Cat number for KODAK EKTACOLOR RA Developer Replenisher RT

Domin · Mar 18, 2011

I'm looking for cat number for KODAK EKTACOLOR RA Developer Replenisher RT 4x5l. I can't find it anywhere on the net.

I'm not looking for cat number for RT/LU version, which I know is 529 2396.

As KODAK EKTACOLOR RA Developer Replenisher RT/LU in my experience does not work with Supra Endura VC and Fuji CA in trays and the names are so similiar I need the cat number to check if I can order it locally.

What is the problem with the RT/LU developer? Maybe I can help.

OTOH, I might be able to find the RA/RT developer replenisher # here somewhere.

We allready discussed the issue:

(there was a url link here which no longer exists)

Since that I tried Fuji CA and the results were similiar - mottle, bad DMax, and blue cast in shadows so I guess it's not shot paper.

From what I've seen on Kodak site only the RT version in recommended for use in trays, and RT/LU is recommended only for roller transport:

So we did! Over 6 months ago. Sorry, I forgot.

Ok, here is the Cat # for a 10 L kit (A + B + C) taken from the bottles ...

841 5580

I'll bet that number is obsolete though.

AG Photographic sells or sold 529 2396, and I have used it in trays at room temperature for both Kodak Supra Endura and Fuji CA paper with absolutely no problems. However, I haven't tried Endura VC. And now I remember that thread of yours some time ago. Did you hear back after sending paper samples?

And, what makes you think that the another developer would work? Have you tried higher temperature? It will be cumbersome, of course, but for testing to narrow down the problem it won't take too long.

In the end I did not send the samples.

Which Fuji CA did you use? Plain CA? I think there is half a dozen CA types.

And, what makes you think that the another developer would work?

Honestly, its hope. I have a big stack of negs and I see no reasonable way of finishing the project other than printing optically and developing it myself.

I tested development at about 38C and the result both with Kodak RT/LU and Tetenal chems gave me same bad results. I have not tested Supra Endura but both work fine with old Supra III.

Again, I repeat, Supra III is so old it is nearing the end of its lifetime unless frozen.

But, again I repeat that if at 38C you get mottle, something is probably wrong and you should contact Kodak! I hope that with the 38C process you used a prewet before development and a stop bath after development. These are mandatory with 38C processing.

I think it's "plain" CA. I have bought it a few years ago. I have to check. I know that Fuji's naming system is even more confusing than Kodak's .

I found that, compared to Kodak Supra Endura, it differs in filtration about 5 units in M and Y, and in speed maybe about 1/3 stop or less. And it produces a little bit more saturation and "punch", but otherwise is very close to Kodak.
