Method for preparing camera-ready photostatic copies printed by raster printers for use in the publishing industry

Claim 1

A method for increasing the optical fidelity of the characters printed on a plurality of pages by a raster printer which is coupled to a data processing system which pages are assembled together and photo-reduced, the method comprising the steps, executed with the aid of said data processing system, of obtaining from said data processing system a representation of said page including its width and length dimensions to be sent to said raster printer; expanding said width and length dimensions of said page by a predetermined scale factor; rotating said expanded page 90 degrees; dividing said expanded and rotated page into a first number of subpages, said first number being determined according to said scale factor; and printing each one of said first number of subpages onto separate sheets for later assembly; translating the upper-left hand corner of the expanded page representation to the right by an amount corresponding to the width of said sheets of paper; and rotating said translated page 90 degrees to allow display of said enlarged text across the length of said enlarged page; printing registration marks onto said sheets; assembling said subpage by aligning said registration marks; and photo-reducing said assembled subpages onto a photographic plate or stat.
