PCT No. PCT/US88/00005 Sec. 371 Date Jun. 10, 1989 Sec. 102(e) Date Jun. 10, 1989 PCT Filed Jan. 4, 1988 PCT Pub. No. WO88/05561 PCT Pub. Date Jul. 28, 1988.A process for producing a reversed image proof from a negative film separation (66) including applying a uniform toner layer (60) to an offset member (46), exposing a charged surface (20) through the film separation (66) to produce unexposed non-image areas (68) and exposed image areas (70) thereon, contacting the offset member (46) to the charged surface (20) to transfer toner (74) from the offset member (46) to the surface (20) in the non-image areas (68), leaving an image residue (76) upon the offset member (46), and contacting the offset member (46) to a receptor (49) to transfer the image (76) thereto. The process may be repeated for subsequent colors to produce a positive multicolor image and may also be adapted to conventional proofers formerly capable of producing images from positive film separations only. |
