常见的包装盒印刷失误归纳!

  针对于下面几种比较常见的包装盒印刷失误,做了一个归纳:

  In view of the following common printing errors of packaging boxes, a summary is made:

  问题1,尺寸不对,出现移位现象;

  Question 1: The size is not right and displacement occurs.

  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最后包装盒尺寸出现偏差;

  Dimension problems usually arise from the deviation of slotting knife position, or small displacement of machine in the operation process. It is also possible that irregular paper and bending phenomena result in the deviation of 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: Can adjust the position of slotting knife proofing debugging, if it is caused by paper bending, paper can be leveled, general paper warehouse need to ensure a certain humidity, so more conducive to paper storage, paper in a humid environment, the part that contacts the air will absorb water while the part that does not contact the air will cause paper bending because of moisture evaporation. ;

  问题2,印刷字体模糊

  Question 2: Blurred typeface

  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 blurred, mostly because the ink is too dense and the viscosity is too high, which results in the uneven ink rejection and the formation of ink linking effect. It may also be that the ink is too thick, without drying, the paper overlap causes ink linking.

  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: When adjusting ink, pay attention to the consistency of ink, of course, also need to pay attention to the pressure relationship between printing cylinder and pressure roller, in short, pay attention to some details of debugging;

  问题3,纸张压线爆裂;

  Question 3: Line-pressing burst of paper;

  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 papers 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。

  Solution: Pay attention to the humidity relationship of paper, too dry paper is weak and easy to crack, paper pressure should not be too large, pay attention to test the tensile strength of paper before purchasing paper.
