ABSTRACT:
A non-film requiring method for applying information to a light sensitive emulsion coated lithographic printing plate comprises obtaining the information applied to a sheet of paper based material, wherein the sheet applied information is essentially opaque to light emanating from a light source and the sheet of paper based material is generally transmissive to the light, positioning the information applied sheet on the printing plate to cover at least a portion of the emulsion, and exposing the sheet covered printing plate to the light thereby directly transferring the information to the printing plate without the necessity of film.
