You might want to check into this film's characteristics a little further. Orthochromatic line film usually means Ortho Litho film. I've used ortho litho films by manufacturers other than Agfa. They are about the speed of printing paper, or slower. They are designed for half tone work, in other words pure black and pure white with no shades of gray. These films can be processed to give more or less continuous tones using slow working low contrast developers similar to those used for microfilm. Diluted print developer is often recommended for ortho litho film for continuous tones, but I've never had good luck with it. The images come up too fast, resulting in uneven development and excessively high contrast.
