實際上所有的機(jī)械印刷方法都是由這四類印刷方法演變而來的，因此，人們把使用有形圖像載體（印版）的印刷方法統(tǒng)稱為傳統(tǒng)印刷。傳統(tǒng)印刷的油墨從印版到承印物轉(zhuǎn)移是以潤濕原理為基礎(chǔ)的。下面濟(jì)南印刷廠家就來為您講講印刷過程中潤濕基本原理。

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.

自然界中的物體表面上的一種流體被另一種流體取代的過程稱為潤濕。因此，潤濕必須涉及三相，即氣相、液相和固相，其中少有兩相為流體。在一般的生產(chǎn)實踐中，潤濕是指固體表面上的氣體被液體取代的過程。固體的表面被液體潤濕后，便形成了“氣——液”“氣——固”、“液—固”三個界面，通常把由氣相組成的界面叫做表面，即把“氣——液”界面叫做液體表面，“氣一固”界面叫做固體表面。

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.

平版膠印印刷中的潤濕問題較多且復(fù)雜，例如，油墨從印刷機(jī)的墨斗傳出，經(jīng)過墨輥、印版、橡皮布，印刷圖文部分的油墨被轉(zhuǎn)移到承印物表面，具備什么樣的條件。

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.

油墨可以取代各個印刷表面上的氣體（空氣），將固體表面轉(zhuǎn)變?yōu)榉€(wěn)定的液——固界面，使油墨傳遞均勻怎樣改變油墨和印刷面的潤濕性能，提高油墨傳輸、轉(zhuǎn)移效率如何增強潤濕液對平版空白部分的潤濕性，防止版面起臟等問題都和潤濕有關(guān)，可以說潤濕是物質(zhì)微觀特性的宏觀表現(xiàn)。

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.

研究探討印刷過程中的潤濕問題，可為提高材料的印刷適性以及進(jìn)行印刷新材料、新工藝的研究，提供必要的理論依據(jù)。

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.
