Well, anyone who uses Fuji paper can pitch in. My RA-4 process is 30 sec pre-wash, 50 developer, 60 blix and 2 min RA-rinse. After my pre-wash, the water comes out blue. If this is final large print, the water comes out really blue. That is even before any chemical is poured in.

The last time, when I processed the test strips, I skipped the final 2 min rinse stage. And the test prints came out with the un-exposed part blue, just the same color as the new paper, just lighter. And the edges where the prints attached to the print drum had darker color (blue). It apparently that the test prints were not washed/rinsed properly. So the original blue coating is still on the paper. The un-exposed paper should came out white, just as I had it many times before....
