Abstract
Improvements in and relative to printing plates for use in offset printing characterized in that the method producing such plates comprises the production of the original image as a positive image on the face of the fabric of a double sheet of paper having in addition to said fabric a backing sheet fixing said tissue face to one side of said support separating the backing sheet from the double paper by placing the side of the support that carries that tissue in close contact with the sensitized printing plate and directing light through the support that carries the tissue on the sensitized printing plate.
