Arista Premium Liquid A&B Lith Developer is a two part, non-corrosive, economical developer specifically designed for use with the Lith Printing process of select B&W photographic papers. The liquid is a less active developer than the powder version (item # 50022) and is not recommended for use with Ortho Litho film, but can yield useable results, depending on exposure and developing time.
- For Ortho Litho Film - Mix one part concentrate (A&B separately) to three parts water (1:3), then mix equal amounts of the diluted solutions together in the tray.
- For Lith Printing - Mix one part concentrate (A&B separately) to 24 parts water (1:24), then mix equal amounts of the diluted solutions together in the tray.
When Lith Printing B&W paper, it is important to understand that results are not repeatable - each Lith print is a unique work of art. After each print is made, the makeup of the developer and its reaction to the paper changes. Your developing time, dilution and temperature all affect your outcome.
