• Complete Barcode Masking: The original EAN, UPC, or ISBN barcode must be completely covered so scanners never pick up the wrong code.
  • Edge Margins: Labels must have at least 0.25 inches (6mm) border spacing from package edges and folds.
  • Flat Placement: Applied smoothly on the most accessible flat surface without creases or tears.
  • Thermal Printing: High-density thermal transfer printing that does not smudge, fade, or rub off during transport.
