The most popular bar code readers have red light with a 630 nm wavelength. Only prints with the printed code, lines dimensions, and proper overprint contrast allow for the accurate reading of symbols. Both the background color and the color bars are necessary to create contrast. The lines should be the darkest and the backdrop should be as light as feasible. White, yellow, orange, or bright red should be used for the background, and black, blue, green, or dark brown for the lines.
