实际上所有的机械印刷方法都是由这四类印刷方法演变而来的，因此，人们把使用有形图像载体（印版）的印刷方法统称为传统印刷。传统印刷的油墨从印版到承印物转移是以润湿原理为基础的。下面济南印刷厂家就来为您讲讲印刷过程中润湿基本原理。

In fact, all mechanical printing methods are evolved from these four types of printing methods. Therefore, printing methods using tangible image carriers (printing plates) are collectively referred to as traditional printing. The transfer of traditional printing ink from printing plate to substrate is based on the wetting principle. Now Jinan Printing Factory will tell you the basic principle of wetting in the printing process.

自然界中的物体表面上的一种流体被另一种流体取代的过程称为润湿。因此，润湿必须涉及三相，即气相、液相和固相，其中少有两相为流体。在一般的生产实践中，润湿是指固体表面上的气体被液体取代的过程。固体的表面被液体润湿后，便形成了“气——液”“气——固”、“液—固”三个界面，通常把由气相组成的界面叫做表面，即把“气——液”界面叫做液体表面，“气一固”界面叫做固体表面。

The process in which one fluid on the surface of an object in nature is replaced by another is called wetting. Therefore, wetting must involve three phases, namely gas phase, liquid phase and solid phase, at least two of which are fluids. In general production practice, wetting refers to the process in which the gas on the solid surface is replaced by the liquid. After the surface of a solid is wetted by a liquid, three interfaces, namely "gas liquid", "gas solid" and "liquid solid", are formed. Generally, the interface composed of the gas phase is called the surface, that is, the "gas liquid" interface is called the liquid surface, and the "gas solid" interface is called the solid surface.

平版胶印印刷中的润湿问题较多且复杂，例如，油墨从印刷机的墨斗传出，经过墨辊、印版、橡皮布，印刷图文部分的油墨被转移到承印物表面，具备什么样的条件。

There are many and complex wetting problems in offset printing. For example, what conditions do you have when the ink flows from the ink bucket of the printing machine, passes through the ink roller, printing plate, and blanket, and the ink in the printed image and text part is transferred to the surface of the substrate.

油墨可以取代各个印刷表面上的气体（空气），将固体表面转变为稳定的液——固界面，使油墨传递均匀怎样改变油墨和印刷面的润湿性能，提高油墨传输、转移效率如何增强润湿液对平版空白部分的润湿性，防止版面起脏等问题都和润湿有关，可以说润湿是物质微观特性的宏观表现。

The ink can replace the gas (air) on each printing surface, transform the solid surface into a stable liquid-solid interface, make the ink transfer uniform. How to change the wettability of the ink and the printing surface, improve the ink transmission and transfer efficiency, how to enhance the wettability of the wetting solution to the blank part of the lithography, and how to prevent the page from getting dirty are all related to wettability. It can be said that wettability is the macroscopic expression of the microscopic characteristics of substances.

研究探讨印刷过程中的润湿问题，可为提高材料的印刷适性以及进行印刷新材料、新工艺的研究，提供必要的理论依据。

The study of the wetting problem in the printing process can provide the necessary theoretical basis for improving the printability of materials and researching new printing materials and processes.
