Digital BW, The Print

Hi all,

Yesterday, my sample carts of MIS VM-sepia arrived, my very first 
foray into the world of black and white injet printing! I installed 
them into my 1280 and downloaded the MAC curves from the MIS site. I 
first tried printing with the vmm8-w.acv curve which should give a 
neutral print. My test print showed a lot of posterizing. Some cloud 
detail for completely disappeared. When i tried the slightly warm 
curve, vmm8-mw.acv, I did not seem to have this problem. The effect 
is noticeable on the monitor as soon as the curve is applied. When 
the vmm8-w curve is applied, clouds disappear and other parts of the 
image start to look weird, not so with the vmm8-mw curve. I havn't 
printed with the other curves yet, but when I apply then, the image 
looks reasonably OK on the monitor. I tried another image, a nude, 
and had similar results, with strong posterization during the 
transition of skin tones going from dark to light, as well as in the 
sky. What can i do? I am a real novice at this, I have set up my 
printer according to the instructions on the MIS site, photoshop 6 
set up according to the information on Ian Lysons web site and I am 
printing on epson matt paper.

thanks,   mike
