書刊雜志印刷膠印的墨層比較薄，印刷金色實線和粗線時，常采用兩次連續(xù)印刷或兩步印刷工藝，以達(dá)到半濃墨層的飽和度和金屬光澤效果。銀墨的印刷適性優(yōu)于金墨，基本可以滿足一般包裝印刷只需一次印刷的要求，以很好地呈現(xiàn)銀色光澤，在書刊雜志印刷金（銀）墨時的注意事項有哪些？下面
濟(jì)南書刊雜志印刷廠家為您講解：
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)注意先選擇底漆然后打印金（銀）墨
(1) Pay attention to select primer first and then print gold (silver) ink
用膠印機(jī)印刷金墨時一般先印底色（俗稱底漆），即選擇遮蓋力強(qiáng)、顏色和金（與銀相近的油墨）油墨作為底色色，然后在底色墨層上印上金（銀）墨，既可以節(jié)省金（銀）墨，又可以提高金（銀）墨層的光澤度，強(qiáng)化金（銀）墨層銀）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（銀）墨印在基色墨上
(2) Pay attention to the printing of gold (silver) ink on the primary color ink
底色印刷質(zhì)量是決定金（銀）墨印刷質(zhì)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，干燥要適中，墨層要厚?；母稍锓椒☉?yīng)采用滲透干燥和氧化結(jié)膜干燥相結(jié)合，避免基色墨層結(jié)晶。印刷金（銀）墨時應(yīng)在底色墨層完全干透之前進(jìn)行套印，否則可能不易印刷金（銀）墨或附著牢度差，摩擦后會脫落。
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)注意油墨疊加在金（銀）墨層上
(3) Note that the ink is superimposed on the gold (silver) ink layer
除了金粉本身的金屬光澤外，重要的是表面對光線有反光作用。如果在金墨層上印刷其油墨，油墨的顏色會影響金墨層的金屬光澤效果。因此在設(shè)計印刷工藝時應(yīng)考慮到這一點，充分利用金墨的高遮蓋力和強(qiáng)遮蓋力，合理安排印刷色序，盡量將金墨安排在后一個顏色中。
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.
The precautions for printing gold (silver) ink for books, magazines and magazines have been explained from three aspects. If you have any doubts or needs about this, please come to our website http://www.aozhouhui.com Consult us and provide you with satisfactory service!
