Exactly - but the colour "white" in your CMYK eps *is* the "colour of
the paper". This is why there are different colour profiles for
different kinds of stock. It's why when you create 4 colour CD labels,
you need an extra whitewash channel, otherwise all your colours will be
up the creek.
So you must take into account the colour of the paper in your
conversions to and from RGB.
The particular blend of CMYK inks to get a particular shade depends on
heaps of things - the colour of the paper, how much the ink spreads, the
screen frequency, etc.
This of course means that its really hard to get a good proof on screen
of what you will get on the press :(
