That is because it is a rather complicated matter, if you think its just >convert to CMYK<,...... its not! First off, converting from RGB, you have to be very specific about which RGB color space! There are Adobe RGB(1998),ProPhotoRGB, color match RGB, sRGB, BruceRGB, JoeRGB,AppleRGB. monitor RGB spaces, digital camera RGB spaces, scanner color spaces, and RGB printer/paper color spaces, etc. Now, all these RGB color spaces are all different from one another in color gamut, white point and/or gamma! If you supply the wrong RGB color space, you will get very different results in color and tone. All that is the same with CMYK, there is no one CMYK color space. All that requires you to be very, very specific about all aspects (including,"where in the world is the file going, what type of printing press, ink, paper will be used, standard process or proofing system profile and specific press profile, what type of black generation and what ink limits are needed. All that and much more will be needed for a correct conversion. Back in the days they had special craftspeople (scanner operators) just for this task to be completed, so it is rather involved, just a click on >convert to CMYK< will obviously not be satisfacatory! One of the problems with converting from any RGB space, to any CMYK space, is that you will be reducing the gamut of your image to something much smaller, hence the lack of saturation (even to the point of lack of color at all in your case, which demonstrates a wrong CMYK profile

As far as I know there is only 1 CMYK color space. Its called CMYK.
Iv'e worked in the Pre-Press dept for over 20 years. A lot of what you say is technically true but its not nearly as complicated as what you make it out to be, especially since he was talking about a news paper which is probably printing at around max of 200 dpi.
