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

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

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

17. A method of forming a visible image in a thermographic imaging apparatus, the method comprising the steps of:
-
thermally imaging a first area of a thermographic material to form an image, the thermographic material comprising a support having thereon one or more thermally-developable imaging layers which are developed when the thermographic material is thermally imaged by a thermal imager;
thermally imaging a second area, different than the first area, of the thermographic material disposed along a leading edge of the thermographic material such that, when thermally imaged by the thermal imager, the second area has an image density less that the Dmax and greater than the Dmin of the thermographic material; and
transporting the thermographic material through the thermographic imaging apparatus such that the leading edge first contacts the thermal imager. - View Dependent Claims (18)
