Although laser hologram paper has many advantages, but the bar code that can scan cannot be printed on laser hologram paper, because Holographic papers itself is can be reflective, and present barcode scanner is generally infrared ray or laser beam, and both light impinges upon laser Can scatter in holographic papers, it is impossible to scanning.Therefore the bar code that can scan cannot be directly printed in holographic papers.

But, the most perfect along with technology, occur in that the product that holographic effect and bar code combine.Make holography effect at present The bar code of fruit, usually uses gold stamping mode that bar code irons the outer package of product, and the prominent shortcoming of this kind of technics comparing is Bar code is immutable, and this is the fatal defects of gilding technology.A pattern that the bar code of a collection of holographic effect is simply fixing or Pattern, if preparing a collection of variable bar code, needs to prepare many gold stamping versions, owing to gold stamping version manufacturing cost is the highest, makes Long in time limit, give to adopt and prepare holographic effect variable bar shape code in this way and bring the difficulty being difficult to overcome.

Chinese patent CN201120300622.8, discloses a kind of Quick Response Code using transparent ink layer hollow out, though this kind of Quick Response Code So can reach the effect of holographic Quick Response Code, but because the brightness of anodized aluminium is the highest, take pictures inquiry when, have impact on recognition effect.

Along with the most social development, the variable security of product is more and more important, and client does not require nothing more than each piece of mark difference, also Require the aesthetics of mark, at present in field of anti-counterfeit technology, the most do not develop the digital hologram bar that cost is relatively low, easy to make Code.
