Problems solved by technology

Jet printing technology can solve the problem of online jet printing, but because the speed of jet printing cannot be synchronized with the speed of the production line, and the recognition rate of the printed 2D barcode is too low, there is currently no feasible technical solution in the world that can solve this problem

Embodiment Construction

[0034] See Figure 5.

[0035] The two-dimensional barcode of the present invention is a two-dimensional barcode composed of a group of 3*2 dot matrix graphic units, wherein the one-to-one correspondence between each dot matrix graphic unit and characters can be set arbitrarily. The entire barcode is a 7×2 structure.

[0036] There is an interval between each column of barcodes, and the interval width is related to the working speed of the production line or packaging line and the printing speed of the inkjet printer. There is a check bit between each row of dot matrix graphic units, and the check bit is also represented by a dot or a dot matrix.

[0037] Figure 6 and Figure 7 show the frame, which is pre-printed, and the two-dimensional barcode is randomly printed in the frame, and the six holes on one side (Figure 6) and the double lines on one side (Figure 7) set on the frame are used to determine the barcode The reading direction indicates the order of reading barcode inf...

Abstract

The invention discloses a system for printing two-dimension lattice hologram graphic code. The system includes one or several bar codes made up of several lattice image units sprayed by code sprayer, there has gap between each line code, the lattice image is formed with dot sprayed by code sprayer, preset lattice image unit is correspondent to different letter. The system sprays bar code in the frame online. The upper and the subjacent part of the left and right ends of the frame have special mark, which is used as the reference point of bar code direction identification.

Description

technical field [0001] The present invention belongs to a two-dimensional barcode, specifically a code printing machine on the production line or product packaging line, along with the manufacture and packaging of the product, simultaneously prints on its packaging or directly on the product a different, unique 2D barcode system. Background technique [0002] At present, the development of one-dimensional barcode technology is relatively mature and common. All general commodities consumed by residents are sprayed with barcodes to facilitate equipment identification. However, this one-dimensional barcode can only be used as an identification mark for specific information, such as representing the item number, to facilitate computer pricing. The same product produced by a manufacturer uses the same barcode, which cannot be distinguished between the same products and cannot adapt to modern times. The need for electronic informatization of logistics management has brought great...
