Abstract:
A method for reducing cockle of print media in a wet dye hard copy apparatus having a vacuum platen, the method comprising:transporting the media along a paper path to a print zone of the apparatus superjacent the vacuum platen; transporting the media along a continuing paper path through the print zone while printing on at least a downstream region of the media in the print zone; substantially immediately following printing on the downstream region of the media, bending the downstream region having wet print thereon along at least one predetermined radius of curvature such that high frequency cockle of the print media is substantially eliminated, the bending including bending the media having wet dye thereon along a predetermined first radius of curvature such that cockle amplitude is reduced; and following the bending the media, rebending the media having wet dye thereon along a second radius of curvature until the wet dye is substantially dry.
