Digital BW, The Print

> 
> Hi folks,
> 
> I have been working for the past three days with Paul Roark's curves
> for the mis-vm ink set on an epson 1280. I have been trying to avoid
> banding, posterizing and getting the rich black with details that I
> got with the epson inks.
> 
> I do not understand how these things work, I guess, because I still
> have posterized prints and my blacks are no where near as deep as the
> epson color ink set.
> 
> I am printing on epson heavy weight matte paper and I have tried both
> the medium warm curve and the cool curve.
> 
> Straight off the net, the cool curve gave me all of the detail but
> the print was flat. At no point did I reach a true black.
> 
> I then tried the warm tone and got the same effect. No true black anywhere.
> 
> I then tried an adjustment to the rbg channel to increase the
> contrast slightly and pulled one point on the curve from an input of
> 48 to an output of 27.
> 
> The warm curve now gives me a few areas of dark dark grey, and almost
> black. It also posterized the dark greys.
> 
> Can anyone help me to get this worked out?
