ABSTRACT:
A method of printing regular photographic prints on a strip of paper along with index prints--that is, prints with images that are smaller than those in the regular prints--from series of negatives on rolls of film. The smaller images are projected next to and one after another along the strip to produce an index print as wide as the strip. The regular prints and the index prints are printed at different points along the strip. The results of area-by-area measurements of the negatives obtained while the regular prints are being printed are exploited to control light quantities while the index prints are being printed. The distance the strip of paper advances from one printing point to the other is regulated to ensure that paper is advanced to the index print printing point once the last negative in a series has been projected onto the strip until the trailing edge of the last print arrives at the margin of the exposure area in the index print printing point. Further printing procedures are discontinued at the regular print printing point until the trailing end of a length of paper that is reserved for the index print associated with that series of negatives, and that must accordingly not be exposed to light, has crossed the edge of the exposure opening near the index print printing point.
