Abstract
The present invention pertains to a method for preparing a printing form from a photosensitive element by thermal treatment, wherein a gas jet emitting from a nozzle assembly impinges the exterior surface of the element to smooth or polish and mitigate marks and deformations that can be generated during development. Impingement with a heated gas jet provides surface polishing from rapid and specific convective heat flux to the exterior surface of the printing plate.
