随着现在人们对纸张使用的重视，印刷纸本成为流行趋势，选择一家印刷公司是很重要的，今天我们来了解下在印刷纸本的过程中出现黑点的原因。

With people's attention to the use of paper, printing paper has become a popular trend. It is very important to choose a printing company. Today, let's understand the reasons for black spots in the process of printing paper.

印刷压力的影响

Influence of printing pressure

1、印刷压力：主要是油墨跟印刷纸张之间的磨合过程。

1. Printing pressure: mainly the running in process between ink and printing paper.

2、印刷压力的控制并非易事：印刷压力想要控制需要技术，想要做好需要从各个方面去入手。

2. It is not easy to control the printing pressure: it requires technology to control the printing pressure, and it needs to start from all aspects to do a good job.

油墨黏度对印刷的影响

Influence of ink viscosity on Printing

油墨是导致印刷纸本表面带有黑点的主要原因

Ink is the main cause of black spots on the surface of printing paper

1、油墨黏度对印刷纸本的影响实验。

1. Experiment on the influence of ink viscosity on printing paper.

2、油墨的黏度合适是很关键的一个点。

2. The proper viscosity of ink is a key point.

对湿式叠印效果有很大影响，油墨的黏度大墨层表现出较大的内聚力。

It has a great influence on the wet overprint effect. The viscosity of the ink is large, and the ink layer shows great cohesion.

①如果先印油墨黏度比后印油墨的黏度低后印油墨会依赖自身的内聚力。

① If the viscosity of the first printing ink is lower than that of the second printing ink, the latter printing ink will rely on its own cohesion.

②先印的油墨粘走，产生“逆叠印”造成混色控制好黏度是比较重要的。

② The first printing ink sticks away, resulting in "reverse overprint" and color mixing. It is more important to control the viscosity well.

如果大家在印刷纸本之后发现上面有黑点的话，需要及时的跟济南印刷厂家联系作出修改，不然可能会影响纸本的正常使用。此外原纸表面出现斑点，一般都是由于原纸的问题，因为原纸在生产过程中，里面残渣了熟料成分的物质，通过面纸加热过程起到化学作业，细小的塑料颗粒融化后产生大小不一的黑色斑点，这种情况出现较多的是以再生纸为纸基的挂面纸。

If you find black spots on the paper after printing, you need to contact the Jinan printing factory in time to make modifications, otherwise it may affect the normal use of the paper. In addition, the appearance of spots on the surface of the base paper is generally due to the problem of the base paper, because in the production process of the base paper, there is a residue of clinker ingredients, which plays a chemical operation through the heating process of the surface paper. After the melting of fine plastic particles, black spots of different sizes are produced. This kind of situation occurs more often in the surface paper based on recycled paper.
