Using Krita for RGB to CMYK conversion.

[John Culleton]

If I import an rgb model jpg file to Krita, change the color model to cmyk, 
then export the file to another name is this an efficient way to convert from 
rgb to cmyk?

After the conversion, does  the on-screen image in Krita have a gamut similar 
to the real gamut of the CMYK image?

The "best" format for my publishing program is pdf. Krita doesn't offer that. 
Among the remaining choices which is the least lossy for printing, jpeg or 
png? I can't use tiff in my publishing program (pdftex.)
