1. A printed label or packaging comprising:
a first printed area, the first printed area comprising a combination of i) a first color (S1), and ii) a second color (S2), in which encoded information is provided on said printed label or packaging through modulation of data representing the second color (S2) with max (positive) and min (negative) tweaks;
in which the combination has been optimized by:
determining a color error between data representing third color data (S3) and a combination of S1 and S2,
determining an information modulating error associated with the max and min tweaks; and
minimizing the color error and minimizing the information modulating error in the combination of S1 and S2;
a second printed area including a 1-dimensional or 2-dimensional barcode; and
a third printed area including text information printed thereon.
