QUICK SILVER Print Developer

Makes 10 liters of working solution, enough to process (600) 8×10 fiber prints or (900) 8×10 resin-coated prints.

The developing agent in QUICK SILVER is pyrazolidone-hydroquinone, which gives very good control of print density, keeping contrast and color constant.

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 image 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 SILVE concentrate will make 10 liters of working solution, enough to process (600) 8×10 fiber prints or (900) 8×10 resin-coated prints.

Procedures for Producing B&W Prints

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 the print has changed from a stream into a series of drops. This procedure will prevent excess solution from entering the other baths and accelerating exhaustion.

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