Cold Stamping Technology Features and Requirements

Cold Stamping Technology Features and Requirements

Cold stamping technology has provided new opportunities for printing companies. Its greatest advantage is less investment, or even no investment at all. Another outstanding advantage is the high cost performance, which is also the biggest selling point of cold stamping technology. As some industry insiders said: 'For customers, cold stamping technology has a higher cost performance, can help customers increase the added value of the product, and very cost-effective' In addition, since the cold stamping technology does not require the production of expensive hot stamping version, so It is very suitable for short-lived, low-quality labeling and proofing production. However, compared with the hot stamping technology, the cold stamping technology still has certain defects in quality and needs to be further improved. Therefore, the cold stamping technology is not suitable for the processing of high quality packaging and label products. Although gold and silver ink printing can also achieve metallic gloss decorative effects similar to those of hot stamping, and gold and silver ink printing technologies have made great progress in recent years, they still cannot achieve hot stamping or cold stamping technology. The kind of intense visual impact it brings.

In general, cold stamping can usually be applied to a job printed on a UV flexographic printing press. The cold stamping process requires the following equipment and materials:

1. Standard flexographic printing or embossing unit.

2, photosensitive resin plate and anilox roller, and must have enough spare anilox roller to choose from.

3. The embossing roller with a hardness of HS90 must be able to be easily installed in the printing unit, and it must be ensured that sufficient pressure is provided to ensure that the hot stamping is carried out.

4, hot stamping foil unwinding device and winding device. Care should be taken to adjust the winding tension when cleaning waste to avoid wrinkling or delamination of the stamping material.

5, hot stamping foil.

6, UV adhesives.

7, UV curing system. The UV curing system must be as close as possible to the imprinting device in order to cure the UV adhesive in time after printing and stamping. It is required that the power of the UV curing system should be at least 300 W. The UV lamp and the reflector must be kept clean and free of UV varnish and dust impurities so as not to affect the curing effect of the UV adhesive.

8, stripping device. The peeling device is installed at the back end of the UV curing system. In addition to peeling the waste foil, the device can also prevent the delamination phenomenon of the hot stamping foil before the UV curing, and can also reduce the wrinkle, skew and other defects of the printing material.

In addition, in order to obtain high-quality hot stamping products and high profit margins, skilled operators are also required to be able to handle and solve various problems in the production process, especially those related to UV systems. .

In the actual production, the use of hot stamping technology can achieve the best hot stamping quality and hot stamping effect, but the cost is higher. Although the quality of cold stamping is not bad, it is inferior to hot stamping, but at a lower cost. No matter which kind of hot stamping technology you use, you should pay attention to these two types of hot stamping technology, because the price of hot stamping is constantly lowered, and the quality of cold stamping is also increasing, both stamping technologies are constantly in Progress and development.
