First post!
Starting this group so that optical printer camera operators/lineup people/engineers, company owners, (former or current) can trade useful information about optical printing.
Created initially for customers of my Optical Printer Control Systems (OPCS) software so they can intercommunicate, I thought I'd open it up to all optical printer folks, as the subject matter of printing is fast becoming the way of the dinosaur, and it's harder to find information.
Topics may stray from discussions on techniques for using various printer setups (software, hardware, maintenance), to sales of printers/parts, film stocks used for printing, special effects techniques, recommendations for reading material related to optical printing.
