正確選擇和控制油墨的印刷適性，對提高包裝印刷產(chǎn)品的質(zhì)量，追求包裝印刷品意義重大。濟(jì)南印刷廠家認(rèn)為，您應(yīng)注意選擇和調(diào)整油墨的印刷適性，使之適合于印刷工藝及承印材料的要求，從而提高產(chǎn)品的印刷質(zhì)量，降低生產(chǎn)成本，提高經(jīng)濟(jì)效益。

Correct selection and control of the printability of printing ink is of great significance to improve the quality of packaging and printing products and to pursue packaging and printing products. Jinan printing factory believes that you should pay attention to selecting and adjusting the printing suitability of the ink to meet the requirements of the printing process and printing materials, so as to improve the printing quality of the product, reduce production costs and improve economic benefits.

油墨的印刷適性主要包括油墨的流變性、觸變性、粘度、流動(dòng)度、滲透性、轉(zhuǎn)移性、顏色等。油墨具有良好的觸變性時(shí)，施印過程中有利于油墨順利、均勻地轉(zhuǎn)移，同時(shí)一旦印在紙張上后，油墨由稀變稠，保證印跡的清晰度，特別是針對網(wǎng)點(diǎn)、文字、線條版印刷，可避免油墨在紙張上浸潤、鋪展；油墨的粘度過大時(shí)。拉絲性強(qiáng)。

The printability of ink mainly includes rheology, thixotropy, viscosity, fluidity, permeability, transferability, color, etc. When the ink has good thixotropy, it is conducive to the smooth and uniform transfer of the ink during the printing process. At the same time, once printed on the paper, the ink will change from thin to thick to ensure the clarity of the print. Especially for dot, text and line printing, it can avoid the ink from wetting and spreading on the paper; When the viscosity of the ink is too high. Strong drawability.

易形成印刷中的層現(xiàn)象，在高速印刷表現(xiàn)更為明顯，很容易引起紙張的脫粉、拉毛或分離現(xiàn)象，會(huì)使油墨轉(zhuǎn)移發(fā)生困難。油墨粘度過小，流動(dòng)度增大，也會(huì)造成印刷品上臟，印跡面積擴(kuò)大、清晰度下降；印刷品色相的準(zhǔn)確程度和鮮艷程度是由油墨顏色所決定的，在彩色印刷中，油墨的顏色關(guān)系到印刷復(fù)制品的色相和色調(diào)層次是否符合原稿的要求，印刷品顏色不準(zhǔn)確，將影響產(chǎn)品質(zhì)量。

It is easy to form the layer phenomenon in printing, which is more obvious in high-speed printing. It is easy to cause the phenomenon of peeling, fuzzing or separation of paper, which will make it difficult to transfer ink. If the viscosity of the ink is too small and the fluidity is increased, the printed matter will be dirty, the printing area will be enlarged and the definition will be reduced; The accuracy and brightness of the color of the printed matter are determined by the color of the ink. In color printing, the color of the ink is related to whether the color and hue level of the printed copy meet the requirements of the original. The inaccurate color of the printed matter will affect the product quality.

另外，除選擇和控制油墨的印刷活性，油墨的耐光、耐熱性在包裝印刷設(shè)計(jì)中也應(yīng)引起足夠重視。油墨的耐光耐熱性，是指印刷物表面的圖文墨層在光源照射下，和在一定濕度范圍內(nèi)，相對地保持不變色的性能，它是油墨固有的化學(xué)性質(zhì)。

In addition, in addition to selecting and controlling the printing activity of the ink, the light and heat resistance of the ink should also be paid enough attention in the packaging and printing design. The light and heat resistance of the ink refers to the performance that the image and text ink layer on the surface of the printed matter remains relatively unchanged under the illumination of the light source and within a certain humidity range. It is the inherent chemical property of the ink.

油墨在混合、沖淡(加黑、白墨)后耐光性大大降低，印刷后很易褪色。這也是專色印刷中許多淡底色易于褪色的原因。

The light fastness of the ink is greatly reduced after mixing and diluting (adding black and white ink), and it is easy to fade after printing. This is also the reason why many light background colors are easy to fade in spot color printing.

目前，一些包裝印刷產(chǎn)品的淡底色存在褪色問題，大大影響了包裝印刷產(chǎn)品的使用效果。由此，合理運(yùn)用油墨的耐光性對提高包裝印刷產(chǎn)品的質(zhì)量是十分重要的。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://buiy.cn咨詢！

At present, there is a fading problem in the light background of some packaging and printing products, which greatly affects the use effect of packaging and printing products. Therefore, it is very important to use the light fastness of ink reasonably to improve the quality of packaging and printing products.
