- pavel_lishin 14y agoI would be worried about yellow inks fading into white.
- pattern 14y agoNo one ever said yellow :) Cyan/Magenta/Green or any other trio of darker and differentiated colors may be able to do the trick.
- rm999 14y agoGood idea, but that may introduce some really thorny issues with color calibration.
- mjn 14y agoAlso, potential data-corruption issues with color laser printers that add spurious yellow watermarking dots [1], though perhaps a sufficiently robust error-correction scheme would be able to work around that.
