Abstract
842,718. Photographic contactprinting apparatus. POSCHEL, A. B. Sept. 10, 1956, No. 31790/58. Divided out of 842,717. Drawings to Specification. Class 98(2) The claims are directed to the photographic printing features only of an apparatus which is identical with that of the original Specification 842,717, the claims of which latter are directed initially to features for the uniform spreading of a photosensitive solution on to the surface of a rotatable cylinder, but are extended to include features for application of a design-bearing film on the sensitised surface of the cylinder and exposing the same through a narrow slot during rotation of the cylinder.
