1. A photothermographic material having an inherent Dmin and Dmax optical density, comprising:
- a support having hereon one or more thermally-developable imaging layers which are developable to produce an image when the photothermographic material is thermally processed; and
an area disposed along a length of at least one edge of the photothermographic material, the area having an optical density less than the Dmax and greater than the Dmin of the photothermographic material.

Abstract
A photothermographic material having a Dmin and Dmax optical density. The material includes a support having hereon one or more thermally-developable imaging layers which are developable to produce an image when the photothermographic material is thermally processed; and an area disposed along a length of at least one edge of the photothermographic material, wherein the area has an optical density less than the Dmax and greater than the Dmin of the photothermographic material.

16. A method of thermally processing a photothermographic material comprising a support having hereon one or more thermally-developable imaging layers, the method comprising the steps of:
-
exposing an area along at least one edge of the photothermographic material such that, when thermally processed by a thermal processor, the image density of the area will be less than a Dmax and greater than a Dmin of the photothermographic material; and
providing means to transport the photothermographic material to the thermal processor such that the edge is first transported through the thermal processor.

17. A method of forming a visible image, the method comprising the steps of:
-
exposing a first area of a photothermographic material to form a latent image, the photothermographic material comprising a support having hereon one or more thermally-developable imaging layers which are developed when the photothermographic material is thermally processed;
exposing a second area, different than the first area, of the photothermographic material disposed along a leading edge of the photothermographic material such that, when developed, the second area has an image density less that the Dmax and greater than the Dmin of the photothermographic material;
transporting the photothermographic material to a thermal processor such that the leading edge first contacts the thermal processor; and
thermally processing the first and second areas to develop the visible image. - View Dependent Claims (18)
