Digital BW, The Print

I'm trying to make my first curve.  I'm using a 1280 with UT2 ink on
an XP machine.

I printed the ink limit page in Calibration Mode and just printed the
page again after setting the limit to 80%.  I'm trying to figure out
the  ink density percentages from gray to black.  With UT2 ink there
are four shades right?  From darkest to lightest they are Black,
Magenta, Cyan and Light Cyan right?  The relative densities of Yellow
and Light Magenta should not be figured right?  I don't have Light
Black ink.  I'm somewhat colorblind so I'm never sure if I'm seeing
color or for that matter what color it is.

Thanks for the help.

The UT2 inkset uses M and LM for the untoned carbon gray inks and C and 
LC for the cool toner inks. A curve for matte paper would typically use 
K, M and LM for the carbon curve and K, C and LC for the cool toner 
curve. Then you would blend these two to get your desired tone. Of 
course there are many other ways to do it as well, but this could be a 
good starting point.

So I should create two curves.  Warm with K, M and LM and cool with K,
C and LC to be able to combine them?

Thanks,

Tom

Yeah, with QTR I often think in terms of creating two curves that I 
intend to combine at print time with the blending function to get 
exactly the tone I want. It makes curve creation less complex and allows 
me to focus on getting a good grayscale in each curve first and then 
find a good tone afterwards.

There's nothing to stop you from creating a single curve with exactly 
the tone you want though. You could create a curve with K, M, and LM for 
the gray part of the curve and C and LC (or just C) for the toner part 
of the curve. Then you could adjust the strength of the toner by 
adjusting the ink limit for the toner ink, or by loading a custom 
photoshop curve for the toner part of the curve, or by adjusting its 
shadow/highlight/gamma parameters.

Wow, pretty powerful.  I have a lot to learn.

Thanks, Daniel, for the help.
