Abstract
Prints of film frames forming part of relatively short film strips are made by attaching to each film strip a tab, inserting the strip and the tab into an envelope which bears information denoting the order number, the number of prints to be made, the type of prints, and customer identification, shipping or delivering the envelopes to a processing laboratory where the information which is borne by the envelopes is encoded on the respective tabs, grouping the envelopes and film strips according to the nature of prints to be made and the type of film strips, reproducing successive or selected film frames of a group of strips by imaging them onto a web of photographic paper in a copying machine without splicing the film strips together, subdividing the web into discrete prints, assemblihg the prints with the associated envelopes and film strips for delivery or shipment to customers, and calculating and recording the cost of each order.
