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.

油墨層厚度與紙張印刷適應性的關系處理

Relationship between ink layer thickness and paper printability

如果處理對油墨吸收快、吸墨量大、平滑度差的紙張，如果不給足夠的壓力或者不均勻的壓力，容易在印后露底并且發花。而一旦一味加大油墨量，墨層又會偏厚，就會出現粘臟的。小編告訴你這是產生粘臟的一個非常重要的原因。

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.

所以解決的時候就要從防粘臟的角度考慮，印刷大面積的圖版應采用“深墨薄印”，即把油墨的色相調得深一點，墨層相應薄一點。這樣一舉雙得，既不會影響色相，也不會粘臟。

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.

正確認識印刷壓力與墨層厚度的關系

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

適當的印刷壓力是實現版面油墨層均勻轉移的重要條件，版面壓力不足或不均勻都會影響墨層的均勻轉移。印刷中當版面壓力不足或不均勻時，印品墨色會發花，整個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，的確可以彌補因印刷壓力不足所造成的版面墨層與承印物間接觸不良而產生的缺陷，但也容易引起印品粘臟。故應先調節好印刷壓力，再調整版面輸墨量，這樣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.

避免因印刷墨層厚度不當引起的背面粘臟

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

準確無誤的去判斷墨層的厚度是否適中，以及受壓是否均勻，版面受墨均勻達到不露底、不虛印，印品色相與樣稿相符等為主要依據。

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.

若印刷壓力不均勻或不足，印刷紙張光澤度差，印品原稿色相深，油墨色相調得偏淡，都容易導致對印刷墨層厚度的判定失準。此時若盲目加大墨量，就會因墨層過厚而導致印品背面粘臟。

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.

版材質量、印刷墨層厚度和印刷壓力有一定的關系。版面光滑度差，其印刷所需的墨層和壓力就大；反之則小。這一方面也要多加了解，詳細內容就來我們網站https://www.fumeijia.net咨詢吧！

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.
