Small character inkjet printer and pesticide label QR code
1. Pesticide traceability. The traceability management of pesticide products in the form of electronic information code labeling is not new. At first, some foreign companies used digital codes and barcodes (one-dimensional codes) to manage their products in order to prevent cross-stocking in the market. In order to strengthen the safety management of paraquat products, a company once carried out traceability management of new paraquat formulations, using QR codes. This is an earlier production case of using QR codes for pesticide traceability management in China. Compared with digital codes and bar codes, two-dimensional codes have obvious advantages such as large information capacity, wide coding range, strong fault tolerance, high decoding reliability, and encryption. Article 24 of the 'Administrative Measures for Pesticide Labels and Instructions' The traceable electronic information codes shall be marked in the form of two-dimensional codes... The format and generation requirements of the traceable electronic information codes shall be separately formulated by the Ministry of Agriculture, and the Ministry of Agriculture has subsequently formulated supporting 'Regulations on the Management of Pesticide Label QR Codes.' Digital codes and barcodes cannot be used due to the lack of supporting documents and standards such as industry management format and generation requirements. The two-dimensional code is currently the only marking form of the pesticide traceable electronic information code. 2. Code position and label form Article 22 of the 'Regulations on the Administration of Pesticides' shall be in accordance with the provisions of the State Council’s agricultural authorities, with the name, formulation, ... traceable electronic information code and other content of the pesticide in Chinese. The pesticide can be seen The traceable electronic information code (two-dimensional code) belongs to the content of pesticide labels, and its labeling should comply with the requirements of the pesticide 'Pesticide Labels and Instructions Management Measures'. Article 3 of the 'Administrative Measures for Pesticide Labels and Instructions' The term 'labels and instructions' as used in these Measures refers to all descriptions on or attached to pesticide packages that use words, graphics, and symbols to explain the contents of pesticides, which can be seen in pesticide packages The outer surface of the object can be marked with the content of the pesticide label as required, and of course it also includes a traceable electronic information code (two-dimensional code). It can be understood that in addition to the traditional label, the two-dimensional code marking position can also be marked on other positions of the package, such as the cap, body, or bottom of a bottled product. Common pesticide packaging mainly includes bottles and bags. Bottled labels are either directly printed on the outside of the packaging, or affixed to the packaging after printing. They are cut into individual labels, and rolls are called roll labels. Common labels are paper and shrink film. The bag label is basically printed directly on the packaging bag, and the packaging bag has two types: forming bag and roll film bag. 3. Pesticide traceability electronic information code (QR code) for coding equipment is one code for one item. The QR code on each label is different and unique. This is different from traditional printing. How to print the QR code To the label, a separate link and identification equipment are required. At present, there are many types of marking equipment on the market. The common ones are: small character inkjet printers, laser inkjet printers, high-resolution inkjet printers, thermal transfer inkjet printers, thermal foam inkjet printers, UV inkjet printers Machines, etc., different equipment has its own characteristics, providing a variety of options for different packaging forms, label forms, different materials and different coding forms of pesticide products.
