The paper appears to drop hair, de powder fault, generally due to the poor quality of paper products caused by. In addition to the suggestion that the paper manufacturer should improve the quality of the products as soon as possible and require the return of the products, the operator can also take corresponding remedial measures according to the specific conditions of the printed paper

一、纸张由于原料及制造工艺等原因，在印刷过程中可能会脱粉、掉毛，堆积在橡皮布的表面上，从而影响网点正确传递，严重时每印1千张左右就得擦洗橡皮布，否则橡皮布上粘满了脱粉掉毛，印刷出来的产品光泽度明显下降。有条件的情况下在纸张表面上套印一道白墨和清水，一般应多擦洗橡皮布。

1、 Due to the reasons of raw materials and manufacturing process, paper may be dusted and fluffy in the printing process, which will accumulate on the surface of blanket, thus affecting the correct transmission of dot. In serious cases, the blanket will have to be scrubbed for every 1000 sheets printed, otherwise the blanket will be covered with dusting and fluffy, and the gloss of the product will be significantly reduced. If possible, overprint a white ink and water on the surface of the paper. Generally, scrub the blanket.

二、适当调节好所用油墨的粘度，在油墨中加入适量的撒粘剂和稀释剂，降低油墨中的粘度，以此改善油墨的粘结性对纸张的影响。因为油墨粘性过大也容易使纸张掉毛脱粉。

2、 Properly adjust the viscosity of the used ink, add appropriate amount of dispersant and diluent in the ink to reduce the viscosity of the ink, so as to improve the effect of the adhesiveness of the ink on the paper. Because the ink viscosity is too large, it is also easy to make the paper off hairy powder.

三、调节印刷压力，使橡皮滚筒与压印滚筒之间的压印力适当减小。或者选择合适的印刷速度，以适当降低速度为好。这样在压印之后，橡皮布与纸张之间的剥离拉力就可以减小。

3、 Adjust the printing pressure to reduce the printing force between the rubber roller and the impression roller. Or choose the right printing speed, in order to reduce the speed. In this way, after imprinting, the stripping force between blanket and paper can be reduced.

四、对容易出现掉毛脱粉的纸张，如胶版纸、凸版纸、书写纸等，在太原宣传单印刷前一定要进行晾纸处理，将纸张表面上的纸屑、纸粉、纸灰和尘土、破烂纸等干净。

4、 The paper prone to exfoliation, such as offset paper, relief paper, writing paper, etc., must be air dried before Taiyuan flyer printing, and the paper scraps, paper powder, paper ash and dust, ragged paper, etc. on the surface of the paper must be removed.

综上所述，印刷纸张产生脱粉、掉毛的原因除因纸张的表面强度低而引起以外，填料与胶料选用的不适当，压光不实也是产生的原因。

To sum up, besides the low surface strength of the paper, the improper selection of fillers and binders, and poor calendering are also the reasons for the de dusting and hair loss of printing paper.
