QTR-Quadtone RIP

I am sorry Tom, but your words do not inform me.  I have made 
numerous prints of step wedges and actual photos in attempts to 
puzzzle out the meaning of Toner and Toner2.

When I take on a new computer routine I attempt to explore all the 
functions or alternatives offered; how can I know what may be useful 
without trying when there is no pressure to achieve specific results?

Thank you for your attention.  As noted in my last missive, I have 
employed Toner and Toner2 as you suggest.  No benefit.  For the 
present, I shall abandon whatever utility Toner and Toner2 may 
represent.
