Abstract

A print medium includes a sheet. A plurality of parallel rib elements extend along the sheet and are configured to provide the sheet with anisotropic bending properties.

Claims

1. A print medium that comprises:

an opaque cut sheet; and

a plurality of parallel rib elements extending along the sheet and configured to provide the sheet with anisotropic bending properties so as to provide a flat print viewing surface.

2. A print medium as claimed in claim 1, wherein the rib elements are fast with the sheet as a result of being pressed into the sheet.

3. A print medium as claimed in claim 1, wherein the sheet is layered.

4. A print medium as claimed in claim 3, wherein the sheet includes a pair of layers which are adhered together.

5. A print medium as claimed in claim 4, wherein one of the layers includes the rib elements and the other layer defines a smooth surface to facilitate printing thereon.

6. A print medium as claimed in claim 1, wherein each rib element is of a polymeric material.

7. A print medium as claimed in claim 6, in which each rib element is an extruded element.
