Soft Proofing With Photoshop

I have frequently utilized Photoshop's soft-proofing when making prints.  While I have found it useful for getting a general idea of how the print might look, I have also found that the prints would come out with more contrast and with colors appearing far less out of gamut than soft-proofing might suggest. This despite having a monitor that is fully calibrated. Just recently, I saw an article that extolls the process of making hard copy 'soft-proofs' and thought it might be interesting to folks who read this blog.  It is called "The Hard Truth About Soft Proofs" and was written by West Coast Imaging.
