USING STANDARD

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.

HOW TO MIX

Dilute STANDARD concentrate 1:9 with water to make the desired volume.

FOR EXAMPLE:
100ml STANDARD B&W Film Developer Concentrate
+ 900ml Water
= 1000ml STANDARD B&W Film Developer Working Solution

PROCEDURES FOR PROCESSING B&W NEGATIVE FILMS

Use all solutions at the temperature selected for DEVELOPMENT

STEP

PROCEDURE

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

AGITATION

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.

WATER WASHES

Wash films with a complete exchange of water (empty & refill) three times per minute, even with automatic washers.

CAPACITY & REPLENISHMENT

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:

PROPORTIONS FOR REPLENSIHMENT:

FOR EACH:

ADD:

For each 10²in of sheet film (4×5=20²in) 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.
