Using #AA0000 in print and on screen

On screen this value is exact. In print it is an approximation: the cyan magenta yellow black figures above come from the standard conversion formula, and the colour a press actually lays down depends on that printer's own profile, the ink set and the stock. For anything where the shade matters, ask the printer for a spot ink rather than accepting a process build.
