There will always be problems in the process of printing and packaging. What we need to do is to know in advance which problems should be properly prevented. Now let's talk about how to solve the sticky problem in Jinan printing and packaging.

油墨层厚度与纸张印刷适应性的关系处理

Relationship between ink layer thickness and paper printability

如果处理对油墨吸收快、吸墨量大、平滑度差的纸张，如果不给足够的压力或者不均匀的压力，容易在印后露底并且发花。而一旦一味加大油墨量，墨层又会偏厚，就会出现粘脏的。小编告诉你这是产生粘脏的一个非常重要的原因。

If the paper with fast ink absorption, large ink absorption and poor smoothness is processed, it is easy to expose the bottom and send out flowers after printing if insufficient pressure or uneven pressure is not given. Once you increase the amount of ink, the ink layer will be thicker, and it will be dirty. Xiao Bian tells you that this is a very important reason for sticky dirt.

所以的时候就要从防粘脏的角度考虑，印刷大面积的图版应采用“深墨薄印”，即把油墨的色相调得深一点，墨层相应薄一点。这样一举双得，既不会影响色相，也不会粘脏。

Therefore, when solving the problem, we should consider from the perspective of anti sticking and dirt. The printing of large areas of plates should adopt "deep ink thin printing", that is, adjust the color hue of the ink a little deeper, and the ink layer should be correspondingly thin. In this way, you can get both at one stroke, which will neither affect the hue nor stick dirt.

正确认识印刷压力与墨层厚度的关系

Correct understanding of the relationship between printing pressure and ink layer thickness

适当的印刷压力是实现版面油墨层均匀转移的重要条件，版面压力不足或不均匀都会影响墨层的均匀转移。印刷中当版面压力不足或不均匀时，印品墨色会发花，整个版面墨色厚薄也不一致。

Proper printing pressure is an important condition to realize the uniform transfer of ink layer in the layout. Insufficient or uneven printing pressure will affect the uniform transfer of ink layer. In printing, when the layout pressure is insufficient or uneven, the ink color of the printed matter will be blurred, and the thickness of the ink color of the entire layout is also inconsistent.

加大墨量，的确可以弥补因印刷压力不足所造成的版面墨层与承印物间接触不良而产生的缺陷，但也容易引起印品粘脏。故应先调节好印刷压力，再调整版面输墨量，这样才能得到好的印刷效果。

Increasing the amount of ink can indeed make up for the defects caused by poor contact between the ink layer of the layout and the substrate due to insufficient printing pressure, but it is also easy to cause the printing to stick dirty. Therefore, the printing pressure should be adjusted first, and then the ink input of the layout should be adjusted, so as to obtain a good printing effect.

避免因印刷墨层厚度不当引起的背面粘脏

Avoid dirt on the back caused by improper printing ink layer thickness

准确无误的去判断墨层的厚度是否适中，以及受压是否均匀，版面受墨均匀达到不露底、不虚印，印品色相与样稿相符等为主要依据。

Accurately judge whether the thickness of the ink layer is appropriate, whether the pressure is even, whether the layout is evenly inked without exposing the bottom and false printing, and whether the color of the printed matter is consistent with the sample.

若印刷压力不均匀或不足，印刷纸张光泽度差，印品原稿色相深，油墨色相调得偏淡，都容易导致对印刷墨层厚度的判定失准。此时若盲目加大墨量，就会因墨层过厚而导致印品背面粘脏。

If the printing pressure is uneven or insufficient, the gloss of the printing paper is poor, the original color of the printed matter is deep, and the ink color is dim, it is easy to lead to inaccurate determination of the thickness of the printing ink layer. At this time, if you increase the amount of ink blindly, it will cause the back of the printed matter to be dirty due to the thick ink layer.

版材质量、印刷墨层厚度和印刷压力有一定的关系。版面光滑度差，其印刷所需的墨层和压力就大；反之则小。这一方面也要多加了解，详细内容就来我们网站https://www.fumeijia.net咨询吧！

Plate quality, printing ink layer thickness and printing pressure have a certain relationship. The poor smoothness of the layout results in a large ink layer and pressure required for printing; On the contrary, it is small. In this respect, we should also learn more.
