EC JET laser inkjet printers use a high energy density laser beam to burn the surface of an object, creating a permanent mark. Its operating principle involves multiple complex processes, including laser generation, laser modulation and control, laser focusing and

scanning, and material interaction.

EC JET laser inkjet printer introduces: Application of laser inkjet printer in food labeling.

1. Production date and expiration date coding: Accurately and clearly printing the   production date and expiration date on food packaging helps consumers understand

the freshness and shelf life of the food while also meeting regulatory requirements. For example, laser inkjet printers can accurately print the production date and expiration

date on the packaging of bottled beverages, bagged snacks, and other foods. This

information is permanent, high definition, and difficult to tamper with or wear out.

2. Batch number and traceability code printing: Each batch of food is printed with a

unique batch number and traceability code, enabling full traceability from production

to distribution. When quality issues arise, these codes can be used to quickly locate the production link and distribution path of the problematic product. For example, on the

packaging of foods like cooking oil and rice, laser printed batch numbers and

traceability codes can help companies and regulators track the source and destination of products, ensuring food safety.

3. Brand and trademark inkjet printing: Print food brand logos and trademarks on

packaging with high precision laser inkjet printing to enhance brand image and

product recognition. Well known food brand trademarks can be clearly and accurately printed in prominent locations on food packaging using a laser inkjet printer,

enhancing the brand's visual impact and market competitiveness.
