Orwocolor 5168 process & formulae

[Domin]

The formulae are from quite old book using old polish chemical substance names and in some cases it wasn't easy to look up as most resources on the web use new names. I used mainly wikipedia as source for translation of the names. I think I double checked but please read carefully.

The process is for Orwocolor NC21 but the book I have states it is also ok for older NC19.

Process 5168
Color develop (C14) 6-8min 24C +-0.25
Stop (C37) 2-5min 20-24C
Wash 4min 21-24
Bleach (C55) 4min 22-24C
Wash 4min 21-24
Fix (C71) 5min 22-24
Wash 8min 21-24
Wetting (F905 1+200) 0.5min 20-24
Dry max. 40C

Process 5168/1
Color develop (C14) 8-10min 21C +-0.25
Stop (C37) 2-5min 20-24C
Wash 2-5min 20-24
Bleach (C55) 5min 20-24C
Wash 5min 12-21
Fix (C71) 5min 20-22
Wash 15min 12-21
Wetting (F905 1+200) 0.5min 20-24
Dry max. 40C

Times are given for constant agitation.

Steps from both variations of process can be combined.

I haven't found formulae for F905 and I do not know if it is just wetting agent or if process needs formaldehyde stab.

I know it's an old thread I'm bumping, but I would just like to say thank you, as I've been looking for this specific recipe for some NC19.

Also I assume the developer is to be watered to 1000mL?

Created in 2008, bumped in 2014, bumped again in 2018. That is vintage.

Also I assume the developer is to be watered to 1000mL?

Your assumption is correct.

I have the "Orwo Rezepte" (collection of Orwo formulae) 1983 edition in German. If there are any questions, feel free to ask.

User georgegrosu knows everything about this process, having processed many rolls in romania. I think he also has experimented using alternate chemistry. Write him.

Some serious necromancy here. Funny thing, I've recently returned to photography after a long hiatus and the first forum page I've here checked has a ten year old thread with my name on it. What are the chances? And I just might be doing some orwocolor in near future.
