AI Overview
Colored circles found on plastic packaging (like snack bags) are printer's color blocks or process control patches. These marks ensure color consistency during printing and allow operators to verify all ink colors are correct. They are for quality control, not a indicator of product contents or food safety.
- Printer's Color Blocks: These circles (or squares) indicate the ink hues used to produce the package design.
- Purpose: They allow printers to check if the packaging color aligns with the intended design.
