I recently toned a RC print and there was a distinct sulfiding on the surface in some areas. It looked irridescent and metalic in nature. I had bleached the print for 30 seconds in the bleach component of a two-part Kodak sepia toner, then put the print in Kodak Polytoner. I had done this before with success. What do you think caused the problem on this print?

It sounds like the print still had fixer on it.

Greetings,

Unlike selenium toning which will work on unwashed prints, to produce clean prints with sulfide toning you need a fully washed print, as Scott mentioned. If residual fixer remains in the emulsion, streaks will result when toned in sulfide.
