Abstract
Print media, when rolled tightly often produces a high degree of curl when removed from a roll form. The stiffer the media, the more likely the tendency to curl. On the other hand, print media that is too thin will be too floppy for conventional handling. The print media described is constructed from fine ribs of greater stiffness running along the axis of a roll. These ribs ideally have a pitch of approximately 200 microns and they can be either formed from embedded fibre of greater stiffness or through ridges of greater thickness. The ribs result in material of greater stiffness across the width of the media than along the length and maintain adequate stiffness for handling and viewing of the printed media.
