[Frameworks] color separation

[Daniela Zahlner]

hello,
does anyone know how to exactly make a color separation?
i want to have a similar effect as in this film:

http://www.lightcone.org/en/film-4886-3part-harmony-composition-in-rgb-1.html


as far as i understood you shoot b/w film three times, each time with another filter (or two?).
i found these numbers:
Wratten color separation filters
Filter no. 47 blue 
58 green 
25A red

and then just print to color print stock?
and what if i shoot reversal?


does anyone have experience? any lead would be helpful!
