With the variety of printed products, more and more people have put forward higher requirements and expectations for printing quality. For the improvement of printing quality, gold and silver cardboard is the most direct and effective choice; however, when using gold and silver cardboard for printing, there are still many precautions; the details are as follows:
　　 First, the design notes of gold and silver cardboard.
　　 The surface of the gold and silver cardboard has high brightness and strong reflectivity. Therefore, according to the characteristics of the material, when designing the layout, attention should be paid to highlight the metallic luster of the gold and silver cardboard and laser paper that cannot be displayed by the spectral color. Appropriately reveal the metallic hue of the surface to express the artistic beauty of the package.
　　 Because the brightness of the surface of the gold and silver cardboard is high, the micro-overprinting is not easy to be observed by the naked eye, so it should be avoided to carry out fine overprinting of the multi-colored layouts. For the layout with fine overprint on the layout, consider extending the margin of the tinted overprint to about 0.2mm to avoid significant whiteness due to overprinting errors.
　　 When planning gold and silver cardboard with a combination of field, line, text and image, avoid using too fine blackface and fine Yinxian to avoid the simple rendering of the paste and affect the print quality of the product. Text, lines, borders, and logos should best be overprinted on the background and planned to be dark to make them stand out.
　　 Second, the printing notes of gold and silver cardboard.
　　 The gold and silver card is different from the normal paper for the design manuscript. If the whole manuscript is printed on the gold and silver card, the effect will not come out; the request for color should be at least 50%. The role that comes out is ambition. If there is a local area to stay white, then in the planning draft, you must make a spot color version in the white direction.
　　 Gold and silver card is a kind of special paper, which is a layer of gold and silver foil in the base of single copper or gray paper. This material does not easily absorb ink when printed. Therefore, in printing, a quick-drying ink is used for printing. Generally, the ink is not printed; the printer must have an air-drying system.
　　 Because the gold and silver card is a kind of resurrection material. It is very easy to drag and drop during production printing. Therefore, the loss paper required for the gold and silver card is also particularly large. And you must be too deserted, if it is not deserted, then you can sell this batch of goods to the waste paper recycling station. It takes up to two days after printing to dry the ink.
　　 Third, gold and silver cardboard printing ink selection.
　　 In general, when printing on gold and silver cardboard, a special printing ink is used; this ink has the following characteristics:
　　 1. It solves the problems of deinking, slow drying and unstable drying which are easy to occur when printing gold and silver cardboard, aluminum foil paper, etc. without ink-absorbing substrates.
　　 2. Make the printing offsetting machine replace the UV printing gold and silver cardboard, aluminum foil and other non-absorbent substrates.
　　 3. It also effectively solves the technical problems of fast crusting and ink roller on the same type of ink machine. It also has its superiority in transfer performance, and the color brightness of printing is better than UV printing.
