Seamless laser hot stamping foil

In 2006, Kurtz will develop a new hot stamping foil program, according to the company, it will bring a "major breakthrough in continuous pattern holographic anti-counterfeiting foil." This solution is named seamless laser and uses a continuous stamping foil that diffracts the joints produced by the imposition in the design pattern.

Since the emergence of a continuous pattern of hot stamp foils, manufacturers have found ways to eliminate these so-called imposition seams. Utilizes ultra-fine structure to realize illusion color in holographic hot stamping foil through light refraction. A special master cylinder tool was used to mold these gratings onto the surface of the foil. It has not been possible to eliminate joints until now, and the factory has been trying hard to eliminate them or make them less noticeable, but due to the limitations of production technology, this problem still cannot be solved.

Kurz finally succeeded in developing a new production technology that can completely eliminate these seams. The company's product range includes vertical seamless stamping foils that apply a large area of ​​rainbow effect. According to Kurtz, these foils are called seamless laser foils and are very popular with customers and markets and have achieved great success. Therefore, Kurz now applies these new production methods to a variety of different laser pattern designs. They no longer have repetitive seams in the width direction. However, the vertical running direction of the foil with a repetition width of less than 620 mm is no longer present. Since April 2006, the new seamless laser hot stamping foil process has been applied to five patterns. The color is silver. It is especially suitable for use in the designated products of the paper industry. Special colors and designs are possible. produce.
