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:
http://www.usq.edu.au/users/grantd/WORK/216color/ConvertRGB-CMYK-Grey.htmThere'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.
