Workflow tips
Contents & Yield
What’s inside?
Color Developer (CD) Part A/B/C, Bleach-Fix (BX) Part A/B, Stabilizer (SB).
Available in two variants: 1.2 L (6× 240 ml) and 2.5 L (6× 500 ml) – all parts in uniform bottle sizes.
How much does one kit process?
With optimal tank capacity and multiple use of the baths:
- up to 18 films (1.2 L)
– up to 40 films (2.5 L)
in 135-36/120 format.
Note: Actual capacity depends on tank load, agitation, and intermediate rinsing.
Temperature control: 38 °C standard, 30 °C alternative
Target temperature
Standard: 38 °C. Alternative: 30 °C (with longer processing times). Both profiles are included in the manual.
Accuracy
For the Color Developer (CD): maintain ±0.5 °C of the target temperature throughout development.
Bleach-Fix (BX) and Stabilizer (SB) are more tolerant (±1–2 °C) – but the rule applies: the more precise, the more consistent the results.
Keeping temperature stable – three methods
- Water bath (basin/cooler/sink): preheat, insulate well, reheat if necessary.
- Sous-vide stick: automatically keeps the water bath at the target temperature; widely available (kitchen/electronics stores, online).
- Rotary processor (e.g., JOBO): heated jacket bath + constant agitation → maximum consistency, ideal for series processing.
Practical tips
- Preheat chemistry, tank/drum, and water bath.
- Check CD temperature right before pouring in.
- timer as soon as the developer reaches the film.
Preparing working solutions (scaling made easy)
Mixing steps
Clear tables for 250 / 300 / 600 / 1200 / 2500 ml make scaling easy. With uniform bottle sizes for each part, there’s less need for conversion – but precise measuring (graduated cylinder) remains essential.
Keeping it clean
- Follow the order and quantities exactly as in the manual; dissolve thoroughly without creating foam.
- Use low-lime water whenever possible (demineralized water if needed).
- Observe the minimum fill level of the tank/drum and avoid air bubbles.
- Label clearly (date / volume / “fresh” vs. “used”).
Stop bath: when it makes sense
Purpose & place in the process
Optional stop bath between CD and BX: immediately halts development and reduces carryover into the Bleach-Fix.
Recommendation
For stable series with multiple reuse, recommended from the third run onwards. With one-shot use or up to two runs, usually not necessary.
Practical notes
- After the stop bath, rinse briefly (as specified in the manual), then proceed to BX.
- Work consistently: use the same times and agitation per batch to minimize drift.
Storage & Shelf life (concentrate & working solution)
Concentrates
Unopened: approx. 24 months. After opening: CD up to 3 months, BX/SB up to 6 months (store cool, dark, tightly sealed).
Working solutions
- Freshly mixed: CD 6–8 weeks, BX/SB up to 24 weeks.
- In use: CD 2–4 weeks, BX/SB up to 12 weeks.
Storage tips: Keep bottles as full as possible (minimize air), store cool & dark; use protective gas if needed. Replace if you notice unusual discoloration or loss of performance.
