Although sweeping technology has obvious advantages, it is not perfect. The most important feature of gold sweeps is the formation of imitation gold effects in specific areas, but it is difficult to achieve the best metallic luster and texture in a single gold sweeping process. It is not as good as gold foiling in some respects. It is not as convenient as printing gold on a printed sheet that requires a large area of ​​imitation gold, and there is no advantage in effect. Therefore, gold sweeping is only a mid-range gold-imitation effect processing technology. It has certain limitations, which restricts its rapid development to some extent. The requirements of the sweeper on the environment are very high, the temperature should be controlled at 22~25°C, and the humidity should be controlled at 50~55%, otherwise the quality problems will easily occur.

The characteristics of sweep gold craft
Sweeping gold has unique advantages when compared with other imitation gold effect processing techniques in other fine prints. Gold printing and gilding, as a widely used process, have many advantages, but there are also some deficiencies. For example, at present, gold can be offset, gravure, flexo, and screen printing, especially offset printing and gravure printing. These two printing speeds are relatively fast. The offset ink layer is thin, and the metallic luster is not very good. The gravure ink layer is thicker and the gloss is better than that of offset printing. However, the metal texture is not strong enough during large-area printing, and the deformation is relatively serious when printing small characters and thin lines. A traditional process, the metal is also very strong, but high energy consumption, relatively low efficiency, registration is difficult, very small graphics and a large area of ​​gilding, the quality is not easy to control; matte printing although there is a good metal texture And luster, but the production efficiency is low, discarded packaging is not easy to recycle, is not conducive to environmental protection. The gold sweeping technology is simple in operation, the production speed is high (up to 7500 sheets/hour), and the cost is low. Regardless of the thickness of the text and the size of the area, good results can be obtained. Gold powder color is also varied, such as gold, silver, red gold, copper, green, graphite, tan, lemon yellow, peacock blue, etc., can be described for everything, and different granularity, can show a rich color . Currently in North America and Europe, a kind of gold powder with diamond effect has begun to be popularized. The gold powder has 4 kinds of particle diameters and 10 colors. It can make the decoration and graphics shine like light diamonds, which reflects the multicolored light. Unique effect. Due to the use of metal particles as a raw material, the gold-sweeping products are more metallic sand grains and diffuse reflection effects, which are closer to the original texture of real metal. The gold sweeping product gives a distinct three-dimensional visual sense, feels smooth to the touch, and has a unique surface finish that is different from gold and bronzing. The gold-sweeping process has unique effects on the surface of the printed matter, and it also has a certain anti-counterfeiting function because it is difficult to imitate. Based on this, the gold-sweeping process has attracted the consumers of wine, cosmetics, and pharmaceuticals.
