Running RA-4 in a Jobo Autolab

[Cybertrash]

Hi folks,

The photoclub I'm a member of recently got a Jobo ATL-1000 up and running to everyones excitement, most will use it for C-41 and E6 (myself included), but personally I'm also very interested in producing colour prints from negatives, but I can't quite wrap my head around how I would do that with the ATL-1000. Has anyone got experience doing RA-4 processing in a Jobo ATL-1000 or 1500? My main concern is that the machine spits out the chemistry after each run, which seems to mean that you'd have to mix new chemistry after processing each print, which to me seems like it'd be a huge waste of time when doing test strips and so on. Am I missing something here?

The AutoLab ATL-1000 - good as it is - is mainly a film processor. Jobo processors like the CPP and CPA models can accomodate larger tanks than the Autolabs and are better suited to run the RA-4 process. Reclaiming chemicals is possible on the Jobo ATL-1000/1500, but with a high risk of cross-contamination. I don't think that it is practical to use the TL-1000/1500 to process colour prints.
