Problems solved by technology

In other words, it must spend a huge amount of money to replace the decoding equipment (hardware) that captures images for thousands of supermarkets at home and abroad before any manufacturers can use its technology
[0008] Furthermore, in the above-mentioned patent application "Specific barcode based on color background and its forming method", when superimposing grayscale information, although a monochrome digital printing machine or a monochrome inkjet printer can be used, because the length direction of the bar is 100% It is grayscale, and its recognition rate is high, which leads to the reduction of the barcode level
Practice has proved that: when the length direction of the bar is 100% gray, the above-mentioned patented technology - "specific barcode based on color background" cannot be accepted by users due to its low level
In other words, the most widely used one-dimensional product barcode laser scanners in supermarkets at home and abroad are difficult to recognize "specific barcodes based on colored backgrounds" whose length direction is 100% gray

Embodiment 1

[0046] figure 1 , Figure 4 As shown, the standard size of the current commodity barcode, that is, the one-dimensional barcode (3) is 37.29mm×26.26mm, and the magnification ratio is 0.9-2.0. When the printing area permits, you can choose a magnification above 1.0 to print a one-dimensional barcode⑶.

[0047] In order to make the commodity barcode described in the national standard GB12904-2003, that is, a one-dimensional barcode shared by tens of thousands of products (3)—fixed information, it can also imply logistics codes, lottery codes, traceability codes, etc. that are unique, Variable data unique to each product (5)——variable information. Such as figure 1 As shown, some light-colored line segments (6) representing variable data (5) can be printed on some bars (1) in the one-dimensional barcode (3) according to some custom rules, so that the originally pure black bars (1) can be transformed into Segmented bars that are spliced ​​by black and gray segments ⑴. The ref...

Embodiment 2

[0069] like figure 2 shown in figure 1 On the basis, two light-colored line segments ⑹ are added to the 10-billion-digit bar ⑴, so that one bar ⑴ has three light-colored line segments ⑹, so the length of the light-colored line segment ⑹ (or the top position Coordinate number Y) and its quantity can be combined and calculated, expressed as the number 3. Add another light-colored line segment ⑹ on the ten-thousand-digit bar ⑴, so that one bar ⑴ has two light-colored line segments ⑹, so the length of the light-colored line segment ⑹ (or the coordinate number Y of the top position) and Their quantities can be combined and expressed as the number 3. Of course, one of the light-colored line segments (6) can also be used as a check code.

[0070] The rest of the steps in this embodiment are the same as in Embodiment 1.

Embodiment 3

[0072] like image 3 As shown, a bar (1) representing tens of billions of digits can be divided into ten equal parts (middle section) according to the order from bottom to top, that is, divided into 10 module units, and each equal part (module unit) 1mm, the light-colored line segment ⑹ represents 0, and the dark-colored line segment ⑷ represents 1, then the maximum binary code capacity of the ten positions on one bar ⑴ is 2 10 , that is, 1024 combinations.

[0073] In this way, one EAN-13 code has a coding capacity of 1024 to the power of 13 variable data (5), which is of course an astronomical quantity, which can fully meet the needs of one code per piece of global commodities.

Abstract

The invention provides a two-in-one commodity barcode which comprises a one-dimensional barcode printed on an object and consisting of bars and gaps which are arranged. The bars are divided into deep-color line segments and light-color line segments. The positions, or / and the number, or / and the lengths of the light-color line segments are converted into variable data including a commodity traceability code after being recognized by light-color line segment decoding software. The two-in-one commodity barcode avoids color digital printing, is suitable for monochromatic printing, can reduce equipment investment, can increase production speed, can reduce manufacturing cost, and it is not required to replace conventional laser scanner hardware. The commodity barcode of a commodity using the two-in-one commodity barcode has two functions including a commodity barcode and a traceability code.

Description

technical field [0001] The invention belongs to the technical field of one-dimensional commodity barcodes, in particular to a two-in-one commodity barcode containing variable data. Background technique [0002] Commodity barcodes are barcodes specified by the International Article Numbering Association (EAN) and the Uniform Code Committee (UCC) to identify commodity codes, including EAN commodity barcodes (EAN-13, EAN-8) and UPC commodity barcodes (UCC-A , UCC-E) and other commonly used one-dimensional commodity barcodes. The commodity bar code described in the national standard GB12904-2003 of the People's Republic of China is a one-dimensional bar code composed of multiple bars (modules) and multiple bars (modules) arranged in parallel. [0003] Current 1D barcodes (such as Figure 5 shown) is a mark composed of a set of regularly arranged bars, spaces and corresponding characters. The reflectivity of bars to light is low, and the reflectivity of spaces to light is high. ...
