With the continuous development of the printing and packaging industry in the 21st century, the increasing introduction, addition, and widespread application of food safety and traceability information, high-pixel high 300-700 dpi large-character inkjet printers are increasingly being used in various packaging materials. After introducing the concept of inkjet technology, high-pixel printheads can print two-dimensional codes with large amounts of information, especially variable identification information, compensating for the inability of printing machines to print variable information. These high-pixel machines can print high-quality readable QR codes that can be scanned, providing companies and customers with the convenience of reading information with stable print quality, enabling both supply and demand parties to check their related product information. This facilitates traceability of food safety issues in the future, leaving no place for counterfeit and inferior goods to hide, thus returning a clean environment to consumers worldwide.
In practical applications, large-character inkjet printing is mainly used for the identification of outer cartons and is suitable for various printing materials such as cartons, corrugated boards, wooden boxes, woven bags, etc. It serves numerous industries including food, beverages, pharmaceuticals, building materials, chemicals, and more. The most significant feature of large-character inkjet printing is that the printed character height can reach several tens of millimeters, with strong visibility from a distance. It is particularly suitable for the logistics and warehousing stages for the quick identification and management of product batches, specifications, barcodes, dates, and other information.
Additionally, large-character inkjet printers have the advantages of high speed, stability, and maintenance-free operation. Many devices also support industrial bus or network system access and can interact with upper-level systems such as ERP and MES, achieving real-time data updates and management to meet the needs of smart manufacturing and Industry 4.0. Compared to the traditional label-sticking method, it does not require consumables, saving labor and material costs, and also avoids issues such as label detachment and damage.
By printing variable QR codes, batch numbers, and production information, large-character inkjet printers not only help enterprises achieve standardized management of product identification but also provide technical support for food safety traceability and anti-counterfeiting. Consumers can quickly obtain product information by scanning the codes, enhancing brand trust and user experience.
