A method for optimally using color patch codes or color barcodes for transmitting machine-readable information, via device characterization, is disclosed to comprise characterizing a printing device and optionally a sensing device for identifying a number of recognizably spaced printer output colors; deriving a code book, by relating the printer output colors and their corresponding input values to information elements; and using the code book for encoding and decoding the information to be transmitted. The recognizably spaced printer output colors are in terms of a color space relevant to a color patch code or color barcode sensing device, and are related to the corresponding marking device input values.
