。
3. Abnormal speed change. Abnormal speed change during equipment operation may lead to printing failure.
4、紙卷本身存在問題，比如紙張質量不合格或者存放不當，導致紙卷中心偏移，出現斷紙現象。一般紙卷偏心超過5毫米便不合格，偏心則易引起斷裂。
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、張力太大，紙張的張力有限，增加張力時應避免極限張力，而且在印刷設備高速運轉的情況下，很小的變化也會出現較大的張力，導致斷紙。
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 http://www.zhouyingzi.cn Ask!
