How to Use Expired C41 Colour Paper

[L'Image]

Hi Guys,
I have just discovered two boxes of 50m rolls of colour paper., that I forgot I had stored away.
The first one is a Kodak Ektacolor Plus N 50.8cm x 50m, and the second is a Fujicolor Crystal Archive MP 76.2cm x 50m.
The Kodak is probably about 20 years old and the Fuji at least 12years. I have tried printing on both and they have a pinkish base to them instead of the pure white.
I was wondering if anyone know what filtration I could use to flash these in order to get a nice workable print from these.

If the base itself comes up pink, there is no cure in filtration. This is fog. And for that, there is little hope. You might try Benzotriazole or Sodium Bromide. The first, you might try at 10 - 100 mg / L in the developer and the latter at about 0.5 - 1 g/l. There is no guarantee.

Thank You PE for the prompt response.
The darkroom I use has one of those processing machines that you feed the prints through and collect the dried print at the output. I therefore have no control on the chemistry in the machine.the rest of the print looks very crisp except for those pink whites, which is why I was wondering if there was a possible filtration that could just act as an opposite for the pink. I have had prints done for me by professional printers in the past where they have flashed the paper and managed to get these rather lovely pastel feels in the prints.??
I thought if it was possible to do something like that I could make the most of the paper and embrace the colour. I am loathe to throw away such expensive paper......

The ways that I know require manipulation of an open tank or tray of developer. Sorry.

Even flashing for some purposes requires access to the developing sheet.

Hi PE,

Would you kindly share your knowledge on how to flash the paper using the developing tray.
Many Thanks.

Expose normally.
Tray develop for 2 minutes at 68F.
At 1 minute into development, turn on a light (room, flashlight, safelight or whatever suits the effect you wish) for about 15 seconds (depending on the light intensity).
Continue processing in the dark as normal.

There you have it. Examples of a series can be found in my gallery. There are several threads on this and many examples here.

I'm sure there is a market for prints with pink instead of white highlights in the wonderful world of Lomography purists!?!...

Thanks a bunch PE. Will give it a go and maybe share the results.


Lol... Terry. You never know it might catch on and be the next new trend....

I should mention that you will need to make a significant adjustment in filtration, but that will be obvious from the onset.
