Embodiment 1

[0037] like figure 1 As shown, it is a schematic flowchart of a method for generating a one-dimensional barcode provided in Embodiment 1 of the present invention, and the method may be described as follows.

[0038] Step 101: Obtain experimental image information printed by a multi-grayscale inkjet printing device.

[0039] Wherein, the experimental image information includes the gray level of the color block and the actual printing line width information of the color block.

[0040] In step 101, a specified experimental image is printed using a multi-grayscale inkjet printing device. Among them, the printed experimental images can reflect the actual printed line width information corresponding to different inkjet print heads, different numbers of nozzle holes, and different gray levels.

[0041] Wherein, the number of nozzle holes of the inkjet printing device may be 1 to N, and N is determined according to the maximum line width value required for printing barcodes. For e...

Embodiment 2

[0071] like figure 2 As shown, it is a schematic structural diagram of a one-dimensional barcode generating device provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is an invention under the same inventive concept as Embodiment 1 of the present invention. The generating device includes: Module 11, analysis module 12 and generation module 13, wherein:

[0072] The obtaining module 11 is used to obtain the experimental image information printed by the multi-grayscale inkjet printing device, wherein the experimental image information includes the grayscale of the color block and the actual printing line width information of the color block;

[0073] The analysis module 12 is used to analyze the experimental image information, and obtain the statistical value of the actual printing line width information corresponding to each gray level;

[0074] The generation module 13 is used for inputting the statistical value of the actual printing lin...

Abstract

The invention discloses a method and device for generating a one-dimensional barcode, the main contents of which include: obtaining the gray level including color blocks printed by an inkjet printing device with multiple gray levels and the actual printing line width of the color blocks The experimental image information of the information; analyze the experimental image information to obtain the statistical value of the actual printing line width information corresponding to each gray level; input the statistical value of the actual printing line width information corresponding to each gray level into the barcode Generating software, traversing to obtain one-dimensional barcode dot matrix information, and printing one-dimensional barcode according to the one-dimensional barcode dot matrix information; in this way, it is effectively avoided due to external factors such as printing media, ink and drying environment, and the physical resolution of the nozzle. Insufficient rate leads to the problem of low barcode printing quality, and improves the printing quality of one-dimensional barcodes, especially the printing quality of low modulus one-dimensional barcodes.

Description

technical field [0001] The invention relates to the technical field of one-dimensional barcodes, in particular to a method and equipment for generating one-dimensional barcodes. Background technique [0002] In the field of inkjet printing, due to the limitation of the resolution of the inkjet print head, the printing quality of arbitrary modulus barcodes, especially the printing quality of low modulus one-dimensional barcodes cannot be guaranteed. [0003] In the commonly used barcode generation technology, based on the physical resolution of the inkjet print head, the one-dimensional barcode dot matrix is ​​generated according to the one-dimensional barcode international generation verification method, so that a relatively high-quality barcode in the theoretical sense can be printed. However, in the actual printing process, due to the influence of external factors such as the printing medium, the printing ink used, and the degree of environmental dryness, the quality of th...
