1. 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 thereon one or more thermally-developable imaging layers which are developed when the photothermographic graphic material is thermally processed;
exposing a second area, different than the first area, of the photothermographic material to form a second latent image different from that in the first area, the second area disposed along the entire length of a leading edge of the photothermographic material;
the area extending up to 25 mm from the leading edge;
such that, when developed, the second area has an image density less than the Dmax and greater than the Dmin of the photothermographic material;
exposing a third area, different from the first and second areas, of the photothermographic material to form a third latent image different from those in the first and second areas, the third area disposed along the entire length of a side edge of the photothermographic material such that, when developed, the third area has an image density of about Dmax 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, second, and third areas to develop the visible images.

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.
