Loris,

It sound like there is somthing wrong with your toner.
I have used this formula, and found it works much like Wynn White
describes. The image tones quite evenly, though the shaddows always
look browner as it is toning. I always fully tone (to a purple-black tone)
and the only change I see from print to print is that the toning time
slowly increases as the toner is used up.
