Hello,
Does anyone happen to have any experience with the development of Technical-Pam using a Jobo processor? I’d need the development times for Neofin paper and the speed of the film for this combination.
I’d also be grateful for any other tips on this subject, of course.
Best regards, Sven.

:huh:
Hopefully this post from the Dutch Fotoapparatuur.nl forum will help:
Although I’ve never used this film myself, I might have the
information you’re looking for.
Kodak Technical Pan Pro
ISO 25 – Rodinal – dilution 1+100 – development time at 20°C: 6 mins.
ISO 25 – Technidol bottle up to 470ml – time at 20°C: 12 mins.
For both combinations: extremely sharp and fine-grained; red light is rendered lighter.

I hope this helps you.

Kodak Technical Pan
ISO 25 - Rodinal - dilution 1+100 - time at 20°C 6 mins
Furthermore, SPUR appears to have developed the Dokuspeed for this purpose. This is being discussed on various forums.
Packaging in 3 x 50 ml.
I myself work with the Agfa Copex in combination with SPUR Nanospeed. ISO 25 to ISO 40.
Very sharp yet with nuanced grey tones.

Best regards,
Robert

25 ISO
Technidol
Use once
Mix carefully (just before use); must be used within a few hours to 1 day
Develop carefully; do not shake too vigorously, etc.
Technidol is specially designed for Technical Pan

I’m happy with the result. I used Rodinal (mainly because of availability, as you have to order Technidol separately in Eindhoven). Thanks for your tips!

Hello Sven,
It’s been a while since I processed TP on half-tone film, so I’m going from memory:
The starting point for tilt-and-turn development is the ‘20 rule’, i.e. 20 minutes at 20°C for 20 DIN (i.e. ISO 80) with a 1-minute tilt. Problems included streaks and uneven density gradients at the edges of the image. A 3-second tilt is much better, and reducing the time to 15 minutes (Durst condenser).
For the Jobo processor, I’d use stage II for testing and develop for about 7 minutes at 20°C.
As the TP has a clear base, it appears to have higher contrast in the negative than it actually does when printed.
Nevertheless: I gave up processing TP after a few years, as the grey tones are truly underwhelming and the edge sharpness isn’t exactly top-notch either, due to the lack of grain.
Good luck

Hi Robert, Hi Mik,
First of all, thanks for the tips; I think I now have a starting point for developing using the rotating method that I can work with. I’ve actually still got a few rolls of TP in the freezer, and I wasn’t particularly keen on developing by hand using the can. I didn’t get any streaks, but tilting the can caused quite a lot of foam to form. I think it’s easier in the rotary process and will give it a go soon.
For Robert:
I reckon I can read the article, even though I learnt my Dutch from the cornflakes, custard and other food packaging that was always on the table when I was on holiday. But linguistically, that’s not really a problem over there, as people are always quite nice and make an effort when you’ve got a problem. Bedankt?! That’s how you say it, isn’t it?
Regards, Sven.
