1. A system comprising:

  • an input to receive a design file, the design file comprising an image including an area of layered colors, the image comprising luminance or chrominance values;

    one or more multi-core processors and a memory storing instructions that, when the instructions are executed by the one or more multi-core processors, cause the one or more multi-core processors to function as;

    a blend module for operating on the design file, the blend module generating reflectance spectra estimates for the image including the area of layered colors, the reflectance spectra estimates provided on a per pixel basis for the design file;

    a signal detector to determine whether the design file includes a signal encoded therein;

    a signal encoder for encoding a signal in the image to yield an encoded image, in which the signal encoder encodes the image only when the signal detector finds no signal encoded within the design file, the signal encoder transforming the image by introducing positive or negative adjustments in units of the image, with each unit representing a plurality of pixels;

    a visibility module for generating visibility information associated with the encoded image, and for reducing visibility of the encoded signal in at least one area of the image;

    a mask module for evaluating the image on a unit level to determine whether the luminance or chrominance values, prior to encoding, falls within a predetermined luminance or chrominance range, and for compressing or eliminating the positive or negative adjustments when the luminance or chrominance values fall within the predetermined luminance or chrominance range, the mask module producing a masked, encoded image.
