USING QUICK SILVER

The developing agent in QUICK SILVER is pyrazolidone-hydroquinone, which permits very accurate
control of print density, contrast, and color.

COLOR

QUICK SILVER gives B&W print tones a distinctive neutral color which does not vary from
highlight to shadow nor with development time (unlike metol-hydroquinone solutions). QUICK SILVER gives warm-tone papers
a more neutral color than other developers.

CONTRAST & DENSITY

QUICK SILVER develops all images tones at a constant rate. Therefore overall print density increases
with development, but contrast ( the relative difference between highlight and shadow density) does not vary. Overall density may
be controlled by exposure and/or development. Color and contrast are determined only by the type of paper and grade of filtration.

Directions on this label are for processing B&W prints with QUICK SILVER and two other SPRINT™
concentrates. Mix working solution in any volume by diluting 1:9 with water. One liter of QUICK SILVER concentrate will make 10 liters of
working solution, enough to process (600) 8×10 fiber prints or (900) 8×10 resin-coated prints.

EXHAUSTION INDICATOR

When printing with QUICK SILVER Print Developer, BLOCK Stop Bath and RECORD Speed Fixer mixed in equal volumes, BLOCK Stop Bath’s
color indicator will signal the simultaneous exhaustion of all three solutions.

PROCEDURES FOR PRODUCING B&W PRINTS

STEP

PROCEDURE

TIMING

1: QUICKSILVER Print Developer 30 sec – 3:00 min (See EXPOSURE & DEVELOPMENT)
2: BLOCK Stop Bath 5 Seconds
3: RECORD Speed Fixer 1-3 Minute(s)
4: Water Wash 10 Minute(s)

Agitate continuously in all steps. For maximum shadow density, move prints at least
2-3 inches per second through developer.

Drain for 5 seconds between each step. Note: When draining prints, wait until solution draining off of the print has turned from a stream into a single drip.
This procedure will prevent excess solution from entering the other baths and speeding exhaustion.

Solutions may be used at any temperature between 18-30°C / 64.5-86°F.

HOW TO MIX

STANDARD DILUTION

Dilute QUICK SILVER concentrate 1:9 with water to make the desired volume
of working solution.

FOR EXAMPLE:
100ml QUICK SILVER B&W Print Developer Concentrate
+ 900ml Water
= 1000ml QUICK SILVER B&W Print Developer Working Solution

 

ALTERNATE DILUTION

Dilute QUICK SILVER concentrate 1:19 to make a weaker working solution which is economical when printing in large trays or
whenever the full capacity of a 1:9 solution cannot be used. This dilution has a slower activity which is useful when exposure or development of prints cannot
be limited enough to reduce excess density. Minimum Times for a 1:19 working solution are approximately 30 seconds longer than in the 1:9 working solution. The capacity and shelf
life of 1:19 solution are one-half that of the 1:9 solution.

FOR EXAMPLE:
50ml QUICK SILVER B&W Print Developer Concentrate
+ 950ml Water
= 1000ml QUICK SILVER B&W Print Developer Alternate Working Solution

WATER WASHES

Minimum water wash time for commercial purposes is 10 minutes for fiber-based prints, and 3 minutes for resin-coated prints.

For thorough washing to archival specifications, please refer to the ARCHIVAL PROCEDURES described in the instructions for using ARCHIVE Fixer Remover.

EXPOSURE & DEVELOPMENT

Once immersed in QUICK SILVER, most RC prints will develop to their final contrast and color characteristics within a range of 30-60 seconds and then continue to increase in overall density only.
Most Fiber prints will develop to their final contrast and color characteristics within a range of 1:30 – 3:00 minutes and then continue to increase in overall density only. Within five times the minimum development time,
density will increase by approximately 1 full stop in fiber prints or 1/3 stop in resin-coated papers. Development may continue past this point but the density increase will be slight and safelights may fog prints. Development for less than the minimum time will result in flat, uneven density.
Prints which require very long development to reach desired density are underexposed. In most cases it is practical to adjust exposure so that the print develops to the desired density within 1-4 minutes, at any temperature 18-25°C / 64.5-77°F.

CAPACITY & TRAY LIFE

One Liter of QUICK SILVER Print Developer 1:9 working solution will process at least (60) 8×10 fiber prints or (90) 8×10 resin-coated prints.

Deeper solution has a longer tray life. After 12 hours per inch depth of working solution, QUICK SILVER’s activity slows to double the Minimum Development
Time, but contrast and color activity remain the same within capacity.

SHELF LIFE

Stored away from strong light, at a temperature of 25°C / 77°F or lower, QUICK SILVER has the following shelf life:

SHELF LIFE OF CONCENTRATES AND WORKING SOLUTIONS:

CONCENTRATE:

MINIMUM SHELF LIFE:

Unopened Container 12 Months
Opened Container (air free) 6 Months
Opened Container (25% air) 3 Months

WORKING SOLUTION:

MINIMUM SHELF LIFE:

Unused, Full Container 1 Month
Used, Full Container 1 Week
Used, 25% air 72 Hours

Storage for longer times or under less favorable conditions will reduce working solution capacity by 50% or more.
