Kodak Duraflo RT Developer Starter is designed to provide moderately fine grain, good process stability, and better resistance to aerial oxidation.
This developer features a hardener to prevent emulsion damage in the first developer tank of a roller-transport processor.
The standard processing recommendations provided produce the maximum improvement in developer characteristics, such as:
- Moderately fine grain
- Good process stability
- Resistance to aerial oxidation.
The alternate processing recommendations will provide advantages to some users who may have systems with high evaporation rates or low utilization. The alternate recommendations use a replenisher and working-strength developer that is 70 percent of the standard concentration.
The replenishment rate is set at a correspondingly higher rate so the net cost per square foot of processed film is the same as with the standard recommendations.
Advantages of the Alternate Recommendations: The higher replenishment rate (143 percent of standard) provides a greater flushing action and keeps the developer tank cleaner.
Development by-products and dissolved silver compounds, which can transfer onto rollers and tank walls, are kept at a lower concentration in the developer tank.
Unlike most developers, this developer provides a more active developing solution at 70 percent of its standard concentration.
This allows a slightly faster machine speed for some films. With some types of film a lower D-min is obtained by using the more dilute developer.
