印刷是一個比較繁瑣的過程，包括了很多的步驟和工作，其中顏色處理問題是挺重要的一個方面，那么濟南印刷廠怎么去做好顏色處理呢？

　　Printing is a tedious process, including a lot of steps and work, among which the color treatment problem is a very important aspect, so how to do a good job in jinan printing factory color treatment?

　　在印刷過程中

　　In the printing process

　　出現假墨色的原因很多，涉及的因素很多，包括紙張性能、油墨性能、印版質量、印刷橡皮布質量、印刷壓力、印刷機性能和印刷工藝。

　　There are many reasons for false ink, involving many factors, including paper performance, ink performance, plate quality, printing blanket quality, printing pressure, printing machine performance and printing process.

　　如果紙張和油墨性能穩定，印版質量滿足印刷要求，印刷機工作性能比較穩定，仍然存在不能實現油墨彩色印刷的現象，主要原因是印刷壓力的問題。

　　If the performance of paper and ink is stable, the quality of the printing plate meets the requirements of printing, and the working performance of the printing machine is relatively stable, there is still the phenomenon of color printing ink, the main reason is the problem of printing pressure.

　　在平版膠印的過程中，經常會遇到假色印刷的現象。在印刷品上，主要表現為印刷品實心部分出現斑點或空洞，圖形或線條不完整，圖像色調水平再現性差或網點丟失。

　　In the lithography offset printing process, often encountered the phenomenon of false color printing. In printed matter, mainly for printed matter solid part of spots or empty, incomplete graphics or lines, image tone level reproducibility is poor or dot loss.

　　在膠印中

　　In the offset printing

　　濟南印刷廠認為壓力的大小直接決定了印刷過程中油墨的轉移。如果在印刷過程中出現局部壓力不均，會導致印刷油墨顏色不真實。由于橡皮布滾筒安裝在印版滾筒和壓印滾筒之間，橡皮布上的每個微小單元每轉一圈都需要與兩個滾筒接觸一次。

　　Ji 'nan printing plant that the size of the pressure directly determines the transfer of ink in the printing process. If there is local pressure imbalance in the printing process, it will lead to false printing ink color. Because the blanket drum is installed between the plate drum and the imprint drum, each tiny unit on the blanket needs to contact the two drums once every turn.

　　油墨的轉移是橡皮布受壓變形的結果。橡皮布的壓縮變形是壓力的根本保證。因此，壓力的大小和均勻性直接關系到膠印所用的橡皮布。其力周期性變化。正是由于橡皮布上受力的周期性變化，會引起橡皮布的內摩擦，從而導致橡皮布老化，影響印刷壓力的均勻性，并可能導致橡皮布報廢。

　　Ink transfer is the result of blanket compression deformation. The compression deformation of blanket is the fundamental guarantee of pressure. Therefore, the size and uniformity of pressure is directly related to the rubber sheet used by offset printing. Its forces vary periodically. It is because of the periodic change of the force on the blanket, it will cause the internal friction of the blanket, resulting in the aging of the blanket, affecting the uniformity of the printing pressure, and may lead to the scrap of the blanket.

　　橡皮布在壓緊力的作用下，有很好的將印版圖文部分的油墨轉移到承印物表面的能力，即接受和釋放油墨的能力，但橡皮布會改變墨水，傳輸的能力也會導致出現假墨色的現象。包裹在滾筒上的橡皮布受到張力和壓力。隨著軋制次數的不斷增加，橡皮布壓縮變形的應力積累會變得僵硬，失去原有的柔軟性和高彈性，甚至表面會出現光亮或龜裂的痕跡，造成局部受壓不均。

　　Blanket under the action of compression force, there is a good printing plate graphic part of the ink transfer to the substrate surface, that is, the ability to accept and release ink, but blanket will change the ink, the ability to transfer will also lead to the phenomenon of false ink. The blanket wrapped around the drum is subjected to tension and pressure. With the increasing number of rolling, the stress accumulation of blanket compression deformation will become stiff, lose the original softness and high elasticity, and even the surface will appear bright or cracking traces, resulting in uneven local compression.

　　印刷廠隨著社會的發展，發展空間在不斷的提升，當我們在印刷的時候，顏色的地位是非常高的，而工作人員需要具備顏色處理的方法，更多內容就來網站www.096685.com咨詢！
