<p>Systems and methods for transmissive optical sensing of media information encoding are disclosed. In addition, print media and methods of making print media are disclosed. One embodiment of an exemplary method, among others, includes, advancing a portion of a print medium through a transmissive sensor assembly, the portion of the print medium having a barcode, the barcode being minimally transmissive of a set of light wavelengths, and the barcode being encoded with at least one type of information corresponding to the print medium; transmitting light at the set of light wavelengths substantially absorbed by the barcode through the print medium; and detecting changes in the light transmitted through the print medium, the changes being produced by the substantially absorptive barcode.</p> |
