QTR-Quadtone RIP

Thanks Roy....but I probably did not make myself clear.  My mention 
of platinum and negatives was by way of introduction.  What I am 
interested in here is making black only prints with the R2400.  The 
articles I have read are really based around other printers and their 
software.  I have not really found much advice on using QTR for black 
only.  I suppose it would be using a powerful program for a very 
simple task but, that said,  it is the perfect way to control black 
only I would think.   I was hopeing to find others who use the R2400 
for black only printing and have the skills to make their own curves 
for different papers.  Sorry if I caused confusion here.  Good wishes

Matthew
