Cover technology usually includes UV, drumming, frosting, bronzing, grinding and cutting.
UV is to make the part of UV bright, and it is slightly convex to the touch, but the convex is not visible. UV is mainly to increase the brightness of the product and protect the surface of the product. Its hardness is high, corrosion resistance is resistant to friction, and scratches are not easy to appear. Some laminated products are now replaced with UV, which can meet environmental protection requirements, but UV products are not easy to bond, and some can only It is solved by local UV or sanding.
Hot stamping is also called “hot stamping”. It is to heat the metal printing plate, apply foil, and imprint golden characters or patterns on the printed matter. With the rapid development of hot stamping foil and packaging industry, the application of anodized aluminum hot stamping has become more and more extensive. Hot stamping can make the pattern clear and beautiful, the color is bright and eye-catching, wear-resistant and weather-resistant. The most typical hot stamping is the gold lettering on the hard cover of the hardcover children’s book. It can be hot in a variety of colors, such as Korean popular novels often hot in blue, gold and blue. There is also laser gold, which has a laser refraction effect.
Frosted printing is to print a layer of transparent UV frosted ink on the substrate with mirror gloss, which is cured by UV to form a rough surface like ground glass, and screen printing is often used. Because the pattern obtained by this kind of printing is very similar to the effect of metal corrosion and has a special roughness, it is also called imitation metal etching printing.
Drumming refers to the use of a die-cutting machine to make the convex/concave effect, so that the characters (or patterns) are raised.
Grinding is like carving or paper-cutting, making shapes on paper.
There is also colorful UV, which is similar to the effect of colorful powder on New Year cards.
