包装印刷中容易遇见的几个小问题!

  包装印刷看似简单,但对尺寸、颜色都需要有一个非常严格的把关,才能保证客户收到效果满意的包装产品.

  Package printing seems simple, but we need to have a very strict check on size and color to ensure that customers receive satisfactory packaging products

  针对于下面几种比较常见的包装盒印刷失误,景兴做了一个归纳:

  In view of the following common printing errors of packing boxes, Jingxing made a summary:

电竞平台  问题1,尺寸不对,出现移位现象;

  Problem 1: the size is not correct and there is displacement;

  尺寸出现问题,一般多由于开槽刀的位置出现偏差,或者机器在运作过程中出现小幅度移位,还有可能就是纸张不规则、出现弯曲等现象造成包装盒尺寸出现偏差;

  The size problem is usually caused by the deviation of the slotting knife position, or the small displacement of the machine in the operation process, or the paper irregularity, bending and other phenomena, resulting in the deviation of the final packaging box size;

  解决方法:可以调整开槽刀的位置打样调试一下,如果是纸张弯曲造成的,可以将纸张压平处理,一般纸张仓库需要保障一定的湿度,这样更有利于纸张的储存,纸张在湿度明显的环境下,接触空气的部分会吸水而未接触空气的部分因为水分蒸发而造成纸张的弯曲;

  Solution: you can adjust the position of the slotting knife for proofing and debugging. If it is caused by the bending of paper, you can flatten the paper. Generally, the paper warehouse needs to guarantee a certain humidity, which is more conducive to the storage of paper. Under the environment with obvious humidity, the part contacting the air will absorb water and the part not contacting the air will cause the bending of paper due to the evaporation of water ;

  问题2,印刷字体模糊

  Problem 2: the printing font is fuzzy

  一般印刷字体模糊,多由于油墨过于稠密,黏度太高造成甩墨不均匀而形成连墨效果,也有可能是油墨太厚,没有干燥的情况下,纸张叠加造成油墨连墨

  Generally, the printing font is fuzzy, and the ink even effect is formed due to the uneven ink rejection caused by too dense ink and too high viscosity。 It may also be that the ink is too thick and does not dry when the paper overlaps

  解决方法:调墨时注意油墨的粘稠度,当然也需要注意印刷缸与压力辘之间的压力关系,总之注意一些细节调试;

  Solution: pay attention to the viscosity of the ink, of course, also need to pay attention to the pressure relationship between the printing cylinder and the pressure roller, in a word, pay attention to some details of debugging;

  问题3,纸张压线爆裂;

  Problem 3, paper cord burst;

  一些纸张受力不均或者压力超过极限都会出现裂开的现象;

  Some paper will crack when the force is uneven or the pressure exceeds the limit;

  解决方法:注意保证纸张的湿度关系,太干燥的纸张韧性弱容易裂开,纸张的压力也不要过大,在采购纸张前注意测试纸张的抗拉力。

电竞平台  Solution: pay attention to the relationship between the humidity of the paper. If the paper is too dry, its toughness is weak and it is easy to crack. The pressure of the paper should not be too large. Before purchasing the paper, pay attention to testing the tensile strength of the paper.
