Excellent post.

I would like to disagree somewhat here and add a feature suggestion.

The one publishing application which got colour right was Cerilica's Truism --- it used individual ink definitions instead of multiple ones, and instead, had a concept of ``substrate'' w/ attendant colour and ink absorption characteristics at the page level.

This allowed one to define a spread has having two _different_ types of paper (which often happens when one has a cross-over ad at the inside front (or back) and first (or last) pages of a magazine) and to have the ad previewed on-screen as it would actually print.

One could also do coloured paper and preview how the ink would appear on it, or separations w/ arbitrary ink (an amazing example I saw once was a jeans catalog printed in blue and brown which looked amazingly lifelike despite being printed w/ only 2 inks --- this inspired me to do a bell pepper vegetable display box once using red and green inks which we mixed to create brown so as to make a quite nice print of a full-colour photograph despite using only 2 inks).
