You can test this easily enough by putting the same image on screen in both RGB and CMYK. Properly set up you should see no visual colour difference to affect most retouching applications. Of course when replacing colours to print to a pre-determined colour, such as matching the colour of a product it would help to use CMYK and read the numbers.
Properly set up there is no problem with viewing CMYK. I have seen very good operators doing CMYK colour corrections in Barco monitors for high quality repro.
The reasons to retouch in RGB for me are different.
1/ The RGB is a smaller file than CMYK if the size of the repro is the same. It is faster to work on a smaller file.
2/ If the file is likely to be re-purposed for more than one use then you only have to retouch once.
3/ On many occasions the file will be scaled down in size when converting from the RGB original which means that some retouching will be disguised by the interpolation.
If you don't already get the free magazine Print Media Management you should. Articles from back issues are on their web site at.....

This is a recent one about pushing the RGB workflow further down the line to the printer.

'A monitor cannot display CMYK data correctly so it is impossible to retouch

and this from someone on a Barco monitor.
Anyone know what he meant?
