In Photoshop 5 your image was sent through the return table (that you just
tweaked) to the RGB workingspace, and from there to the monitor profile, if
"display using monitor compenation" was checked. In Photoshop 6 it is sent
through the same tweaked table directly to the monitor profile (bypassing the
RGB workingspace), and does not offer non-compensated display. Both use the
same rendering intent's table for viewing, so that should not be a variable.
LinoColor allows you to convert through one intent, and view the softproof
thorough a different intent's return table. PS5 does not allow this at all.
PS6 allows an absolute return on a relative colorimetric or perceptual conver
sion by checking the "paper white" and "ink black" checkboxes in the proofing
set-up. Your profile needs to have the necessary tables, and appropriate
white point data, in order for this to be effective.
