Digital BW, The Print

Hi ---- I was wondering if anyone out there has ever made ICC profiles
for UT-14 inks that give a range of tones on Glossy Paper between the
Pure Golden Sepia and the Neutral B&W that Paul so kindly provides on
his website?

I personally find the 100% Sepia too Golden for most of my uses, and
would love to be able to create warm tones closer to that of UT-RC Warm
inks ... which I find are more moderate. Yet I like the GLOP feature of
UT-14 and would like to stay with this inkset if possible.

Unfortunately I am not very adept at creating my own ICC profiles, or
else I'd have made a range of them in-between Sepia and Neutral and
posted them for everyone else. So ... if you have created any additional
ICC profiles for UT-14 on Glossy Paper that lay in-between Pure Sepia
and Neutral B&W and wouldn't mind sharing them with me, I am at
markss9876s@... <mailto:markss9876s@...>  . (note the extra 's'
after 9876).  Please use this aol e-mail address, as I use my Yahoo
e-mail for other things and your response could get buried for a while. 
[:)]

Thanks for any help. Mark.

Try putting the neutral and warm curves on layers over an RGB version of the 21-step test curve, and then putting the opacity at 50%.  See if it is close enough to linearize.  If so, you can make an ICC with that same mix on the QTR rgb-raw-16.psd.

Hi Paul --- I'm grateful for your response, but --- gulp ---- I'm too much of a nerd to fully understand it.

I assume that I load the identical step test curve into each of 2 individual layers, one layer with the warm ICC profile and the other with the Neutral.

Then I set the opacity setting of each layer to 50% --- ok so far.

Am I correct that by "See if it is close enough to linearize", you mean that I should judge if I like the look of the resultant Sepia tone(?) If so ....

Now I'm lost --- sorry for being such a newbie. Could I trouble you for just a few more details of "click on this" then "click on that" in QTR? I don't know how to use it.

Thanks Paul. I am sure you spend a lot of time answering questions and I am sorry to impose.  Mark.

PS - If anyone else smarter than me tries this and gets a favorable result before I figure it out, please post it or send to markss9876s@aol.com.  Thanks.

I don't have a variable tone inkset set up now.  So I can't test this.    I'm wondering if applying 2 curves, one each to 2 test strips, and then putting one of the test strips as a layer at 50% on the other might work better.  At any rate, you probably see what I'm trying to do -- get a blending of the curves.

Tone is one issue, but the other that I had in mind was to be sure the 21-steps were still separated -- no totally flat spots or posterization.

The ICCs I made were made with QTR's Create ICC-RGB.  See 
http://www.paulroark.com/BW-Info/Embedding_Photoshop_Curves_in_ICCs.pdf

You basically drag both the linearization data and the curve into the Create ICC-RGB icon on the desktop.  The curves are entered via a little image file: rgb-raw-16.psd.  You should be able to combine the curves on this file just like you'll try to do on the 21-step test file, a print of which is where you get the linearization data.

Hope this helps.
