Background

The cold stamping technology provides a new opportunity for the majority of printing enterprises and is generally used at present. Through the cold stamping technology, printing enterprises can provide more choices for customers, and the capacity of serving the customers is improved. Effectively improving the competitive strength of enterprises and creating the potential of consumption demand for the products of customers.

The cold stamping technology is a method for transferring a hot stamping foil to a printing material by using a UV adhesive. The alumite used in the cold stamping technology is a special alumite, the back surface of the alumite is not coated with glue, a UV adhesive is directly coated on a position needing decoration during printing, the alumite is contacted with the UV adhesive during transfer, the alumite is peeled off, and the color layer is hot stamped on the surface of a printed matter. And then, glazing or coating a film on the surface of the printed matter to protect the aluminum foil patterns. The cold stamping electric aluminum mainly comprises five layers: the first layer is a base film layer, generally made of polyester film, which has a load bearing and continuous function. The second layer is a coating layer, generally made of silicone resin, and has a release effect. The third layer is an information bearing layer, and the main component of the third layer is synthetic resin. The fourth layer is an aluminum plating layer, which is plated from gaseous aluminum under vacuum conditions. The fifth layer is a back coating coated on the aluminum layer. Common cold stamping electrochemical aluminum is divided into a plate seam cold stamping film and a plate seam-free cold stamping film according to the manufacturing method.

The manufacturing principle of the cold stamping film with the plate seam is as follows: the existing plate seam mould pressing is adopted, a master plate is arranged on a mould pressing machine, and a plate seam mark is left when the plate seam is pressed on a base film due to the seam existing on the master plate joint on a plate roller. The alumite surface effect of the cold stamping film with the plate seam is uniform and consistent, but when the cold stamping film is used, the plate seam is easy to stamp hot stamping printing materials to form waste products.

In the process for producing light beam and plain surface laser products without seams, because the first unit mould pressing roller is a high-temperature roller and the second unit mould pressing roller is a cold and hot double-area roller, after the first unit mould pressing roller carries out high-temperature impression imaging, a seam area is subjected to high-temperature impression, and when the area is subjected to secondary impression of the second unit mould pressing roller, the seam is easy to blacken, the color difference of the film surface is generated, and the quality of the products is seriously influenced. Although the influence of plate gaps is avoided, color difference waste products are easily caused for products with higher color control requirements, and the difficulty of quality control is increased.

In the existing cold stamping implementation process, a roller of cold stamping equipment drives a membrane surface to move forwards. The longitudinal length of the cold stamping content is usually smaller than the circumference of a roller plate, and in order to save the use of the electrochemical aluminum, a flat cold stamping device needs to be pulled back once before the next printed material arrives after a cold stamping film moves forward for a circle along with the roller. The pull-back length may be set by a control panel.
