Abstract
This invention pertains to a method and apparatus for thermally developing a photosensitive element, and particularly to a method and apparatus for supporting the photosensitive element with a removable flexible support member during thermal treatment.
Claims15
A method for forming a relief pattern from a photosensitive element having an exterior surface and containing a composition layer capable of being partially liquefied comprising:
- supplying a development medium to the exterior surface with a first member;
- supporting the photosensitive element with a flexible support member removably mounted on a base member to deliver the photosensitive element to the development medium;
- heating the exterior surface to a temperature sufficient to cause a portion of the layer to liquefy;
- and
- contacting the photosensitive element with the development medium to allow at least a portion of the liquefied material of the composition layer to be absorbed by the development medium.
