Embodiment 1

[0036] This embodiment provides a method for determining the bar width compensation amount of a one-dimensional barcode, including determining the bar width compensation amount y of k times the module width bar k The steps of , where k is a positive integer, determine y k The steps include:

[0037] Determine the module width n in units of the number of printed pixels and the width kn of k times the module width bar;

[0038] Use a printing device to print a test target with strips of k times the width of the module on the carrier, each test target includes at least two strips and a space, and the strip width a in units of the number of printed pixels k with empty width b k meet: a k k +b k =kn,a k = kn when b k =1;

[0039] By judging whether the adjacent strips in the test target are in contact, find out the critical test target of k times the module width strip, the critical test target is that the adjacent strips do not touch, and the strip width value is a k large...

Embodiment 2

[0043] This embodiment provides a method for determining the bar width compensation amount of a one-dimensional barcode, which includes determining the bar width compensation amount y of k times the module width bar k steps, k is a positive integer.

[0044] This method specifically comprises the following steps:

[0045] S01, set k=1, that is to determine the strip width compensation y of the 1 times module width strip 1 , which specifically include:

[0046] S011. Determine the module width n, and accordingly determine the width kn of the k-times module width bar, and the width of the 1-times module width bar is also n. Among them, n takes the number of printing pixels as the unit (so it is obviously a positive integer), and the printing pixel is the smallest point that the printing device can print. The module width is n, which means that the module width is equal to the connected size of n printing pixels .

[0047] Preferably, the module width n can be determined by t...

Embodiment 3

[0077] This embodiment provides a method for printing a one-dimensional barcode, which includes the following steps:

[0078] Determine the strip width compensation y of the k times module width strip by the above method k ;

[0079] Use a printing device to print a one-dimensional barcode bar on the carrier, and when it is necessary to form a bar of k times the width of the module, use the printing device to print a width of (kn-y k ) of the strip.

[0080] That is, assuming n=5, k=2, y 2 =2, then the required width of the 2 times the module width bar is 2*5=10 printing pixels, at this time, if you want to print the 2 times the module width bar, then instruct the printing device to print the width at the position of the bar: (2n -y 2 ) = (2*5-2) = 8 printing pixels of the strip, after the width of the strip is increased, that is, the width of the closest to 10 printing pixels of the strip.

[0081] Of course, for strips without corresponding strip width compensation (for...

Abstract

The invention provides a method and a system for determining one-dimensional barcode bar width compensation amount, and a barcode printing method. The invention belongs to the technical field of one-dimensional barcode. With the method and the system, a problem of excessive width during current one-dimensional barcode printing, or misidentification of the barcode, can be solved. The method for determining the one-dimensional barcode bar width compensation amount comprises the steps that: a module width and the width of a k-fold module width bar are determined; a test target of the k-fold module width bar is printed; through determining whether adjacent bars in the test target contact, a critical test target of the k-fold module width bar is found; and barcode bar width compensation amount is obtained according to the bar width of the critical test target. The one-dimensional barcode printing method provided by the invention comprises a step for determining the one-dimensional barcode bar width compensation amount with the method, and a step for printing according to the barcode bar width compensation amount. The system used for determining the one-dimensional barcode bar width compensation amount comprises a functional unit corresponding to the method. The method and the system provided by the invention can be used for printing 128-bit barcode and the like.

Description

technical field [0001] The invention belongs to the technical field of one-dimensional barcodes, and in particular relates to a method and system for determining barcode bar width compensation, and a barcode printing method. Background technique [0002] With the development of technology, barcodes (also known as barcodes) are more and more used in commodity circulation, book management, postal management, banking systems and other fields. Among various barcodes, 1D barcodes are most widely used because of their simplicity and ease of use. A 1D barcode consists of a set of spaced, parallel, low-reflectivity rectangular bars; these low-reflectivity bars (eg, black) are called "bars," and the high-reflectivity spaces between bars ( If it is white), it is called "empty". The width of bars and spaces in a one-dimensional barcode is in the unit of "module width", that is, the width of all bars and spaces is an integer multiple (1 times, 2 times, 3 times, etc.) Combinations of ...
