Testing QTR

Testing QTR

2005-05-02 by David Sinai

Hi,

I've been doing BO for quite some time and I'm ready for a new 
challenge.

I just dowloaded QTR and I am eager to try it. But, I have two 
questions before I start:

1) When saving the file as grey scale, do I need to imbed a profile? 
Without imbedding a profile, how would QTR know/understand/interpret 
the tones in my image? 

2) I downloaded the Carl Schoefield's soft
proof file for the 2200 and QTR?  I am running a PC
and the files that I received were *.sit files, not *.exe files.

On the QTR website, the directions say: 

"See Carl Schofield's website for Soft Proofs of 2200 profiles. To 
use the soft proofs, simply install them by double-clicking 
InstallProofs. You have to restart Photoshop and then under 
View>Proof Setup you will see all the proofs."

Are these files for the Mac only?

I would like to soft proof the image in PS before I print in QTR. I 
am running a PC with PS CS and Windows XP.  Can someone point me in 
the right direction?

Thanks in advance for your help.

David

David,

Embedded profiles are ignored by QTR.  It does not "do" color 
management.  It simply looks at the raw numbers in the files and 
outputs the data.  

There are two or three popular ways to get a print that matches your 
screen.  

1.  Use Roy Harrington's Gray Lab profiles.  Edit in Gray Lab until 
you like the way the image looks.  On a PC, you then convert your 
finished file to the Gray Matte profile for printing on matte papers, 
or the Gray Photo profile for glosy, luster, semigloss papers.  This 
remaps the tonal range to fit nicely on these papers.  Use BPC and 
Perceptual intent when converting.

2.  Use Carl's soft proofing profiles.  You print a 21 step grayscale 
and create a small profile with your spectrophotometer and profiling 
software, just like you would any profile.  When you soft proof in 
Photoshop, click Preserve Color Numbers.  You will see both the tonal 
range and coloration of the profile.

3.  Some people create dot gain curves in Photoshop to visually match 
the screen display to the printed output.  Paul Roark's site has this 
procedure written out.

I believe Carl's profiles are cross platform.  He has just compressed 
the file using Stuffit.  Should work.

Thanks Lou.

What is BPC and perceptual intent?  Where do I go in PS?

When you use the Convert to Profile option, you will select either 
Gray Matte or Gray Photo at the destination profile.  In that same 
dialog box, you will see a BPC (Black Point Compensation) check box, 
and another drop down box where you can choose your rendering 
intent.  Choose Perceptual.  That ought to do it.

Re: Testing QTR

2005-05-03 by David Sinai

I have one more question:

When doing BO, I typically edit my files in RGB and just before 
printing, I convert to GS.

When using QTR, at what point do I convert to GS? Just before 
printing.  Earlier it was mentioned to edit the image in GS.

Also, if I plan to do toning with QTR, I presume I should be toning 
the image in PS as well.  Correct?  But, won't the color (toning) 
info get lost when I go to GS.  

So toning is really handled by QTR and there really is no way to see 
the image toned in PS when editing in GS. 

Sorry if it sounds like I'm babbling.
