Liquid Chemistry
For Black and White Films and Prints
STANDARD is the basic film developer in the SPRINT B&W processing system. All solutions for this process are in liquid concentrate form. One liter of STANDARD concentrate will make 10 liters of working solution, enough to develop at least (50) rolls of 35mm 36 exposure film, or enough replenished solution to develop 110 rolls. Directions provided here are for basic negative processing.
Dilute STANDARD concentrate 1:9 with water to make the desired volume.

TIMING |
| 1: | Water Pre-Wet | 1 Minute(s) |
| 2: | STANDARD Film Developer | See DEVELOPMENT |
| 3: | BLOCK Stop Bath | 1 Minute(s) |
| 4: | RECORD Speed Fixer | 3 Minute(s) |
| 5: | Water Pre-Wash | 1 Minute(s) |
| 6: | ARCHIVE Fixer Remover | 3 Minute(s) |
| 7: | Water Wash | 5 Minute(s) |
| 8: | END RUN Wetting Agent & Stabilize | 1 Minute(s) |
| 9: | Sponge Squeegee & Dry |
For each step listed above, agitate continuously for the first MINUTE and for 10-15 seconds of each MINUTE thereafter. During development (step 2), if development time is less than 6 minutes, agitate continuously for the first MINUTE and for 10-15 seconds of each HALF-MINUTE thereafter. When development time is less than 3 minutes, agitate continuously. Use only enough solution to cover reels, leaving an air space for thorough agitation with bubbles.
Wash films with a complete exchange of water (empty & refill) three times per minute, even with automatic washers.
1 liter of STANDARD 1:9 working solution will develop 400 square inches of film. Example: (5) rolls of 35mm 36 exposure or (5) rolls of 120 film. With replenishment as directed, 1 liter of working solution will process ten times this amount of film.
To renew a volume of working solution which has been used to capacity, add STANDARD concentrate to the working solution in the following proportions:
FOR EACH: |
ADD: |
|---|---|
| 10 ² in sheet film | 1.0ml concentrate |
| 35mm, 20 exposure roll | 4.5ml concentrate |
| 35mm, 36 exposure or 120 roll | 7.5ml concentrate |
This replenishment returns the working solution to its fresh working condition and capacity. When replenished developer is used to capacity it may be replenished again, repeatedly, until a total of 4000 square inches has been developed per liter.
