Nick,
I am not exactly sure what you have done, but let me ask a few questions.
Do you have two profiles, one for your rgb ink jet printer and one from a
printing press that you want to simulate on your ink jet printer?
How do you know that your printer is capable of printing the same gamut of
the press?
Where did the press profile come from?
Does the paper color of your ink jet paper match the paper you are going to
print on?
Is the press profiles white point the color you want printed on the paper
of your inkjet paper?
Do you have a known color image that was color separated using the press
profile with reference colors and memory colors that created a pre-press
proof from the service provider that they claim will matches their press?
You can do simulations but there are few things you might need to know.
I think you might want to try something like this.
You have an RGB image open that is in your monitor working space. You go to
the Photoshop View Menu/Proof Setup and choose a printer profile.
Then you go to print in Photoshop and come to the dialog box where you have
the option to use the source space from your RGB WS or to choose your Press
profile as the source space.
Then you can select your RGB printer profile in the print space or
destination dialog option. At that point you have to make some choices.
Which rendering intent do you want to use? Perceptual, Relative
Colorimeteric or Absolute Colorimeteric
If you choose Absolute Colorimeteric then you will get white point of the
press profile printed on your ink jet print.
If you don9t want the white point of the press profile printed on your ink
jet print they you can choose either Perceptual or Relative Colorimeteric
based on the images content. If the image is dark looking and has a lot of
out-of-gamut colors you might try Perceptual.
If you choose not to have the white point of the press profile printed on
the paper then does the ink paper match the paper you are going to print on?
If the white of your ink jet paper does not match the paper color of the job
you are going to print, then there is another factor that might mean you
wont have a visual match from your ink jet printer to the press sheet.
My rational for having a known image with reference colors and memory colors
that made a pre-press proof is to save the head scratching exercise you have
embarked on. Working with know targets, images and pre-press proofs gives
an indication if your ink jet proofing system is or is not working
correctly while you are setting up this process.
Is what I have described the type of information you are after?
