Digital BW, The Print

Don¹t forget to Run Quad Profile after each edit of the Ink Descriptor
files.  And close and reopen Photoshop so that the new curve is picked up.

BTW why do my posts get all these = signs when I return carriage when
responding via the website (as opposed to from my mail programme)?  IS there
something I should be doing differently?

I made one mistake in saying that the psd file was RBG.  It is CMYK but don=
't colour 
manage and your PS mode is still Adobe RGB.

I am using MIS UC inks ie colour with Eboni in the black slot.  I use "two"=
 blacks which are 
partitioned to achieve a gray scale.  For warm these are K and LK.  For Coo=
l I use QTR's 
UC_NEUTRALIZER=YES function to blend LK, LM, and LC to create a cooler LK i=
f you will 
and then partition this with K.  For HPR my Limit_K is 90 and Boost is set =
to 95 if that 
helps.

You must be able to get much greater dMax.  My understanding is that UT K i=
s Eboni or 
near enough at least in terms of dMax.  So your target should be around 1.6=
5.

Print the Ink Separation file in Calibration mode with all the ink limits s=
et to 100.  By in 
Calibration Mode I mean CALIBRATION=YES, select the .calib file in the QTR =
driver settings 
and use QUADTONE RIP CALIBRATION.  This prints the file, a line for each in=
k, at full 
throttle ie the 100 step is maximum for that ink.  You should see that the =
dMax of K is 
around 1.65ish.  But if you were to print with each ink at full throttle th=
en you would fload 
the paper so follow Roy's step 2 instructions and set the ink limit for eac=
h ink.  The 2200 
can handle quite high numbers here...80-90.  (A guide for Boost is 10 point=
s above Limit 
K.)

Having set the ink limits, print the Ink Separation file again in Calib mod=
e (this is the last
time you use the calib curve in the driver) and measure your 100 steps to s=
et the 
partioning.
