Roll-to-roll laser holographic image embossing transfer production line and production process thereof

Abstract

The invention discloses a roll-to-roll laser holographic image embossing transfer production line and production process thereof. At present, by means of production process of first printing images and texts and then manufacturing holographic images, the size of images and texts which are printed by a printing film has the problem of large deformation. The roll-to-roll laser holographic image embossing transfer production line comprises a printing film unrolling device, a printing film traction device, a printing film coating system, a printing film drying channel, a printing film rolling device, a holographic biaxially-oriented polypropylene (BOPP) film unrolling device, a holographic BOPP film traction device, a holographic BOPP film coating system, a holographic BOPP film drying channel, a holographic BOPP film rolling device, a first holographic embossing device and a second holographic embossing device, wherein the printing film unrolling device, the printing film traction device, the printing film coating system, the printing film drying channel and the printing film rolling device are located on one half side of the production line and are sequentially arranged in the printing film conveying direction; the holographic BOPP film unrolling device, the holographic BOPP film traction device, the holographic BOPP film coating system, the holographic BOPP film drying channel and the holographic BOPP film rolling device are located on the other half side of the production line and sequentially arranged in the holographic BOPP film conveying direction; and the first holographic embossing device and the second holographic embossing device are located at the middle position of the production line. The production process of the roll-to-roll laser holographic image embossing transfer production line achieves the fact that laser holographic anti-counterfeiting marks are added on the surfaces of the images printed by the printing film, and simultaneously the size of the printed images is not influenced.

Description

technical field [0001] The invention relates to the field of laser holographic image production, in particular to a roll-to-roll laser holographic image embossing transfer production line and a production process thereof. Background technique [0002] In the printing and packaging industry, the focus issues that are increasingly being paid attention to at home and abroad are: ① environmental protection, ② energy saving, ③ anti-counterfeiting, ④ high efficiency, and ⑤ aesthetics. [0003] Laser holography has been widely used as an anti-counterfeiting printing technology that is intuitive and easy for consumers to identify. Holographic anti-counterfeiting products for printing and packaging mainly include laser holographic anti-counterfeiting labels, laser holographic packaging materials and laser holographic hot stamping materials. However, although the above-mentioned technology has brought into play a unique effect in the anti-counterfeiting function, it has not surpassed...
