I’ve been reading a book by Michael Kieran explaining color and other corrections via channels. I find it a little difficult to understand the writers explanations and directions, although the results appear to be outstanding, and wondered if somebody had any recommendations for other sources covering this method. He mentions that the CMYK model is better suited to this method but doesn’t say whether or not switching from RGB to CMYK and back again for printing is advisable. Any help appreciated. Regards, Murphy

Generally, once you’ve converted RGB to CMYK it is best to stay in CMYK.

There’s really no need to switch back into RGB "for printing." And here I’m assuming you’re printing on a desktop inkjet or laser.

For consumer inkjet printers, I would keep your work in RGB. From a RGB gamut to a CMYK gamut, you loose a lot of colors. Changing back won’t do any good either. When you’re printing to such a device, the data is sent in RGB to the printer and converted once again in the printer… It is hard to predict colors in that way.

Thanks JC. Yes, I do use an inkjet printer unless I have something
special,
in which case I burn to a CD and have a lab do the printing.
