How to "hard proof" in Photoshop?

[Dario]

Hello everyone,
I would like to understand - using Adobe Photoshop - how to be able to change the pixels of an image so that they look as if a soft proof was applied.
(I attach an example)
The image above (1) has profile Fogra39, and does not have soft proof active;
the image below (2) is the same as above, but with soft proof active using a particular icc profile;
the pixels of the two images are the same, only the appearance on the monitor changes.

I would like to have an image (3) that, even if saved/printed with the fogra39 profile, looks like (2), so it's a different image from (1) - the white point must change too!

The reason?
I need to be able to reproduce on coated paper a photo that was printed by someone else on very bad brownish uncoated paper (I have that icc profile).

You may want to use "Turning on View > Proof Colors". Note that you need to set the format of the proof first (View > Proof Setup).
Obviously, this will produce the best results with a calibrated screen.

But that only affects the appearance on screen ...right?

Profiles be damned - you are asking for trouble.
You should change the photo to match the observed/printed sample.
Your examples show what should happen if nothing changes between the screen and press - and nothing will change.
Now all that said you COULD make this happen with profiles through trial and error (don't ask) but it's inexact and non-replicable.
YMMV.
