Abstract
A media substrate for imaging includes a front and back surface defining a thickness. The front receives imaging fluid and absorbs it. The back has scoring lines extending into the thickness that limit curling of the media substrate as the absorbed fluid dries on the front. Patterns and locations of scoring lines as well as their depth into the thickness are noted. Imaging and scoring stations in an imaging device are still other embodiments as are cutting features for scoring.
Claims8
A media substrate for imaging, comprising:
- a front and back surface defining a thickness, the front surface comprising imaging fluid that is absorbed into the thickness, the front surface being devoid of score lines;
- and
- a plurality of score lines cut on the back surface that extend between 10% and 50% into the thickness and arranged such that the back surface has lesser stress than the front surface to reduce curling of the media substrate as the absorbed imaging fluid dries.
