This may sound like a rather stupid question, but…if one is working on something which is mostly meant to be printed, is it better to just start in CMYK, or work in RGB and then convert to CMYK to print?

it depends…

If you need the file to go to multiple devices, RGB would be a better choice because of the generation of black to CMYK.

If you need to retain black only elements such as shadows or vector text, use RGB with color fill layers & masks or editable text layers. That way, you can change the color designation of said elements after the conversion because it will now be 4 color based upon the CMYK profile or color table that has been used for the RGB to CMYK conversion.

IF you are doing crazy things like ad agency, job justifying edits, like taking a 1% magenta out of a models lips for color matching an actual product, I’m afraid you’ll have to work in CMYK because doing so in RGB is NOT AN OPTION, at this time.

Just make sure you use a well defined/created profile that describes your device.

OR

Separate the file for SWOP coated sheetfed or web, if device is unknown.

If device is known. convert to that devices color space and blast away after retouching and color adjustments are made….

IF, device is not known, than known after the fact, convert from CMYK to RGB, but assign the correct source color space before converting to RGB ( ADOBE RGB) and then to CMYK, known color space.

Mix well until acquired insanity fills your thoughts……… and you just say F&%* it and move on.
