在画册印刷中，由于各种原因导致印刷过程中出现掉版现象，导致这种问题出现的原因有很多，今天，就给大家具体介绍一下济南画册印刷掉版的原因。

In the printing process of picture albums, there are many reasons for the phenomenon of plate loss due to various reasons. Today, I will give you a specific introduction to the reasons for plate loss in Jinan picture album printing.

1、版面水分大小控制不当。

1. Improper control of moisture content in the layout.

如果版面水分过大，就是使版面及墨辊带有一层较厚的水膜，进而影响油墨的正常均匀转移和涂布，这样就容易引起掉版现象，而且版面水分过大还会使印刷墨色偏淡，对此如果盲目采取增加输墨量来提高墨色浓度的话，则会因水大墨大造成乳化过度，而且如果版面水分偏小，则无法与油墨抗衡，使版面油墨层铺展，也会引起糊版现象。

If the moisture content of the layout is too high, it means that the layout and ink rollers have a thick layer of water film, which affects the normal and uniform transfer and coating of ink. This can easily cause plate loss, and excessive moisture content of the layout can also make the printing ink color lighter. If blindly increasing the ink output to increase the ink concentration, it will cause excessive emulsification due to high water content and ink, and if the moisture content of the layout is too small, it will not be able to compete with the ink, Spreading the ink layer on the layout can also cause a paste phenomenon.

2、润版液酸碱度太强。

2. The acidity and alkalinity of the fountain solution are too strong.

如果润版液酸性太强的话就会腐蚀画册印刷砂目，破坏印版的亲水层，容易使印刷图文在压印刷过程中被磨掉，因此，润版液的PH值在5左右刚刚好。

If the acidity of the fountain solution is too strong, it will corrode the sand mesh of the album printing, damage the hydrophilic layer of the printing plate, and easily cause the printed images and texts to be worn off during the pressure printing process. Therefore, the pH value of the fountain solution is just around 5.

2、油墨粘度过大。

2. Ink viscosity is too high.

胶印过程中如果油墨的粘度过大，除了使油墨转印出现困难以外，还会破坏墨层中间断裂的条件，使版面剩余的墨层不足，其结果就会使印版图文部分裸露磨损，造成掉版。

If the viscosity of the ink is too high during the offset printing process, in addition to making it difficult to transfer the ink, it can also damage the condition of the middle fracture of the ink layer, resulting in insufficient remaining ink layer on the printing plate. As a result, the exposed and worn parts of the printing plate, causing plate loss.

4、着墨辊老化。

4. Aging of the inking roller.

着墨辊老化后，亲水性能就会增强，而亲油墨的性能就会减弱，导致传递油墨的性能差，在机械滚压的过程中，形成“水包油”类型的油墨乳化，之后导致印版油腻和武汉画册印刷图文部分掉版。

After the aging of the inking roller, the hydrophilicity will be enhanced, while the hydrophilicity of the ink will be weakened, resulting in poor ink transfer performance. During the mechanical rolling process, an "oil in water" type of ink emulsification is formed, which later leads to greasy printing plates and partial printing of images and texts in Wuhan picture albums.

5、设备老化。

5. Equipment aging.

当设备使用老化时，一些关键部件润滑不良造成磨损、松动，如滚筒轴头、轴瓦、齿轮部件、偏心套等。那么，滚筒在合压过程中，便容易产生微量的颤动或滑动现象，从而加剧对印版版面摩擦磨损，致使印迹转移过程中挤压变形间接引起掉版、糊版的现象的产生。

When the equipment is aging, poor lubrication of some key components can cause wear and looseness, such as drum shaft heads, bearing shells, gear components, eccentric sleeves, etc. So, during the pressing process, the drum is prone to slight shaking or sliding, which exacerbates the friction and wear of the printing plate and plate, leading to the indirect occurrence of plate loss and paste caused by the compression deformation during the transfer of the imprint.

另外，橡皮布不平整也会导致画册印刷出现掉版的现象。当橡皮布的衬垫不平或包勒不紧出现虚松情况时，其表面产生隆起现象，压印时产生不正常的摩擦而破坏印版膜层，从而引起掉版、糊版现象的产生。更多相关内容了解就来咨询我们http://www.xinfengyinshua.cn吧！

In addition, the unevenness of the rubber blanket can also lead to the phenomenon of plate loss in the printing of the album. When the cushion of the rubber blanket is uneven or the wrapping is not tight, there is a phenomenon of virtual looseness on its surface, which causes abnormal friction during embossing and damages the printing plate film layer, resulting in plate loss and pasting.
