Description

A holographic plate of sand silver snowflake without plate seam

technical field

The utility model relates to the technical field of holographic anti-counterfeiting packaging and printing, in particular to a holographic plate of sand silver snowflakes without plate seams.

Background technique

Laser holographic anti-counterfeiting is the use of laser holographic plate-making technology and molding replication technology to make graphic information into anti-counterfeiting images. At present, the plate-making technologies that can be realized include: dot matrix dynamic light, one-time special laser film, 3D optical miniature background, colorful optical random interference, etc. Laser anti-counterfeiting patterns are generally observed by the user with the naked eye, or through microscopic equipment to check the internal engraving features, so as to identify the authenticity. Since the combination of color blocks in the hologram is specially designed and coded, it is difficult to produce exactly the same holographic master even with the same equipment. Therefore, laser holographic plate making technology has been widely used in the anti-counterfeiting packaging and printing industry. The widely used application process is to combine holographic The picture is directly transferred to paper products, and has been widely used in tickets, trademarks and credit cards. The labels pressed by the same template are the same, but the template is affected by various parameters and environmental conditions during the photolithography process, and it is impossible to make two identical templates, thus playing an anti-counterfeiting function.

Most of the existing holographic templates present a predetermined shape or pattern, so the uniqueness is poor and the anti-counterfeiting effect is poor.
