Summary
If the barcode scannercannot scan well , the first thing that comes to mind is definitely a quality issue, so let's not go into detail. Firstly, it is possible to analyze the quality of the printed barcode and observe it with the naked eye. Those who use a scanning gun know that barcodes are mostly composed of black and white, while one-dimensional codes mainly consist of black and white bars. In fact, two-dimensional codes can also be said to be black and white bars and black squares.

Those who use a scanning gun know that barcodes are mostly composed of black and white, while one-dimensional codes mainly consist of black and white bars. In fact, two-dimensional codes can also be said to be black and white bars and black squares. It is possible to check whether the black part is clear. If there are white spots in the black part or some black parts are not, it indicates that the quality of the barcode is not good, Some scanning guns with good performance can read, while others with average performance may not be able to read.
The tightness issue of barcodes is that barcodes are usually printed on the surface of labels or parts due to limitations in area size. Sometimes, when the barcode is too large and the label paper is too small, operators may shrink the barcode during printing, which can result in the barcode being unable to be scanned.
The density of barcodes, each barcode has a density, and some high-density barcodes require high-precision scanning guns to be read. If the precision of the scanning gun is lower than the density of barcodes, then barcodes cannot be read.
