The relationship between inkjet printers, QR codes and product traceability systems
Now, entering the era of the Internet of Things, the development of Internet + QR code technology is rapidly advancing the integration of economic information technology, which provides a great opportunity for product safety supervision and management, the collection of big data, and the establishment of a safety traceability system for imported products such as food. Strong technical support and guarantee. Here, the establishment of a product safety traceability system is inseparable from data collection, product information entry, automatic identification, etc., which rely on a two-dimensional code with large information capacity and rapid identification. Therefore, the generation and direct marking of the two-dimensional code on the product or product packaging, especially the uniquely marked bar code or two-dimensional code of a single product, is particularly important. A unique barcode, two-dimensional code or variable two-dimensional code, directly generated and quickly marked directly on the product or product packaging, requires a high level of identification equipment technology. At present, the methods of direct marking of two-dimensional codes are mainly labeling machines sticking two-dimensional code labels, printing on the packaging by the printing factory, printing by thermal transfer printers, and non-contact ink jet printers or laser jet printers. Wait. The labeling machine technology is relatively traditional. After the QR code generated by the computer is printed out with a barcode printer, it is automatically pasted on the product or product packaging through the labeling machine, which is low in efficiency and high in equipment costs. It is also in the product storage and transportation process. Easy to fall off. Printing two-dimensional codes is only suitable for direct inkjet printing of packaging materials in a printing plant, and the limitations are obvious. Thermal transfer printers Thermal transfer printers are currently one of the effective means to directly print variable QR codes online, but they are affected by installation environment conditions, printing efficiency, etc., and are only limited to some industries or packaging bags and labels. And so on promotion and application. High-resolution two-dimensional code inkjet printer non-contact inkjet printer technology, showing a strong advantage in direct online printing of variable two-dimensional codes, is an important means and method for future product traceability and direct marking. Inkjet technology or inkjet equipment, receive a single unique variable barcode or two-dimensional code generated by the system, or receive the information characters of the two-dimensional code to be produced, convert it into a barcode or two-dimensional code graphics, and print directly Go to the product or product packaging, and then enter the marked qualified product into the system through the inspection and rejection system, so that the data information of the product enters the Internet of Things system, so that the product becomes transparent in terms of logistics and information. Therefore, inkjet printers, whether inkjet printers or laser printers, usher in another spring in this innovative era of Internet + security. Whoever seizes the first opportunity will usher in new development opportunities.
