书刊杂志印刷胶印的墨层比较薄,印刷金色实线和粗线时,常采用两次连续印刷或两步印刷工艺,以达到半浓墨层的饱和度和金属光泽效果。银墨的印刷适性优于金墨,基本可以满足一般包装印刷只需一次印刷的要求,以很好地呈现银色光泽,在书刊杂志印刷金(银)墨时的注意事项有哪些?下面
济南书刊杂志印刷厂家为您讲解:
The ink layer for offset printing of books, periodicals and magazines is relatively thin. When printing gold solid line and thick line, two continuous printing or two-step printing processes are often used to achieve the saturation of semi-thick ink layer and metallic luster effect. The printability of silver ink is better than that of gold ink, which can basically meet the requirement that only one printing is required for general packaging printing, so as to well present the silver luster. What are the precautions when printing gold (silver) ink in books and magazines? Next, Jinan book and magazine printing factory will explain to you:
(1)注意先选择底漆然后打印金(银)墨
(1) Pay attention to select primer first and then print gold (silver) ink
用胶印机印刷金墨时一般先印底色(俗称底漆),即选择遮盖力强、颜色和金(与银相近的油墨)油墨作为底色色,然后在底色墨层上印上金(银)墨,既可以节省金(银)墨,又可以提高金(银)墨层的光泽度,强化金(银)墨层银)油墨印刷效果。
When printing gold ink with an offset press, the background color (commonly known as the primer) is generally printed first, that is, the ink with strong covering power, color and gold (ink similar to silver) is selected as the background color, and then the gold (silver) ink is printed on the background color ink layer, which can not only save the gold (silver) ink, but also improve the gloss of the gold (silver) ink layer, and strengthen the printing effect of the gold (silver) ink layer silver) ink.
(2)注意金(银)墨印在基色墨上
(2) Pay attention to the printing of gold (silver) ink on the primary color ink
底色印刷质量是决定金(银)墨印刷质量的重要因素,因此印刷底色墨的版面要平整,底墨的粘度要高,干燥要适中,墨层要厚。基色墨的干燥方法应采用渗透干燥和氧化结膜干燥相结合,避免基色墨层结晶。印刷金(银)墨时应在底色墨层完全干透之前进行套印,否则可能不易印刷金(银)墨或附着牢度差,摩擦后会脱落。
The printing quality of the background color is an important factor that determines the printing quality of gold (silver) ink. Therefore, the layout of the printing background color ink should be flat, the viscosity of the background ink should be high, the drying should be moderate, and the ink layer should be thick. The drying method of the primary ink should be the combination of penetration drying and oxidation film drying to avoid the crystallization of the primary ink layer. When printing gold (silver) ink, it should be overprinted before the background ink layer is completely dry, otherwise it may not be easy to print gold (silver) ink or the adhesion fastness is poor, and it will fall off after rubbing.
(3)注意油墨叠加在金(银)墨层上
(3) Note that the ink is superimposed on the gold (silver) ink layer
除了金粉本身的金属光泽外,重要的是表面对光线有反光作用。如果在金墨层上印刷其油墨,油墨的颜色会影响金墨层的金属光泽效果。因此在设计印刷工艺时应考虑到这一点,充分利用金墨的高遮盖力和强遮盖力,合理安排印刷色序,尽量将金墨安排在后一个颜色中。
In addition to the metallic luster of the gold powder itself, it is important that the surface reflects light. If the ink is printed on the gold ink layer, the color of the ink will affect the metallic luster effect of the gold ink layer. Therefore, when designing the printing process, we should take this into account, make full use of the high and strong hiding power of gold ink, reasonably arrange the printing color sequence, and try to arrange the gold ink in the next color.
