Determining CMYK equivalents for RGB is a complex issue. There are
formulas out there for doing conversions, but they are not all that
satisfactory in many cases. It is frequently difficult to get what you
want. It comes down to a design question basically. You could use Adobe
Illustrator to do RRB-CMYK conversion and create your own table. For
example, create an RGB swatch in Illustrator and then use Illustrator to
convert it to CMYK, assuming you like the results. Or start with the
CMYK result you want, view the graphic as an EPS in Illustrator -- or
even MS Word -- and then convert the CMYK values to RGB to make the SVG,
and finally transform with XSL. As far as viewing the final SVG images,
why not just view PDF's created through RenderX?
