Digital BW, The Print

Hi. I am a fine-art black and white printer in Milan where I have a
lab where I want to start printing with an ink jet printer with carbon
inks for my clients (fashion, architecture, reportage, art photograpers). 

My problem is micro-banding. This is what I use: Epson Stylus Pro 7000
plotter; Mis Ultratone inks; samples of different papers (Epson
Enhanced Matte, Arches, Hanhemuhle Photo Rag). I have followed the
instructions in the Mis web site for the cleaning procedure with the
Mis cleaning cartridge set, I have installed the ink cartridges and
started the Epson purging procedure. After four tests, when I printed
the purging test pattern, I have micro-banding only on the full black
part. I have done the Epson software procedure for re-alignement and
nozzle cleaning and the problem remains. Now, I have no more ink and,
in order not to waste to much money in tests, I am thinking about
buying continuous flow inks. I am a bit disappointed. Before buying
these inks, I would like to ask you where the problem can be. In the
paper? In the inks? In the plotter hardware? 

Thanks a lot for your help. 

Gianni

Are you using QTR or a Paul Roark curves style workflow?

There's a bug in QTR that causes microbanding, it's firing one nozzel
off, i.e. it might lay down black with 79 black nozzels and one light
black nozzel, instead of all 80 black. I don't know if it happens with
all printers, but it's definitely visible with the Epson 2200 in
2880DPI mode.

I am not using QTR, but the Paul Roark workflow for Epson 7000 or
7500. Do you know something about it? 
Thanks for your answer.
