Embodiment Construction

[0024] Such as figure 1 As shown, the invisible graphic recognition system includes a printed matter 1 and a digital identifier 2 matching it. On the surface of the printed matter 1, there is a density pole formed by digitally processing invisible graphic texts with a plurality of hidden graphic texts. High digital dot matrix 3; print 1 adopts transparent or translucent or opaque materials.

[0025] When the corresponding digital identifier 2 is covered on the surface of the printed matter 1, the human eye observes the graphic and text of the printed matter 1 through the tiny lens, and the hidden graphic and text appear. The concealment and appearance, depth and shallowness of the text are in a state of alternating and gradual changes. When different digital identifiers 2 are covered on the surface of the same printed matter 1, different images and texts of hidden marks can be displayed.

[0026] When the printed matter 1 is made of transparent or translucent material, the d...

Abstract

An invisible graphics contex identifying system and fabrication method thereof is to numeric-code process, deompose, respectively set the secret-mark graphics context on the surfaces of numeric code identifier and presswork, presenting an invisible graphics context. There are a purality of combined minute lens of particular focus. When the numeric code identifier is covering on the particular location of surface of corresponding presswork, the invisible graphics contex appears. The graphic context may produce progressive, alternate, dynamic change of invisible and visible, dark and light. A plurality of numeric code identifier may correspond to the surface of single presswork to present different invisible graphics context. It has the advantage of directviewing, convenience, and anticounterfeit, and it can be used to anticounterfeit of certificate, document, banknote, stamp, commodity, package, etc.

Description

technical field [0001] The invention relates to an anti-counterfeiting measure and device for pictures and texts, in particular to an identification system for invisible pictures and texts and a manufacturing method thereof. Background technique [0002] In recent years, people have used various means to resist counterfeiting, such as laser anti-counterfeiting labels and three-dimensional anti-counterfeiting labels. Therefore, people are always seeking better fidelity anti-counterfeiting technology. [0003] In the existing anti-counterfeiting technology, a specific combination of parallel stripes at different angles is used to form invisible graphic prints, and the slight visual difference of different reflectivity formed by stripes at different angles to light is used to observe invisible graphics, or use The 180-degree parallel stripe grating recognizer is covered on the invisible graphic print, using the interrelationship between the stripes of the recognizer and the st...
