Re: haunted VDB

Hi Loris,
They faded a little.
Each print is in a plastic sleeve.
I washed the prints well, no yellow stain and no citric acid either.
Final wash was 25 min in running water.
Hang to dry.
I have 1998 VDBs that are fine, this is the first time it's happening.
Thanks for the inputs, I'll try citric acid.

Are the prints also fading along with changing color? If they're also fading
I'd suspect the porfolio and/or a mistake in processing. Have you cleared
and washed well the prints? Do you notice a yellow stain (most notably when
looking under a bluish fluorescent light?

See my procedure below:
1. Wash 2 mins in 2 separate baths of dilute citric acid (a dessert spoon to
2000ml water)
2. Gold tone (optional)
3. Fix for 2 mins. in 2% plain sodium thiosulfate
4. Wash for 15 minutes chaning water at least 5 times.

No problems with untoned (yet!) and toned prints as old as 6 years so far...

Hi Cor,

No treatment other than normal processing and washing.

Did you gold tone them?

Hi Folks

After printing really brown prints with traditional formula on arches
aquarelle and archiving them in a portfolio, some prints changed from
brown to gray.
They were perfect 20 days before.
Does anyone know what might be happening?

Thanks in advance,
