Paul asks: I am trying to convert black & white line art bitmapped images into a rich black (100%K 60%C 30%M 30%Y) and white. When I convert from bitmapped to grayscale to CMYK, Photoshop automatically changes the blacks to 75%C 68%M 67%Y 90%K. Is there a way to get it to automatically convert it to the rich black percentages that I need?

Answer: The CMYK mix you get when converting to CMYK mode is completely dependent on the settings used in the Color Settings dialog box (Photoshop menu on an Mac or Edit menu in Win). Clicking on the CMYK Working Space pop-up menu in that dialog box and choosing Custom CMYK will allow you to modify the settings. You might also try choosing Image>Adjustments>Channel Mixer and dial in the amounts you need to each channel.
