ABSTRACT:
A process for thermally developing a photothermographic media within an enclosed processor comprising the steps of transporting a photothermographic element with a latent image thereon to a thermal heating element comprising a rounded heating element such as a drum, placing said photothermographic media with a latent image into contact with said drum, heating said photothermographic media with a latent image thereon with said drum to generate a photothermographic media with a visible image thereon, then removing said media with a visible image thereon, said process comprising venting gas from at least two separate areas within said processor, said at least two areas including a first vent at a position above the axis of the heating drum, and a second vent at a position sufficiently near a point on the drum where the photothermographic media with a visible image thereon is removed from the drum so that at least some vapor material leaving said photothermographic media with a visible image thereon exits through said second vent.
