    Just dont forget to set it back to default medium black afterwards!
    I used to have macro for this and 100% black only.

    Also try playing with different options for black so you see how it works, it might come in useful for a project in the future :) But yeah, follow what gsbj said, good luck!

    The CMY and CMYK color space

    Devices like color printers and copiers that deposit color pigments on paper use a color model that is based on the cyan, magenta and yellow colors. This color model is called CMY and to convert a color from RGB to CMY simply use the following formula:

    [C] [1] [R]
    [M]= [1]- [G]
    [Y] [1] [B]
    go back to RGB and follow the upper instructions
