Abstract
Abstract A web of photographic paper is provided with indicia in the form of parallel grooves which are impressed into the rear side of the web by a reciprocable or pivotable ram- or wheel-shaped tool having one or more projections in the form of teeth, ribs or rings. The grooves are deep enough to be detectable by a needle, elastically mounted blade or other mechanical scanning means which cooperates with a transducer serving to produce signals for actuation of a device which severs the web between neighboring prints or for actuation of an evaluating circuit which receives a signal upon detection of the last print forming part of a customer order. The grooves extend at right angles to the longitudinal direction of the web. The projections of the tool can be heated to insure the formation of lasting grooves even if the web is caused to pass through one or more liquid baths before it reaches the scanning station.
