Problems solved by technology

Two-dimensional codes only increase the vertical arrangement of bars and spaces to expand the information volume of barcodes, but the space for increasing the information capacity of two-dimensional codes in this method is limited and cannot meet the needs of practical applications. The appearance of three-dimensional barcodes solves the problem of barcode information capacity. problem, but the existing three-dimensional barcodes use color as the third dimension, which puts forward higher requirements for printing technology and reading equipment, and traditional barcodes including the existing three-dimensional barcodes are all printed on paper, which is resistant to The damage ability is poor, even if there is a certain error correction (correct reading) ability, it is only limited to the barcode when it is partially damaged

Embodiment 1

[0031] The making material of the barcode label of the present embodiment is a photosensitive polymer, and each height unit of the information storage unit 21 of the design barcode is divided into eight heights (see Figure 4 ), the first height is 000, the second height is 001, the third height is 010, the fourth height is 011, the fifth height is 100, the sixth height is 101, the seventh height is 110, and the eighth height is 111. The difference of each height is 0.1mm, and each height represents 3 bits respectively.

[0032] The three-dimensional solid model of the barcode label is processed layer by layer, and the generated layer format files are format converted to form a series of bitmap files. The series of bitmap files are imported into the three-dimensional barcode inkjet printer layer by layer, and printed layer by layer, that is The three-dimensional bar code label of the present invention is made.

Embodiment 2

[0034] Each height unit of the information storage unit 21 represents 2 bits, and the others are the same as in the first embodiment. Compared with Embodiment 1, the information density of the label in this embodiment is relatively low, and the area of ​​the barcode label expressing the same information is relatively large, so it is suitable for occasions where the requirement for information storage capacity is not high.

Embodiment 3

[0036] Each height unit of the information storage unit 21 is divided into eight heights, but the difference between each height is 1.0 mm, and the others are the same as in Embodiment 1. The height difference of each unit in this embodiment is relatively large, and it is easy to be distorted during the printing process, so it is not suitable for occasions requiring high precision in label production.

Abstract

The invention relates to a three-dimensional barcode label and a manufacturing method thereof. The label consists of a unit matrix, which comprises positioning areas, an information coding area, an initial area and an ending area, wherein the positioning areas are positioned on two opposite borders of the unit matrix, and consist of positioning units, and two adjacent positioning units have different heights; the information coding area is positioned in the middle area of the unit matrix, and consists of information storage units composed of columns with different heights; and the other two opposite borders of the unit matrix are respectively the initial area and the ending area. The method for manufacturing the label comprises the following steps of: 1, converting a data character into abinary bit stream; 2, splitting the binary bit stream into a data segment and an error correcting code field; 3, splitting the data segment and the error correcting code field to form a code word stream of a code word; 4, compiling the code word stream into information storage units with different heights; 5, arranging the information into the matrix according to symbol requirement; 6, generatinga three-dimensional barcode file by using a coder; and 7, manufacturing the three-dimensional barcode label by using a three-dimensional barcode printer.

Description

technical field [0001] The invention relates to barcode technology, in particular to a novel three-dimensional barcode label based on inkjet printing forming technology and a manufacturing method thereof. Background technique [0002] A barcode is a special optical symbol that can be read by optical scanning devices. According to the spatial dimension, barcodes can be divided into one-dimensional barcodes and two-dimensional barcodes. [0003] A one-dimensional barcode is a graphic symbol composed of a set of black and white stripes of different widths. These graphic symbols are arranged and combined according to certain rules (that is, coding methods). They are used to represent a series of numbers, letters and symbol information. Typical one-dimensional barcodes include UPC barcodes, EAN barcodes, and 128 barcodes. One-dimensional barcodes have less information content, so they must be used in conjunction with a database. [0004] Two-dimensional barcodes are just barc...
