Jobo CPP-2 Processor for Film and Prints

The Jobo CPP-2 and CPA-2 Processors are very similar. They both provide lab-quality processing of film and prints. Both use a recirculating water bath to temper the chemicals, and both have the same maximum capacities.

These processors are designed for advanced amateurs and small labs.

The differences between the two processors:

  • The CPP-2 has a cold-water solenoid to allow you to either cool the process down below room temperature, or to quickly lower the temperature of the water bath (i.e. changing from a C-41 process at 38°C to an RA-4 process at 35°C).
  • The CPP-2 uses an integrated digital thermometer which allows it to hold the temperature of the process to within + 0.1°C.
  • The CPA-2 uses a different temperature probe which holds the temperature to within + 0.2°C. This is really only an issue with the C-41 process.
  • It's much easier to set the temperature on the CPP-2. You program the temperature using three knobs for the tens, ones, and tenths of degrees. With the CPA-2, you dial in the temperature with one knob, then tweak it a little after the temperature stabilizes.
  • The CPP-2 displays the water bath temperature on a digital LED readout. The CPA-2 comes with a traditional color thermometer. Back to Top

There are primarily three important variables when developing film and prints. The three are time, temperature, and agitation.

When developing black and white film by hand without a processor, you change the development time based on changes in room temperature.

With black and white film, there is a set formula (for a given chemical developer/dilution) that dictates any increase in temperature will result in a decrease in time, and vice-versa.

The CPA-2 and CPP-2 Processors use a water-bath to ensure even tempering of the chemicals, and the tank or drum that contains the exposed paper or film.
You don't need to install the CPA-2 or CPP-2 in a darkroom. Once the lids are closed on the tanks, they are completely light-tight.
The CPA-2 and CPP-2 are relatively compact machines (for machines that are capable of developing 20x24" prints). They have a footprint of 38x15" (LxW).
The CPA-2 and CPP-2 use a contained system whereby chemicals are only exposed to the air during very short delivery times which cuts down on odors and oxidation.
One processor is used to develop 35mm, 120, and 220 roll film, as well as up to 18 sheets of 4x5" film, and prints up to 20x24".
