Digital BW, The Print

Steve,

I haven't printed the EEM profiles recently (I'm working with UT inks 
right now and glossy papers), but most of my profiles show a jump with 
the OffsetGrad image at around 99% to 100%.  I'm not sure how you would 
deal with this or if it is even something to be concerned about as long 
as you are not seeing shadow gradient problems in real life prints.  
Perhaps Roy has some suggestions.  I'd be much more concerned if there 
were distinct bands in the mid tones or quarter tones where they are 
more likely to cause problems in real images with smooth tonal 
gradients in these lighter areas.
