Embodiment 1

[0033] Such as figure 1 As shown, the multi-point coding superposition technology of the present invention includes: printing ink 4, original bottom figure 1 , dot code interference layer 2 and effective dot code layer 3, the printing ink 4 generates the original bottom figure 1 , point code interference layer 2 and effective point code layer 3; the effective point code layer 3 covers the original bottom figure 1 ; The dot code interference layer 2 covers the effective dot code layer 3; the printing ink 4 includes common ink and special ink.

[0034] The normal ink contains only one dot-coded layer, the original base figure 1 And point code interference layer 2 does not contain K value, and effective point code layer 3 contains K value; The CMY value interval of described point code interference layer 2 is [93,100], effective point code layer 3 ideal The range of K value is [90,100].

[0035] The carbon element in the K value in ordinary ink can absorb infrared rays, while...

Embodiment 2

[0037] The specialty inks contain multiple layers of dot-coded layers, the original base figure 1 The dot code interference layer 2 does not contain the K value, and the effective dot code layer is printed separately in layers using special inks that can absorb wavelengths.

Abstract

The invention provides a multi-point coding-superimposing technology which comprises printing ink, an original base drawing, a point coding interference drawing layer and an effective point coding drawing layer. The original base drawing, the point coding interference drawing layer and the effective point coding drawing layer are generated by the printing ink; the effective point coding interference drawing layer covers the original base drawing; and the point coding interference drawing layer covers the effective point coding drawing layer. The multi-point coding-superimposing technology achieves that point coding multi-superimposing can be achieved, coding can not be copied, printing is not damaged, and appearance of the prior presswork is not influenced. Because a coding-superimposing mode is adopted, multi-point coding can be superimposed on the base drawing of the prior presswork. Specific cyan, magenta, yellow, black (CMYK) values of each drawing layer are set, and therefore coding is prevented from being copied.

Description

technical field [0001] The invention relates to a dot code printing technology, in particular to a focus code superposition technology. Background technique [0002] At present, the mainstream coding methods on the market are bar codes and Q-R codes. Only one layer of codes can be printed on the surface of the printed matter, and the codes printed in layers cannot be correctly identified, let alone prevent the codes from being copied. [0003] The use efficiency of traditional printed matter is low. Users can only express content by reading text and pictures, and cannot timely reflect text and picture information through audio and video information anytime and anywhere. With the popularization of computers and networks, printed matter has begun to develop in the direction of multimedia digitization. The use of multimedia printed matter is as follows: print two-dimensional light codes on printed textbooks, select a page to be read, and use the point code recognition device t...
