My print turn blue!

Hi everybody

I don't know what happened. I did some prints yesterday and everything was fine. New batch of Dektol, fix TF-4 almost new. All of my prints were OK but some hours later, one of these turn bluish with some pink spots. I suspect there is something wrong with the fix but the others prints are always OK this morning.
So what's wrong?

Test the print for residual silver with either Kodak ST-1 or KRST 1+9. If the spot is anything other than a barely perceptible beige color then the print is insufficiently fixed.

Thank you. I'll do it.

norm123,

A little more information would be helpful. What paper are your using, how long are you fixing, etc. A picture of the affected print would help too. FWIW, I've never seen a print turn blue from inadequate fixing; it usually goes yellow-brown. Contamination from minerals in your water is another possibility.

Best,

Doremus

The print is in the garbage. I used demineralized water to make the revelator (Dektol 1+2) and my fix (TF-4). My paper was Arista Edu FB. I fixed...I think 1 minute in 2 baths like usual. No stop bath, a good rinse before fixing. The others prints in the same batch are still good since 2 days. So, I printed since 30 years and I never see a print like that. I can find the print in the recycling bin and I'll put a picture of it toomorow.
