Tips for bronzing


1. hot stamping
      The bronzing is the use of a certain pressure and temperature, using the stencil installed on the stamping machine, so that the printed matter and the hot stamping press can be pressed together in a short time, and the metal foil or the color pigment foil can be transferred to the quilt according to the graphic requirements of the hot stamping stencil. Hot material surface processing technology. Since hot stamping is based on gold and silver, it is often called bronzing. This technology is an important process for increasing the visual effects and grades of labels, trademarks, cigarette packets, wine bags and various high-end packaging boxes. From the process can be divided into the first hot after printing and printing after the first hot. The first hot stamping is to print the foil on the blank substrate first, and then print the graphic on the surface of the aluminum foil layer, which is mostly used for packaging printing that requires large area hot stamping. The first printing and then the hot is printed on the printed matter, in the hot stamping part of the hot stamp on the desired pattern, this is a widely used technology. From the hot stamping method, it can be divided into hot stamping technology and cold stamping technology. Hot stamping technology is the hot stamping process mentioned above that requires a certain temperature and pressure to complete the transfer of galvanized aluminum foil. The cold stamping technology is a process of transferring an electro-aluminum foil to a surface of a packaged printed matter by applying a UV adhesive on a part where the printed matter needs to be stamped. These two methods have their own characteristics to meet the requirements of different products.
     2. Three-dimensional hot stamping
     The three-dimensional bronzing technology is a composite technology combining bronzing technology and embossing and embossing technology. It is the use of corrosion or engraving technology to make the bronzing and embossing graphics into a concave and a convex mold with a positive and a negative mold. Embossing technology once completed the process. This process also completes bronzing and embossing at the same time, which reduces the number of waste products that are not allowed to be processed and overprinted, and increases productivity and product quality.
     Since the three-dimensional hot stamping is a combination of hot stamping and embossing and embossing technology, the resulting product is a three-dimensional pattern in an embossed shape and cannot be printed on it. Therefore, it is necessary to adopt the process of printing first and then hot, and at the same time, due to its high precision. And high quality requirements, not suitable for cold stamping technology, but more suitable for hot stamping technology.
