Digital BW, The Print

I downloaded QuadToneRIP yesterday and have been making wonderfully
detailed prints with it. 

For those of you who have not used it, it is a heck of a program!  It
is easy to use and will significantly improve your print quality.

However I immediately hit a significant road block and have not
figured a way out yet.  I am using the UT inkset with Epson 1160 in
Windows XP Home Edition but no matter what I select for curves, all my
prints are coming out with warm tone.

Here are my settings: 

1160 printer driver
Printing model: Quad1160
Media Type: Matte Paper
Resolution: 1440 Super, Speed: Better
Dither: Ordered
Curves UT-EEnhMatte-cool, UT-EEnhMatte-cool, Blend: 50%
Ink Limit Adjustment: -10
Gamma Adjustment: -10
(The latter 2 settings are because my image is on the dark side and I
want a lighter print.)

Course I have checked the nozzles and they are printing perfectly.

Any ideas?

Much appreciated,

Edwin, I don't know your printer or the UT inkset. Since you're using
QTRgui you should just be thinking about sliders, not curves. Your
printer Settings should be neutral or close to it.

JK,

You are correct.  I am using the slider in QTRgui... and it doesn't
matter which way I pull the slider or how far or what items I have
selected for the combo boxes at each end of the slider.  I still end
up with the same warm tone on my print.  Granted the print is
beautiful, but I can't control the tone.

FYI, the MIS UT inkset provides four colors -- one cyan, two shades of
warm grey and one black.  This allows you to create tones ranging from
cool to warm.  

I started out by using Paul Roark's curves in Photoshop but after a
couple of months of trial and error, I still can't control the dot
gain so I thought I give QTR a try.  

Best regards,

Edwin

The slider won't help you because it specifies the blending percentage 
when you specify two different curves, and you've specified only one 
curve (albeit twice).  You might as well specify "none" for the 
right-side curve and a blend of 100%.

Typically, when blending, one might use a warm curve and a cool curve 
together, and blend in enough cool to get neutral.  However, if you're 
using only a cool curve and already getting something too warm I'm not 
sure what to recommend.

Walt,

Please note that the curves I had selected were both cool but I am
still getting a warm print.  The problem is that no matter how I
combine the UT curves -- what UT curve I select and where I put the
slider, I still get a warm tone.

I must add though, that when I selected none for both curves, I ended
up with a neutral image but I got those thin banding patterns.

Best regards,

Edwin

I had this problem with an earlier version of QTR2, and the reason was
that the curves are named for the sepia set, where the black and greys
were 'cool' and the toner gave a warming effect. So 'cool' meant no
toner, as you are seeing. There wasn't a curve to give a strong cool
effect. I haven't got round to looking at the current version, as the
version I had gave repeatable problems with fine black lines (which I
use as keylines) making it unusable. Nothing in the release notes gave
any indication that an attempt had been made to address this issue,
and I've been busy with other things. I've reverted to using the Roark
curves until I have time to spare (or money for a 4000; even less
likely!)
