Hologram foil stamping

September 16, 2019

Hologram foil stamping : laser hologram is made by using the method of spatial frequency coding according to the principle of laser interference.Laser holograms are widely used in the field of anti-counterfeiting because of their good color, obvious level, vivid and vivid image, good optical transformation effect and high information technology content.The latest optical alterable patterning technology is clearly distinguished from the HOLOGRAM (three-dimensional HOLOGRAM) holograms that are widely used, some of which have machine recognition capabilities.The mechanism of the holographic hot stamping is on hot stamping equipment by heating the hot stamping die head to the hot melt glue line on the holographic stamping materials and separation layer heated to melt, under certain pressure, hot stamping material information layer holographic grating stripe and PET substrate separation, make information layer and steamed adhesive, aluminum foil, to achieve a perfect combination.Holographic hot stamping is mainly common hot stamping and positioning hot stamping two kinds.One special version of hologram positioning hot stamping in the past two years in the high - end cigarette package appeared frequently.It refers to the hot stamping equipment through photoelectric identification hologram security hot stamping anodized on a specific part of the hologram accurately hot stamping to a specific position of the cigarette packet.Hologram positioning hot stamping technology is very difficult, not only requires the printing plant to be equipped with high performance, high precision special positioning hot stamping equipment, but also requires high quality special positioning hot stamping anodized aluminum, production process must also be strictly controlled to produce qualified cigarette products.
