Abstract
The present invention addresses the problem of paper cockle by stretching the paper as it progresses along the paper path through the wet colorant printing station of a hard copy apparatus. The hard copy apparatus uses a paper feed belt system as a paper platen in which the belt or set of belts is splayed along the paper path. Firmly adhering a sheet of print media to the belt, or belts, system, such as by use of a vacuum force, as it travels through the apparatus printing zone, stretches the media orthogonally and particularly in an orientation perpendicular to the paper path.
