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)
8x10 fiber prints or (900) 8x10 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 Processing B&W Prints

Step Procedure Timing

1: Quick Silver Print Developer 30 sec - 3:00 min (See Exposure &
Development) 2: BLOCK Stop Bath 5 Seconds
3: RECORD Speed Fixer 1 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 Dilutions

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 Dilutions

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 Archive 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) 8x10
fiber prints or (90) 8x10 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.
