System and method for creating machine-readable codes in combination with other images such as logos

摘要

A process for creating a barcode with an embedded logo considers a printer gamut and divides the printer gamut into multiple regions. A virtual printer gamut is then generated with the colors in bright and dark regions. A target logo image is generated by mapping the virtual gamut to the original logo image. A logo with embedded barcode is produced using the colors specified in the target logo image.

1. A method of creating a barcode embedded logo, comprising:
dividing a printer gamut into a bright reflectance region, a dark reflectance region, and a middle reflectance region using a reflectance threshold and a predetermined minimum symbol contrast; generating a virtual gamut with colors from the bright and dark reflectance regions based on an original logo image by:
selecting a color pair that comprises a first color from the bright reflectance region of the printer gamut and a second color from the dark reflectance region of the printer gamut; andcalculating an average color by averaging the first and second colors of the color pair; generating a target logo image by:
identifying a reference color in the original logo image;selecting an average color from the virtual gamut that most closely matches the reference color; andreplacing each reference color in the original image with a corresponding average color; and producing an embedded logo with an embedded barcode using colors specified in the target logo image.
