Is there a way to do batch process of converting .jpg or .tif images from RGB to CMYK?

Yes.

1) Write our own GIMP script that will make use of separate+ and run it from console.
2) Use imageMagick's convert console utility. 3) Use CMYKTool and forget about console.

If you go for CMYKTool, I compiled it (CMYKTool-016pre1) in linux but when it comes to windows and Gimp 2.8.x then there are some adjustments to make.

The bat launcher is set up for gimp-2.0/-2.2/-2.4 and will need to be updated to something like PATH=%PROGRAMFILES%\gimp 2\bin;%PROGRAMFILES%\inkscape

A couple of file changes. Does not seem to find libcairo-2.dll so *copy* this from the ...\gimp 2\bin folder to the CMYK\bin folder Requires libtiff3.dll which is now libtiff-3.dll so *copy* this from ...\gimp 2\bin to CMYK\bin and rename it.

All being well it should work.
