Chick,
Soft proofing doesn't really work well with RGB profiles, is it more
effective with CMYK press profiles because those presses lose a lot more
color range compared to what the monitor shows. When preparing files for an
RGB printer like a Fuji Frontier or other digital minilab, or for an inkjet
printer (injets are designed for RGB input despite using cmyk inks).
Here's what you do: Make the image look the way you want in sRGB, then
convert to the printer profile you have using the 'convert to profile'
command. You'l probably want to do this using Perceptual rendering. Many RGB
output profiles give bad results using Relative Colorimetric. An easy test
is to take a file and convert it both ways and send both files to the lab
and see which looks closer to your screen. But I am betting on Perceptual.
Save the converted file under a new name so you don't lose the original sRGB
version. When you save, DO NOT embed the profile....Fuji Frontiers don't
like to see an embedded profile. Then, send the converted file to the
printer. Your print should be pretty close if your screen is calibrated
right.
