The colored circles or small shapes (often called “printer’s color blocks” or “process control patches”) on food packaging are primarily used in the manufacturing and printing process—not for consumers. Here’s what they really mean:
1. Printer’s Alignment & Color Calibration
-
These circles (usually in CMYK colors—Cyan, Magenta, Yellow, and Black) help ensure the packaging design is printed correctly.
-
They allow printers to check if colors are aligned and accurate before mass production.
2. Quality Control for Packaging Machines
-
Some food packaging machines use these marks to detect where to cut, fold, or seal the packaging.
-
Sensors on production lines may read these marks to ensure proper placement of labels or designs.
3. Not Related to Food Safety or Ingredients
-
Despite myths, these marks do not indicate nutritional content, GMO status, or food grade.
-
They are purely for manufacturing efficiency and print accuracy.
Other Common Symbols on Food Packaging:
-
Recycling Symbols (♻) – Indicate the packaging material type (e.g., PET, HDPE).
-
Expiration Codes – Often printed separately (e.g., “Best By,” “Use By”).
-
Certification Logos – Like USDA Organic, Non-GMO Project, Fair Trade, etc.
Bottom Line:
The colored circles are just technical aids for printers and machines, not secret codes for shoppers. Always check labels for actual product info!
