As somebody who's doing art reproduction, let me heartily echo Edumund's advice.

Here's a link to a post that describes what I'm doing; it should give you some 
idea of what you have to do before ICC profiling starts to make sense.


Not mentioned in there is that the digital part of my workflow starts with a 
DNG profile based on an automatic recognition of a ColorChecker chart but with 
a hand-drawn tone curve to produce properly linearized output (that is, 
something that's D50 Lab 50,0,0 when measured with a spectrophotometer is 
ProPhoto RGB 100,100,100 when it comes out of Adobe Camera Raw).

Indeed, I'm pretty sure that just what I get straight out of Camera Raw is 
better than any of the local giclee shops can do, but Argyll absolutely 
improves on that.
