Dry process production and annotation of archival microform records from hard copy

Abstract From the Canadian patent

Abstract of Disclosure Light reflected from hard copy is reduced to microimage size and applied at an imaging and developing station to a dryprocess mask film strip which is photosensitive to the reflected light and which is developed by heat to provide microimaged transparencies therein. Such microimaged transparencies in the mask film strip are transferred in an image transferring station to a dry process microform film which has archival properties and which is sensitive to and imaged and developed by raidant energy above a certain critical value applied thereto through the mask film strip to provide imaged microform records therein which conform to the transparent microimages in the …
