Which barcode scanners can scan 3mil and 4mil barcodes?
As we all know, bar code types are not only one-dimensional, two-dimensional, but also low-density and high-density. The bar code density is mainly 1mil, 2mil, 3mil, 4mil and 5mil. The smaller the number, the higher the density. The common one is the latter three. One. In fact, in the actual manufacturing and commodity circulation industries, 3 mil and 4 mil bar codes are rarely used, because it is too small, and the printing process is high, and a carbon ribbon thermal transfer printer exceeding 600 DPI is required. In order to barely print clearly, not all barcode scanners can scan 3mil and 4mil barcodes.
According to industry experts, bar code scanners have their own scanning accuracy limits. Barcode scanners with high precision can be backward compatible and scan some low-precision bar codes, but it is not the higher the scanning accuracy, but the better. The bar code scanner with the corresponding resolution should be selected according to the bar code density used in the specific application. In use, if the resolution of the selected barcode scanner is too high, the stain on the stripe, deinking, etc. may also cause the barcode scanner to be unsuccessful in reading.
Commonly used bar code scanners on the market are generally 3Mil, 4Mil and 5Mil. The resolution of 5mil is approximately equal to 0.13mm, and the resolution of 3mil is approximately equal to 0.08mm. Generally, the scanning spot is the minimum width of the strip. 0.8 times or so is more suitable. In the case of a general product barcode with a magnification factor of 0.8, the minimum strip size is 0.26 mm. The accuracy of 3Mil is higher than that of 4Mil and 5Mil. The higher the scanning accuracy, the more expensive the corresponding barcode scanner is. When purchasing a barcode scanner, the scanning accuracy is suitable.
At present, there are so many brands of barcode scanners on the market, and the price ranges from a few hundred to thousands.
