With ZONALPro, you get:
 GAMMA
Plus is a highly concentrated developer formulated to provide
maximum processing flexibility under normal, plus or minus developing
procedures. Compatible with monosized, t-grain, and conventional
halide emulsions, GAMMA Plus provides excellent acutance, fine
grain structure, and extended tonal separation in both shadow
and highlight details. Film speed adjustments and tone value
placements are achievable and predictable through variations
of processing time, temperature, or developer concentration.
GAMMA Plus is suitable for tray, tank, or machine processing.
SMALL
TANK DEVELOPMENT
35mm Roll Films, Initial Developing Times (Min.) @ 68°, Intermittent
Agitation.
Temperature
Range: 60° F to 90° F
 FACTOR
One is a high concentration, PQ type print developer formulated
to produce optimum results with both graded and
variable contrast papers. It provides extended tonal range control
and is adaptable to the techniques and image desires of the photographer.
FACTOR One is flexible in both dilution ratio and development
time. This buffercd and sequestered solution provides extended
capacity and good tray life with minimum oxidation.
USE
RECOMMENDATION:
Due to variations in sensitized materials, equipment and processing, testing is encouraged to establish the optimum conditions for a given paper type.
Temperature
Range: 55° F to 100° F
 HQ
WARM TONE is a concentrated, true warm tone developer containing
no METOL and has been formulated to produce optimum results with
both graded and variable contrast warm tone papers. It provides
full tonal range control and is adaptable to the techniques and
image desires of the photographer. HQ WARM TONE is
highly flexible in both dilution ratio and development time.
HQ WARM TONE has been formulated with buffering
and sequestering agents to provide extended capacity and a very
good tray life with minimum oxidation.
USE
RECOMMENDATION:
Due to variations in sensitized materials, equipment and processing, testing is encouraged to establish the optimum conditions for a given paper type. · FULL TONAL RANGE WARM PRINT DEVELOPER
 ZONAL Pro® EC RAPID Fixer is an
extended capacity (EC) fixer designed to minimize emulsion wet
times, promoting both efficient archival washing and conservation
of the amount of wash water needed to produce image permanence.
ZONAL Pro®
EC RAPID Fixer will achieve complete removal of residual silver
halide from a print in 30 seconds or less and is formulated for
efficient and rapid negative fixing while providing the solvent
effect needed for the removal of dye components from film emulsions.
ZONAL Pro®
EC RAPID Fixer is suitable for tray, tank, or machine processing.
USE RECOMMENDATION:
**Frequent and rapid agitation during the fixing cycle will assure removal of red/pink dye components.
 ZONAL
Pro® Fixer Hardener is a high capacity fixer additive designed
to enhance the surface durability of all photographic emulsions.
When used with ZONAL Pro® EC RAPID Fixer, it will minimize
abrasions in processing, handling, and storage while promoting
the rapid drying of both films and papers. ZONAL Pro® Fixer
Hardener does not contain formaldehyde.
ZONAL Pro® Fixer Hardener is suitable for tray, tank, or
machine processing.
USE RECOMMENDATION:
Temperature
Range: 45° F to 75° F
 A
highly concentrated washing agent which assures archival permanence
while reducing wash water consumption and washing time of negatives
and prints by 80 to 90%. The solution speeds the removal of residual
fixer and silver-sulfur compounds from emulsions and paper base
fibers, minimizing processing wet time while preserving print
brilliance and contrast. ZONAL Pro® Archival Rinse can also
be used as the dilution medium for Selenium Toners to help achieve
archival permanence of the toned image.
USE
RECOMMENDATION:
Agitation during the Archival soak is recommended. Both 1st and 2nd wash require a minimum water flow volume of 1.5 gallons per minute to assure archival permanence levels in compliance with ANSI IT9. 1-1988.
Temperature
Range: 45° F to 75° F
 ZONAL Pro®
Indicator Stop Bath provides effective process control through
its immediate and complete termination of development and neutralization
of development alkalinity, extending the capacity of the fixing
bath. Its high concentration prevents staining and the formation
of mineral deposits on negatives or prints. The solution will
change to a visible purple color to indicate exhaustion when
developer carry-over causes the pH to exceed 6.8. A mild citrus
scent has been added to the concentrate to minimize the acidic
darkroom odors normally associated with stop bath solutions.
