Film is a whole nother business. You've got a lot less control over
its 'colour settings' than you have with a display screen, and ditto
re optical linearity. The issues with an LCD screen are quite
different.

well in the sense that they all use combinations of RGB (or CYMK) to
produce a 'full colour spectrum'and none succeed perfectly for all
applications, they are considerably identical, actually.

No, they aren't.

Very basically, you have to understand that:

A printed image is sending reflected light to your eye. It can only
reflect
some portion of the spectrum of light it has absorbed.

A screen is is sending transmitted light to your eye, which has no
reflective element to speak of.

Put even more simply, a printed image varies dramatically under
different
lighting conditions, unlike a screen.

They could hardly be less identical and the analogy with different
brands of
film is not applicable at all.

issues very different.
Proof by assertion.

Go read some textbooks on the subject of colour management for screen &
print. The topic is far too complex to sum up from first principles in a
newsgroup post.
