Curl resistant media
View Patent ↗A curl-resistant planar media comprises a plurality of fibers embedded in the media and configured such that the media has a stiffness in a first direction that exceeds the stiffness in a second direction that is perpendicular to the first direction.
1. A digital camera print roll of curl-resistant planar print media, the planar print media having a surface on which an image can be deposited by printing and/or photographic imaging comprising:
a planar film treated to have a periodic rib structure wherein the ribs are disposed at a pitch of approximately 200 μm such that the print media has a stiffness in a first direction that exceeds the stiffness in a second direction that is perpendicular to the first direction.
2. A print media according to claim 1 wherein the planar film comprises a plastics material.
3. A print media according to claim 2 wherein the periodic rib structure is formed by extrusion.
4. A print media according to claim 2 wherein the periodic rib structure is formed by pressing the media between two rollers.
5. A print media according to claim 2 wherein the ribs are configured substantially parallel to the longitudinal axis of a roll direction of the media.
