How does inkjet date coding work on snack food products?

Inkjet date coding has become popular in the food industry to print expiration dates and lot numbers.
Here’s how it works:
Preparation: First, the snack food product preparation by ensuring it is clean and dry. This ensures that the ink adheres to the surface of the product correctly.
Ink selection: Second, a compatible ink selection based on the substrate (surface) of the product. Food-grade inks can ensure that the ink is safe for consumption and meets regulatory requirements.
Set up: Third, set up the inkjet printer with the appropriate ink and the desired information in the printer software. This can include expiration dates, lot numbers, barcodes, and other important information.
Printing: Forth, Once the printer setup is completed, it uses a high-pressure system to spray tiny droplets of ink onto the surface of the snack food product. This creates the desired text or image on the product, which consumers and other stakeholders can easily read.
This helps to differentiate products and create brand recognition among consumers.
