What are the requirements for the quality of barcode printing?

Regarding the quality requirements of barcode printing, today I will share with you the quality requirements in barcode printing. 1In order to ensure correct scanning and reading, the printed bar code should be neat and clear, with no obvious defects in the bar code, and no excess residual black spots in the blank characters. Usually, the maximum diameter of defects and stains should not be larger than the nominal value of the narrowest bar code.0.4times. 2. Controlling the size error of the barcode is the guarantee of improving the reading rate of the reading device and reducing the decoding error rate. This should not only improve the quality requirements of plate making, printing or printing, but also improve the tolerance requirements of the reading device. 3. In order to read reliably, the bars and spaces in the barcode after printing should have obvious contrast signals. The greater the contrast signal of the barcode, the better the reading performance. 4, The printing tolerance must be strictly controlled during printing, otherwise the effect of reading will be affected. 5, There must be certain requirements for the edge roughness of the barcode. When the roughness is too large, it cannot be read.
