At present, cold stamping has become an important surface decoration method in the processing of self-adhesive labels, which can achieve exquisite metal stamping effects and greatly enhance the shelf attractiveness of products. It can be said that the application of cold stamping on self-adhesive labels Let people’s lives become colorful.
On the whole, cold hot stamping solves the problem of poor adaptability of traditional hot stamping, difficult process control, single expression of patterns and text (especially solving the problem of hot stamping of mesh images and thin lines), and production A series of constraints brought about by cycle factors can also easily complete the connection operation, allowing label printing companies to achieve “one-stop” printing and processing of self-adhesive labels. Self-adhesive label cold stamping also has the following advantages.
1. Flexible and diverse forms
Cold hot stamping is a label finishing process that uses pre-printed UV adhesive and hot stamping foil cold press peeling technology, which can be achieved by traditional printing such as flexographic, embossed, and offset printing. Therefore, the expressive power of cold-stamping patterns can get a great breakthrough, and it can realize hot-stamping on the spot, lines and high precision mesh. Hot stamping on the surface of the printed pattern or printing ink on the surface of the stamped pattern can have a unique effect of see-through or cover, showing a bright metallic texture.
2, cost saving, less pollution
Compared with hot stamping, cold stamping only requires the cooperation of the printing unit and the laminating unit, and does not require special stamping equipment and molds. This not only helps label printing companies reduce the investment in hot stamping equipment, and does not need to make hot stamping plates, but can use traditional printing plates, which eliminates the chemical corrosion process of making metal plates. The plate making speed is fast and the cycle is short. It also reduces the environmental impact. The pollution, the termination of resources.
3. It is more suitable for the surface of film adhesive materials
At present, a considerable part of daily chemical labels, especially high-end daily chemical labels, have adopted film adhesive materials. Cold hot stamping does not require high temperature and strong pressure. The transfer drying temperature is generally 40～50℃, which is more conducive to hot stamping on the surface of the film adhesive material.
4. Fast printing speed
The fastest speed of cold stamping can reach 60-100 meters/minute. For label printing companies, this means an increase in production capacity, which is more conducive to reducing costs.
