KODAK PROFESSIONAL HC-110 Developer is a highly concentrated liquid developer. It is intended for use with a variety of black-and-white films.
Highly active - Short development times
Liquid concentrate - Easy mixing
Clean solution - Cleaner tanks, racks, and reels; less equipment maintenance
Long solution life - Fewer chemical dumps; less waste
Stable solutions - Easy process control, even with low utilization
Quality of stock solutions - maintained over a long. Good shelf life
DILUITION: You can prepare HC-110 Developer working solutions by diluting stock solution or concentrate. Mix either stock or working solutions at a temperature between 10 and 32°C
Stock solution: To prepare stock solution, dilute one part concentrate with three parts water.
Working solution: three parts water. To prepare working solutions, dilute stock solution or concentrate according to the following tables.
Note: Take care when measuring the concentrate, because of its viscosity. Follow these recommendations for handling. Pour the concentrate slowly to avoid air bubbles. To simplify measuring small amounts, use a positive-displacement method such as a cylinder accurate or a syringe. Mix the solution for several minutes until the concentrate is fully dissolved.
DEVELOPMENT TIMES if film is properly exposed, the times in the following tables should produce negatives with contrast suitable for printing with a diffusion enlarger (or by contact) on a normal-contrast black-and-white paper. If printing negatives with a condenser enlarger, decrease the development time by approximately 30 percent to produce lower contrast. development time. If your negatives are consistently too dense or high in contrast, decrease the development time; if they’re too thin or low in contrast, increase the development time. The following tables offer starting-point recommendations. Adjust as needed.
STORAGE: the table below provides guidelines for storing unused solutions at 18 to 24°C (65 to 75°F). The storage temperature is important as higher temperatures cause solutions to oxidize rapidly.
