Digital BW, The Print

Is this a possibility?  I've just been accepted for a solo exhibition and I am needing a high 
quality BW printing option.  I've considered the 2200 with QTR, as I can just utilize the 
epson carts and print color when needed.

Unfortunately, I rarely print larger than 6x9 and commonly print 4x6 so I need a high level 
of resolution to match my wet prints.  Accordingly, the 2200 would be a large chunk  of 
cash to print 4x6's.

I've used and sold a C86 with the EZN inks.  I am a mac user, and for some reason the 
driver did not provide acceptable results.  When used with a mac, I would get something 
similar to banding - but it was as if the printhead was scraping the paper.  With a PC, I 
never could make this happen.  Also, I've used and closeted an HP 7660 with the #59 
cartidge.  It's a good system, but the premium plus matte paper has a distinct white color 
base that I find unacceptable.

So, I've tried it all.  I like the capabilities of the R800, but would like to make a neutral BW 
print on matt papers.  It seems the red and blue carts will provide an excellent color 
mixing option for QTR, but has anyone tried it?  As the R1800 is coming, I'm sure this 
combination will be highly successful.

Thanks in advance,
Don
