RE: [colorvision_group] PrintFix Pro profile problems

2006-08-07 by Paul Nieuwenhuize

Thanks to all the replies so far and I appreciate the suggestions you all have made. Most of you have indicated that the process is normally- measure, profile and print, with little or no adjustment.
That indicates I am doing something not quite right and with David Millers help I hope to get there and produce profiles for my other papers eventually.
David,
I will get the measurements away as soon as I am able.
I am pretty sure I am not double profiling or any other issue like that, in that I print pretty good prints using the standard Epson ICC profile through Qimage and CS2 without issue. But I have been wrong on a least one occasion before (or was that I have been right on one occasion).Grin
Sorry I should have mentioned I have used the test function at the end of the profile creation phase a great deal.
Yes the print is extremely dark when a profile is created with all the sliders at neutral. I have used the test function with the back command to adjust my profile without constantly going back to my other programs. I pretty much used the test and back process until I achieved a close result and then fine tune with my known images to get closer to a result I will be pleased with.
I have colour management always set to off for this printer as I only use it for pro prints and always apply the profile within the programs I am using.
I have been trying to achieve a fully managed colour work flow to ensure I maintain consistency with any reprints or ongoing prints.
Its one of the reasons I wanted PFP from the very day Colorvision announced it.
I have to say I had no problems at all with the monitor calibration and it has definitely improved my soft proofing to my final printed image with standard profiles.
Along with passing on to you the measurements for this item, I will do a 225 patch as other people have recommended.
I will also try the multiple pieces of paper under the target.
My work bench is off white so I am not expecting to much difference there if at all, but to eliminate any other variable it will be worth it.
Thanks again for your assistance and I hope that you can find where I am going astray.
To Tom,
Yes I am impressed with the quality of the gear and work that has gone into this product. I am sure I will eventually get the results you are, and when I do, I will jump up and down and praise all those who have a hand in the making of this product.
I also see the support that Dave Miller and CD Tobie put in here and I really must congratulate them on a fantastic job.

Hi all.
As a new print fix pro user I am finding I cannot achieve the results I was expecting.
I am presuming that I am doing something wrong, but of course I need direction to see if this is correct or it is another issue

Paul,

(Having also read the other responses on the list, to your original message:
I also wanted to thank the others for answering as well: Tom, Ghi, Bill,
and Chuck)...:-)

If you'd like me to have a look at your measurements (as I did with Ed Limmy's
a week or so ago), just bundle them into a .zip file and email them to me
off list at davem@....

I can't say yet what your problem is, but no, you shouldn't expect to have
to make large tweaks with the sliders at all, and you shouldn't be getting
profiles that print the way that you're describing: dark.

The most likely reason is that something's not right in how you're using
the profile in Photoshop.

So actually, one thing you can do immediately would be this: use PFP's
test print feature (after building the profile), and let us know whether
-that- test print is also too dark (vs the tests you're printing from inside
both QImage and CS2).

That's one of the reasons why we added the test print feature to PFP: so that
it would be possible for people to evaluate the profile, setting aside the
usual procedure of hooking the profile into Photoshop.

This is important: when you do the test print from -inside PFP-, you need to
make sure that the printer driver settings (inside Page Setup in PFP) are
-the same- as they were when you first printed the target that you measured.
PFP applies the profile for you (which is what happens when that progress
bar appears, briefly, on the test print wizard screen), so you don't want
to apply the profile twice; -don't- apply the profile inside the printer
driver when you're testing this way, inside PFP.
