Can a profile be created for other than original size, i.e, 4x6? I am using a paper that I don't have in 5x7 or larger.

Hi Don
As no one has answered you I'll have a go. I created a profile as normal from the A4 size of the same make/paper type as the 6x4 and chose that when using 6x4 size.  It seems to work OK.

John, thanks for responding and your experience is encouraging. I will give it a try.

Seems the others are too busy with QI so thanks again.

Don,
It has been my experience over the years that the target print *must* be the original size for the scan to fit the matrix that Profile Prism is expecting.
If you go to any decent office supply store, or Atlex on line, you should be able to get a small pack of 10 sheets of 8.5 x 11 size.
By the way, even 5 x 7 is too small.
The target size is 7.92 x 5.77 inches,
So you would need some 8 x 10 or larger.

Good luck
Fred

I don't think this is true.  PP takes it's cues from the placement of the corners when defining the target area, so the size of the print or scan doesn't really matter.  I've made 4x6 prints, scanned them at 600 dpi, loaded them into PP and they worked just fine as far as PP was concerned.  By tweaking the corner placement, I was able to get all of the punchouts to align with their respective patches.  The only drawback with this method is that the area sampled from the original print is much smaller than with a larger print, so any variability in the resolution of how the printer lays down ink will be magnified when using a smaller size target image.

Thanks! Interesting conflict of ideas.

Don

Don,
It's not a question of "ideas", it is what PP instructions say: print the target at original (embedded size) as Fred has said.
Surely it's not a big deal to get some 8.5 x 11 (or A4) paper of the same type as the 6x4 paper you have and do the job properly.
Terry.

Thank you Terry.
I was out!
I had to help a neighbor with an electrical problem, but I was going to point that out as well as mention that I didn't say it wouldn't work, I just pointed out that Profile Prism is designed to work properly with a proper target size.
To illustrate!  Let me draw this analogy.
Your auto manufacturer recommends that you carry 30 lbs per sq in of air in cold tires for proper performance of your tires.
You decide to run your tires at 15 lbs. per sq. inch, for whatever reason such as you don't feel like bothering to pump the tires to the proper pressure.
Sure, you can make the trip. You will get there, and get home again.
Is that why you paid good money for the tires?

Fred

Fred, Terry, let me explain the "big deal". I have several boxes of Inkpress Duo Matte 80 4x6 which I would like to use. This paper is not available at office supply stores or Atlex. What I have found online is relatively expensive in the sizes available, like $51+ for a box of 50 shts.  :o

Just a thought, how many automobile tires are run with recommended pressures, certainly not close to 100%.  :-\

I'll just forget I posted here.

Don

Don,
Now we know the background to the problem ....
What about:
1. Inkpress have profiles available to download, have they got one for your printer?
2. If you print with Qimage, try using the "let driver manage colour" setting; you need to set the driver to ICM-Applied by Printer Software (Epson terminology)

Both of these options are likely to be  better than a dubious profile made from an under-size target

I hope not, and if they are, keep well away from me on the road  :o
Terry

Sorry, Don,
Didn't mean to ruffle your feathers, but it might have helped us to form a better picture of your needs had you explained the situation.
On the other side of the coin, you do realize that *we*, all who post here, are trying to help you.
You seem to take the position that any reply that is not what you wanted to hear is hurtful in some way.
I speak for myself, and for Terry, John, and countless more folks on here that try to help others, that we meant you no harm.
Have a happy day!
Fred

Cheers!
