The inkjet printer prints variable barcodes on the carton, what are the problems that need to be paid attention to

In the carton packaging industry, inkjet printers are often used to print variable information such as serial numbers and production dates on the outer packaging. At present, the inkjet printer can realize the identification of three kinds of two-dimensional codes, such as a variety of common one-dimensional bar codes and QR codes. However, in practical applications, we still need to pay attention to some potential problems that may occur when barcode printing on cartons: 1. The commonly used material for packaging cartons is mesh corrugated paper, which is different from ordinary white paper. On corrugated paper, we need to pay attention to the reflectivity of the paper. , Which will affect the recognition of barcodes. 2. When selecting ink for inkjet printers, high-performance inkjet inks with good color fastness, low permeability and moderate ink dispersion should be used to ensure the high quality of barcode inkjet printing. 3. When printing barcodes on corrugated cartons, pay attention to the problem of scale accuracy. The appearance of the cartons may not be completely flat, may be uneven, and the force may be uneven during transportation, which will cause the barcode to bend and deform. The barcode should be used to ensure the accuracy. There is a certain fault tolerance scale. 4. Bar codes have strict requirements on the bar-to-space ratio. Therefore, it is necessary to ensure the stability of the production line speed. If the production line speed is changed, the length of the printed content will be changed. Regarding the text content, the length change will generally not affect the misreading, but Bar code printing, the change of bar code length will change the bar space share, resulting in unrecognizable bar code. If the stability of the transport during the printing process cannot be ensured, a synchronizer should be equipped to ensure that the printing speed is synchronized with the production line speed. 5. Before printing barcodes in batches, a barcode printing test should be carried out to ensure that the barcodes can be scanned and read correctly. Because it is necessary to use special equipment to read the barcode, it is necessary to check the correctness of the barcode content before batch production to avoid human errors. In the process of inkjet printing, spot checks should be made regularly. It is necessary to ensure the accuracy of the bar code printing of the inkjet printer, and ensuring that the bar code can be quickly and correctly scanned and recognized is the key to the code assignment on the carton. Therefore, our operators must pay attention to this point during the marking process.
