Two-variable one-dimensional progressive encrypted binary anti-counterfeiting printing method

Abstract

The invention discloses a double-variant one-dimensional progressive encryption binary anti-counterfeiting printing method which comprises the following steps: performing [+++] encrypting operation and channel encoding to binary anti-counterfeiting information to generate a binary modulating signal, and adopting a modulation mode of a looped look-up table method to embed the anti-counterfeiting information into the whole page through sequential change in a shape of amplitude-modulated dot. Therefore, the anti-counterfeiting information can be recognized from any fragment during presswork recognition. The method can be widely applied to the anti-counterfeiting field of presswork.

Description

Technical field:

[0001] The invention relates to an anti-counterfeit printing technology, in particular to a double-variable one-dimensional progressive encryption binary anti-counterfeit printing technology, which can be used for anti-counterfeiting of various printed products. Background technique:

[0002] The existing relatively common anti-counterfeiting methods are as follows: The first is laser anti-counterfeiting marks, which use laser recessive ink fluorescent ink printing technology to print product logos or special identification patterns into product anti-counterfeiting labels. And the same type of product uses the same label, because the anti-counterfeiting label is easier to forge, and the fake anti-counterfeiting label is used on the counterfeit product, causing the product to be confused, so it is difficult to effectively prevent counterfeiting. The second is the password anti-counterfeiting label. The method adopted is to compile a set of numbers for each pr...
