包装盒印刷中常常会出现重形，字迹模糊，字体歪曲及套印不准的现象出现，今天山东印刷包装厂家将逐个研究问题出现的原因及办法，如下：

In the printing of packaging boxes, there are often many phenomena, such as duplicate shapes, blurred handwriting, distorted fonts and inaccurate overprinting. Today, Shandong printing and packaging manufacturers will study the causes and solutions of the problems one by one, as follows:

包装盒印刷过程中如果调整不当，往往会生成印刷字体有重形出现，造成这种现象主要是设备振动过大或机速不稳所致；另外一个成因与墨辊的压力也有很大关系，这个现象我们常用方法就是在生产前把墨辊压力调好的状态，开机生产进行中匀速开机，且设备应无“带病”开机，对于字体歪曲套印不准则完全取决于操作人员对设备的调整是否完全达到好的状态，且与操作人员的熟练程度有关；

If the packaging box is improperly adjusted in the printing process, it will often produce the printing font with double shape, which is mainly caused by excessive vibration of the equipment or unstable machine speed; Another cause is also closely related to the pressure of the ink roller. Our common method to solve this problem is to adjust the pressure of the ink roller to a good state before production, start the machine at a constant speed during production, and the machine should be started without "defects". The inaccurate overprinting of font distortion depends entirely on whether the operator adjusts the machine to a good state, and is related to the proficiency of the operator;

现今由于产品包装各包装印刷厂都有严格的要求，像包装盒类对于盒子承压都有很高要求，这就要求印刷生产过程中会严格控制送纸辊的间隙压力，避免压力过大导致纸板厚度受损，瓦楞也会因受压造成愣形受损，这样就会直接导致成型后的纸箱承压降低；另一个原因影响纸板厚度成因与版面所用的材版也有很大关系。

Nowadays, due to the strict requirements of all packaging and printing plants for product packaging, such as packaging boxes, there are high requirements for box pressure, which requires that the gap pressure of the paper feeding roller should be strictly controlled during the printing production process to avoid the damage of cardboard thickness caused by excessive pressure, and the corrugation will also be damaged due to pressure, which will directly lead to the reduction of the pressure of the formed carton; Another reason that affects the thickness of paperboard has a lot to do with the plate used in the layout.

本来纸板厚度瓦楞成型能达到7.0mm~7.5mm，但经过印刷这个工序后只有7mm，有时甚达不到7mm，这是因为如果版面采用橡胶版且版面如果设计图案文字过大，在生产中为了保证印刷版面效果，就会顾及不到纸板厚度，甚压力过大会直接导致瓦楞压溃破损。据此，建议在大面积要求高的产品，尽可能采用柔性版印刷，减少因版面压力造成的纸板不合格现象；

Originally, the thickness of the corrugated board can reach 7.0mm~7.5mm, but after the printing process, it is only 7mm, sometimes even less than 7mm. This is because if the rubber plate is used for the layout and the design of the layout is too large, in order to ensure the effect of the printing layout in production, the thickness of the board will not be taken into account, and even the pressure will directly lead to the collapse of the corrugated board. Therefore, it is suggested that flexographic printing should be used as much as possible for products with high requirements in large areas to reduce the unqualified phenomenon of paperboard caused by the pressure of the layout;

很多时候碰到印迹模糊的现象人们都会采用清洗胶版来，其实，这样做都忽略了压力的问题以及重复调试版面而造成版面积墨的问题，对此建议生产前，调试完毕后再清洗胶版，且根据胶版的质量将压力调好的状态，像印迹模糊，重形现象基本可以不出现，对于透楞现象，出现这种情况不排除纸板用材问题；另一方面在于用墨的浓度以及下辊压力也有很大关系，如用墨浓度不可太稀，那样会增加版面的覆盖率，降低透楞现象发生。

In many cases, people will use cleaning the offset plate to solve the problem of blurred prints. In fact, this ignores the problem of pressure and the problem of ink area caused by repeated debugging of the plate. It is suggested that the offset plate should be cleaned before production and after debugging, and the pressure should be adjusted to a good state according to the quality of the offset plate. The phenomena such as blurred prints and reshaping can basically be avoided. For the phenomenon of corrugation, This situation does not rule out the problem of cardboard materials; On the other hand, the concentration of the ink and the pressure of the lower roller also have a great relationship. If the concentration of the ink is not too thin, it will increase the coverage of the page and reduce the occurrence of the corrugation phenomenon.

在包装盒印刷中有一个不可忽视的问题，那就是开槽带挂，切角不干净的现象，还有就是把手有裂开现象的发生，像我们常见的开槽不干净，有挂边是纸箱印刷中经常出现的现象，这与纸板材质有关；另一方面与设备的磨损也有关，像这个问题可采用提高切槽深度，减少上刀与下刀的间隙，切不可能盲目换刀，再一个对于把手有裂开，一般内切式不会出现面纸裂开，但对于外切把手，因面纸直接受力，所以我们在印刷中一定做到预压，缓冲一下，面纸直接受力（在不影响质量和强度的情况下）。有问题随时来我们网站http://www.xinfengyinshua.cn咨询！

There is a problem that cannot be ignored in the printing of packaging boxes, that is, the phenomenon of grooving and hanging, and the uncleanness of cutting corners, as well as the occurrence of cracking of the handle, such as our common phenomenon of uncleanness of grooving and hanging edges, which is a common phenomenon in carton printing, which is related to the material of cardboard; On the other hand, it is also related to the wear of the equipment. For example, to solve this problem, we can improve the cutting depth, reduce the gap between the upper knife and the lower knife. It is impossible to change the knife blindly. On the other hand, the handle is cracked. Generally, the face paper will not crack in the internal cutting type, but for the external cutting handle, because the face paper is directly stressed, we must pre-press and buffer it in printing, The face paper is directly stressed (without affecting the quality and strength).
