Hey Scott,
I also have printed using OEM Dye Black + MIS VM on my brand new
1280. I did it out of necessity, because the black VM catridge I
received from MIS has a problem with the chip, and my printer would
not recognize it. So, I just threw in the OEM Black that came with
the printer. I have had no previous experience with the 1280/VM
combo. Previously I had used the 1270/VM, but there were no available
curves for the 1270 at that time, so I had tweeked the 1280 curves.
So when I printed with the 1280/OEM Black/VM combination for the
first time, using the Roark 1280 NC curve, I got an excessively
dark, and posterized image. Sometimes, I can get silly enough to
print a image without first testing on a 21 step wedge(!).
Because of this first failure, I decided I would give this whole
thing a fresh look. I decided that I would not subject my image to
any adjustment curve, rather I would force the printer to lay down
ink in the right proportions. So first I printed "straight-as-is",
i.e., no curves, no adjustment. The image was medium warm, a little
too bright in the mid-tones, and a little too dark in the 95% step.
So I corrected this by using a transfer function in the printer
dialogue of 95/92, 90/88. And, I increased image contrast by 5%. The
print, viola, was nice medium-warm, and tonally a very good match
compared to a previous print made with colored dyes on my old 1270.
Then, to print the same image more neutral, I just used the magenta
slider to +12. It worked just fine!
So, I am thinking that the VM inks without curves on a 6 color
printer (4 color also?) is really a tri-tone solution - black, dark
gray (normal+toner), light gray (normal+toner). You control tone by
varying the amount of toner ink (as designed by Roark).
I will send you a print made this way. It is the same image I
submitted for your print exchange, so you can compare directly with
my previous attempt using the dye color inks.
Good luck with your efforts.
