When you take an RGB screen capture that includes the color gray (for example, most dialog boxes on MS products), that gray is created from equal percentages of red, green, and blue. When it is automatically remapped to CMYK, most programs simply replicate the relative percentages in four colors instead of three. When you go to offset printing, this can result in a massive moire effect in which you have a shimmering composite gray when what you should really have is a tint of just black, without the other colors.
