Never. Leave them as RGB.
All modern printers should happily accept RGB images. PDF/X-4 is the modern
standard. X-1a can only be described as archaic.
Thanks Bob! If modern printers accept RGB yet still print in CMYK, would I not still expect a color shift? Is there any way to preview that shift? Certain RGB colors can really lose their luster when converted to CMYK.
It's quite likely there will still be a color shift, but unless you already are converting to the correct CMYK space for the printing condition, you will always get better color letting the printer do the conversion at the RIP.

To see in InDesign what color shifts will occur, use View=>Proof Colors.
I would also recommend View=>Overprint Preview.
Yes there are color shifts when converting RGB to CMYK, but those are due to the fact that the gamut of CMYK is significantly less than AdobeRGB or even sRGB. The same color shifts going to CMYK will occur whether you convert the image in Photoshop or in InDesign during PDF export or at the RIP.
Keeping the color in ICC color managed RGB has the advantage that last minute changes can be made as to what CMYK printing conditions are used, i.e. all CMYK is not the same. Furthermore, if you convert RGB to CMYK early in the workflow, you lose the ability to maintain the color gamut for display of the PDF as well as for printing to high fidelity color devices, i.e., offset or digital (especially inkjet) devices that have extra colorants such as light cyan, light magenta, orange, and/or green to dramatically expand the gamut. Once you lose the gamut in your imagery via conversion to CMYK, you can't go back.
Thanks All... From this point forward I'll leave my images as RGB and let the printer do the CMYK conversions.
Just tested, and had no difficulty embedding Fontbit Rokoko into an
ePub. It displayed fine in Readium. Adobe Digital Editions does not
support RTL, so the text was back to front, but there also the font
itself was fine.
I haven't tested in iBooks.
So it seems to me that InDesign has no problem embedding Hebrew fonts in
ePubs -- the problem is more likely to be on the part of the ePub
reader, which is not displaying them properly.
Just to add to Dov's point about CMYK, the colour gamut is significantly smaller than RGB, so if you're printing, for example, 4 colour litho, don't expect bright greens and oranges.
Ariel, somehow your reply ended up on this thread. I think you meant to respond to a inquiry on the EPUB forum under "Which Hebrew fonts are supported in epub?". You might want to re-post it there.
Ellis, thanks, yes you're quite right!
