That should be useful, at least as a start.  Typically the driver will tweak
things a bit to deal with various things like media settings and the
specific inks used.  

 

Using the calculator as a start and then perhaps iterating by printing the
calculated color and adjusting as needed to remove any stray undesired
colors should work.

Here's a calculator:

There's no guarantee that using solid colours in RGB (eg Cyan is Red=0,
Green=255 & Blue=255) will give you pure CMYK colours when printed though.

Easy enough to find out I suppose.
