I tried with hypo fixer, and I was able to wash the prints clean of the pink after a long time. It is kind of annoying trying to figure out what the final look of the print is going to be when it is so highly color. Have you guys had the same experience?
The only time I had any color problems was when I overtoned them in concentrated Kodak RST. They turned a bilious magenta. But in the plain hypo fixer they were a gorgeous warm black. Always.
