Abstract 990,476. Photographic typecomposing. FILMKLISCKEE G.m.b.H. Feb. 6, 1962 [Feb. 14, 1961], No. 4586/62. Drawings to Specification. Heading B6W. A photographic typecomposing process for the direct production of text-matter comprises projecting with non-actinic light. on to a photographic material, the light-sensitive coating of which is impregnated with a developing solution, the image of the type character to be reproduced, adjusting the position of the character image on the material, e.g. with respect to other characters thereon, and then projecting an image of the character with actinic light on to the material whereby exposure and development are effected simultaneously. Preferably the photographic material is a paper or transparent base film with a light-sensitive coating of steep gradation and low-sensitivity such as a highcontrast silver chloride paper having a large threshold exposure value, the non-actinic light used is red light, and the exposing light is strong white light. The exposed and developed material is finally fixed.
PHOTOCOMPOSING PROCESS FOR THE PRODUCTION OF A PROCESS COPY WHICH COMPRISES THE STEPS CONSISTING ESSENTIALLY OF IMPREGNATING WITH DEVELOPING SOLUTION A PHOTOSENSITIVE BASE HAVING A LIGHTSENSITIVE COATING CONTAINING SILVER CHLORIDE, OF A STEEP GRADATION CORRESPONDING TO A SLOPE OF AT LEAST 45* OF THE GRADATION CURVE OBTAINED BY PLOTTING THE EXPOSURE IN LUX. SEC AS ABSCISSA AGAINST THE DEGREE OF BLACKENING PRODUCED BY SUCH EXPOSURE AS ORDINATE, BOTH IN LOGARITHMIC SCALE, AND OF A SENSITIVITY LOW ENOUGH THAT NO BLACKENING OCCURS UNLESS EXPOSED TO AT LEAST 1.5 LUX. SEC,; PROJECTING A PICTURE OF A TYPE NEGATIVE WITH VISIBLE NON-ACTINIC LIGHT ONTO THE IMPREGNATED BASE; ADJUSTING THE POSITION OF THE BASE WITH RESPECT TO THE LOCUS OF THE PROJECTION OF THE TYPE PICTURE THEREON; THEN, WITHOUT USE OF A LAYOUT, PROJECTING THE PICTURE OF THE TYPE NEGATIVE ON THE BASE WITH STRONG ACTINIC LIGHT; SIMULTANEOUSLY DEVELOPING THE RESULTING IMAGE; REPEATING THE ABOVE DEFINED SEQUENCE OF STEPS UNTIL THE PROCESS COPY HAS BEEN COMPLETED; AND FIXING SAID PROCESS COPY IN A FIXATIVE BATH.
