Digital BW, The Print

I installed the MIS variable tone inks in my Epson 1160 printer (used 
with a PC and Crane Museo paper)and downloaded the Roark curves for 
that printer yesterday. Before installing the inks I used the MIS 
cleaning cartridges out of an abundance of caution since the black 
inks I'd been using weren't Epson inks. In making my various color 
settings in Photoshop and in the printer dialogue boxes I've followed 
to the best of my ability the 11 footnotes that are underneath the 
Printer/Curve/Paper/Mode table on the MIS web site for these inks, 
which are pretty much identical to the setttins stated in Mr. Roark's 
message #570 posted to this group on August 10, 2001. I've also tried 
each of the four curves and played around with most of the Photoshop 
color settings and properties settings, making changes of one sort or 
another and then Epson dialogue box print settings in an effort to 
get something resembling a decent print. I've also cleaned the 
nozzles and checked the alignment of the printing cartridges. 
Regardless of what I do, only the darkest areas print, there are no 
midtones or highlights. Some look slightly better than others 
depending on what I changed but none except the first two that I made 
look anything like a decent print (the first two weren't great but at 
least they kind of looked like a photograph).  The prints actually 
look almost exactly like line prints (i.e. all black and white, no 
grays, and the white is just the paper white with no detail). I 
thought at first that only the black ink was printing but the 
cartridge level in the Epson dialogue box shows that the color inks 
actually are depleting faster than the black ink so I assume they 
must be going somewhere. I'd suspect a problem with my printer except 
that I was making very nice prints using the standard Epson color 
inks and a third party black ink, with no special curves, immediately 
before installing the MIS inks and the Roark curves. If anyone has 
experienced a similar problem, I'd appreciate hearing from you. I'm 
going to call MIS this morning but thought I'd post this here too in 
case MIS is unable to help. Thanks in advance. Brian
