It was just my understanding that RGB is for web/intenet only and was not to be used for printing as it has to do w/light, not ink.
Adobe apps let you make color conversions anywhere in the workflow. So there isn't a problem with editing images and color in an RGB color space and letting the conversion to CMYK happen at output.
For multipurpose cross publishing it is the best to use RGB images and place them in InDesign. So you can export them to RGB or CMYK output with high flexibility.
If I want to print my ID creations at home then I should use RGB?
Yes - Just had the same issue myself. You can use sRGB through the entire workflow.
If I print from a local printer or allow my client to print using their local printer, I should provide a .pdf output in CMYK?
I wouldn't convert anything to CMYK if it's printed out locally.
What is the best type of printer to use for home printing in RGB (inkjet or laser)?
Depends how much money you want to spend. Inkjets are cheap and do a good job of accepting RGB data.
When I present my work online for others to see, should I be presenting it in RGB or does that matter? I dont want show it
in vivid color, only for the client to have my work printed and it looks nothing like the online presentation.
