Question about QTR Print Tool and color

Question about QTR Print Tool and color

2012-11-10 by jespes2

Hello,
I'm a happy QTR licensee on a Mac for many years, currently  using Epson 3800 and 7800.   I've never printed color until now and I am having terrible trouble. Strongly suspect it's the "double profiling" problem or whatever it's officially called, where color management gets applied twice--once by Photoshop, again by printer. The prints come out extremely dark/muddy and colors way off.

Here is my question: Is it possible to print color images to the 3800 and 7800 with the QTR Print Tool and is this a way to avoid the double-color-management problem on color images? If so, is there a recommended procedure?

Mac 10.7.5 (Lion) Photoshop CS6

Relatedly: If anyone can point me to a for-dummies guide to fixing double-color-management, I will be forever grateful. I've tried various recipes but can't get a procedure that actually works. Probably missing a  simple step; can't for life of me spot what it is. Much paper and time wasted so far,etc.

Many thanks in advance , best regards,
JP

Hi JP,

I have used the QTR print tool only a couple of times and the color images I've gotten were quite a bit lighter than my usual workflow, so I cannot really comment on the tool. That's a question for another time. I have done my color printing with the standard CS6 workflow.

I use the same basic setup as you do, a 3800 with CS6 on a Mac Pro with OSX 10.7.5 Lion.

In the CS6 print dialog at the top, Printer Setup, it is set to Epson Stylus Pro 3800. It does tell you "Remember to disable the printer's color management in the print settings dialog box." I show this in my second screen shot.



In the print settings I set it as seen below. Color handling is set to "Photoshop manages colors." I then set the profile for the paper I'm using.



When I do this, I get nice color prints. 

Let me know if this is helpful or if you need something more.

Best,

Eric

JP,

As Eric said, you can use the print tool to print color prints and utilize paper profiles to match colors much more closely.

The reason he mentioned that his prints coming from the print tool are much lighter is because the print tool is completely circumventing an issue that apple and adobe have created with color management - when printing with photoshop on OSX 10.6.x or newer, your images are still being color managed twice, so the printer is being told to lay down more ink than is necessary.

I've done extensive testing in our lab comparing the print tool to printer color management, photoshop color management, and colorburst rip with both color and black and white output and using QTR Curves in the print tool.  

The print tool and colorburst rip are instructing the printer on how much ink to lay down correctly because they are overriding Apple's ColorSync correctly, photoshop does not do this anymore.

Roy will be able to speak more knowledgeably on how this works (it's still too early in the morning after shooting a wedding for me). 

After all the testing was done, I don't even use Photoshop to print anymore - I output all color and black and white prints through the print tool, and this is a workflow that is being added to our advanced printing class.

Re: [QuadtoneRIP] Question about QTR Print Tool and color

2012-11-11 by Jim Stewart

Nick, can you provide a quick primer for those of us who got as far as JP and said after printing color with the Print Tool ".. well, that didn't work?"

If we use the QTR Print Tool for color, must we re-profile all our papers using that particular workflow? Or is it a matter of setting a button or two in the Print Tool config screen? I use ColorMunki to profile my papers, and it bypasses any Adobe/Apple/Photoshop configurations when generating the profile (I assume). Still, when I print from either PS or Lightroom, the prints look right on so long as I use the Colormunki-generated profile. When I tried Print Tool using the same profile, colors were way off.

Thanks,

Eric and Nick,
Thank you  very much for your replies. Bought the Print Tool this a.m. and will do some experimenting.  Please count me with JRS--any tips for Print Tool color noobs welcome over here too.
Thanks again and best, JP

Re: Question about QTR Print Tool and color

2012-11-11 by Eric Brody

If I'm understanding Nick correctly, my "too light" color prints with the QTR tool will require me to re-profile my monitor with my X-Rite Eye-One Display 2 device. It would seem that to match the prints from the QTR tool, I'll need to brighten my monitor significantly  to get it to match the prints from the QTR tool?

I'd love to know how the PS printing "double profiles" the process. I also wonder, as did Jim Stewart, whether I'll need all new color profiles. For my limited color printing, I've always used the canned profiles from the paper manufacturers, and have been pleased with the results. For black and white, of course, I use the QTR profiles. 

Nick was kind enough to make a QTR neutral profile for me for Canson Platine Fiber Rag, a lovely paper albeit expensive. Embarrassingly I did not realize, I'll need warm and sepia ones as well to use multiple curves. Sorry Nick, I've been meaning to send you a heartfelt thanks you note as well as asking if you'll make a couple of more curves.

Printing is an amazing world.

Re: [QuadtoneRIP] Re: Question about QTR Print Tool and color

2012-11-16 by Roy Harrington

Color Management sure has gotten to be a mysterious thing.
Conceptually its not that complicated
but in practice its hard to know who's doing what.  In general there
are 3 main players -- the application
(photoshop, lightroom, qtr-print-tool, or something else), the
operating system OSX (colorsync is apple's
CMS) and finally the driver (Epson driver or QTR driver for B&W).
Unfortunately they all want to get into
the act -- but you need just exactly one to do the actual CM conversion.

The concept is to print out a target with no color management
happening, measure it and create a profile.
Then from then on print just introducing this profile into the print
workflow.  The important thing though is
that all the settings while printing have to be IDENTICAL to those
that were used when printing the original target.
The problems arise -- if you use different print settings, if you
print with different apps maybe they do
different things, if you print with a different OS maybe something's
different, if you have a different driver
version they may have changed something.  Not that all these things
are likely a problem but sometimes
they are.

In practice usually it depends on where you got the profile.  Epson
profiles for Epson papers for a specific
driver tend to work pretty well.  Downloaded profiles from
someone/paper manufacturer are harder to
know how they were made.  My case for a custom paper showed one
printer's profiles too light and one
too dark. Making my own fixed with Print-Tool made both printers work
just fine.  The important thing
is to always use OSX Print Presets to make sure you have consistent
settings.  CS6 is particularly tricky
here because there are settings in the Preset and settings stored with
the image.  Make them all the same.
Most of the settings show up on the Print Settings print dialog pane
but the Color Matching pane can
also be important.  CS6 Manages Color will force Color Matching to
ColorSync so if you want Print-Tool the same you
should check this and make it ColorSync as well.  If you have a
working setup its hard to give a guaranteed
answer -- try various ways to see what works.

QTR question - Mac error.

2012-11-16 by Kerik Kouklis

Hi Roy,

I use QTR for making digital negatives. I got this yesterday when running the install.command after modifying an ink descriptor:

Creating curve Pd_KK_3800-UOHP_aa_pc_1
Couldn't open /Library/Printers/QTR/quadtone/Quad3800/Pd_KK_3800-UOHP_aa_pc_1.quad for writing: Permission denied

What did I do wrong? Or can I blame Apple? I've attached the ink descriptor that failed. 

Thank you!

Hi Kerik,

The error indicates that the file is read-only to the program trying
to update it.
Possibly you're running as a different user id or the file's
permission was changed.

So the fixes should be pretty easy.  Either run as an admin user that
can overwrite the
file or just go to the folded
"/Library/Printers/QTR/quadtone/Quad3800/" using Finder.
Just drag the .quad file to the Trash.  (it may ask you for a admin password).

I'm pretty sure you will be fine then.

Re: [QuadtoneRIP] QTR question - Mac error.

2012-11-17 by Kerik Kouklis

I was actually trying to write a new file to the library, not do an over-write. It turns out that the Printers Library was set to read only. After changing the permissions on that folder, the error went away and the Install worked. What's weird is this seemed to occurs spontaneously. This happened during a workshop and I had demonstrated editing and installing new ink desciptors successfully, then it just stopped working. I hadn't logged out or changed users or anything.   

For those who don't know (and as I just learned), to change permissions on the printers library, you right click on the folder and click on Get Info. The permissions controls are at the bottom of the window and are fairly self-explanatory.

Why do these oddball errors occur during workshops when I'm supposed to know what I'm doing? :-)

Thanks again,

Re: Question about QTR Print Tool and color

2012-11-26 by nmenghardt

Eric, JP, and J Riley,

Sorry this has been a long time coming - final projects and exams are almost due for the students in our programs so assisting with printing and technical issues has taken most of my time, however I've been able to put together a quick "How To" with the print-tool.  The link so to our internal wiki that we've set up for the students.  The wiki is basically a digital version of our instruction manual we give to students for all the various applications and hardware that they use including instructions on printing and profiling papers.

Feel free to browse the different sections but keep in mind some are still outdated as we're constantly updating software (specifically the QTR section on building curves still shows how to use profile maker 5 rather than colorport).

http://digi.stedwards.edu/wiki/index.php/QTR-Print-Tool

The wiki article on the print tool covers several different workflows from basic work prints to final prints using paper profiles and using QuadTone RIP for grayscale output.

As far as re-profiling monitors, you shouldn't have to if you're using the correct settings - 120 cd/m2 for LCD monitors.  This change in luminance might be an adjustment for some photographers, but you should start to see closer output values in your shadows.  Using a too-bright monitor can result in dull and even nearly gray blacks.

If you'd like to shoot me direct questions, my email is nicholae at stedwards dot edu

Cheers and I hope everyone had a great Thanksgiving.

Thanks for posting this, Nick.  It is really useful for someone starting out with the printing tool.  I wonder if there is a way to put a cop in the files section here.

Re: Question about QTR Print Tool and color

2012-11-27 by nmenghardt

John,

Good idea!  I've put it in the docs/qtr-print-tool folder.  You should have gotten a message about it.  It's just a PDF created from the wiki article I posted.

I will be doing an article on creating curves using the print-tool and Scott Martin's ColorPort workflow with an i1pro.

Re: Question about QTR Print Tool and color

2012-11-27 by john

Thanks again for doing this.  It should be a great resource for new users.  The print tool is such a useful program.  I am so grateful to Roy for creating it.
I am looking forward to reading your article on curve creation as well (although I use a densitometer and enter values manually.)  The more documentation available the better.

Re: Question about QTR Print Tool and color

2013-08-02 by James Stewart

Well, it's been months since I got back to this problem of printing color accurately from within QTR Print Tool. I made two prints in PT, both of which had colors way off. I normally print from Lightroom, and when I printed both prints again from that app, the colors were spot on.

So looking at the print dialogue boxes in PT, I think I see where one could accidentally tell it to profile the print twice (no, you wouldn't want to do this, but the PT app doesn't prevent you from doing it). 
1. By checking "Application Managed" in the Print Color Management box, indicating the paper profile you need to use, and then
2. Checking "ColorSync" and then naming a paper profile in the "Color Matching" section of the "Print..." dialogue box in the Epson driver.

Correct me if I'm wrong, but I think you need to do ONE or the OTHER, never BOTH. If you name the profile from the Epson driver "Print..." dialog, then set "Print Color Management " in Print Tool to "NO COLOR Management"

Which, BTW, is recommended?
