Hi Mike,
I assume that you're talking only about ony imitating the uncoated substrate color and not its lower contrast and saturation. Of course you can do this by editng the white point of the destination color space. But perhaps the goal is unclear to me. Normally one would expect the show-thorough of a warmer (and or darker) stock to influence lighter colors and accept it as a given. The eye takes its cue from the paper white (assuming some paper is visible), so all colors are seen in relation to it. If, on the other hand, the customer is asking for the colors to match in absolute rather than paper-relative terms you have a problem that can't be simply edited away--certainly not for very light colors. Any such attempt would risk some nasty tonal breaks in highlight areas, as the correction would be of increasing severity as coverage decreases to zero. In an inket proofer we would just apply absolute rendering to lay down a correcting tint to the paper white as well, and this is usually accepted, but anything like this on a press sheet would just be seen as scum dot.
