Last night I tried making some prints on Kentmere Kentona using heated LD20 - 30ml of A+B to 1350ml of water, no old brown, heated to about 28C - when I took a look at it in white light the whole sheet of paper had a yellowish brown tone to the whole print including the unexposed borders. I lowered the temperature of the developer added some old brown, mixed up some fresh Agefix and tried again. This time I had a fleshy pink tone including the borders and some pepper fogging (I suspect the old brown was at fault). I've used Kentona for lithing before (same box) without a hint of trouble.
Does anyone have a clue as to where I might have gone wrong?
