  I always ask if there's a specific CMYK paper profile that they're using. If it's one that's in Photoshop, I'll target the conversion to that. Some printers /designers also have a CMYK profile that they can send you if they know exactly what paper they're printing on and on what kind of press. Also- some people make the mistake of trying to convert the image to CMYK by going to "Image>Mode>CMYK Color" and that doesn't really do much except for guarantee bad color match. If you're converting in Photoshop you should be doing it "Edit>Convert to Profile" and then select your target CMYK profile.

  But don't expect CMYK printing to match the clean, saturated color you've got on your monitor or you get off of your photo inkjet printer unless the printer is expecting to use bump plates (extra ink or dyes) for specific colors to increase the saturation. C,M,Y and K contaminate one another and really clean, vibrant color isn't usually possible on most common printing presses without additional pure inks being laid down. (That's why photo inkjet printers now usually have at least 6 inks)
