--- Comment #1 from Adrian Johnson <ajohnson at redneon.com> ---
The reason CMYK(0,0,0,1) does not map to RGB(0,0,0) is CMYK(0,0,0,1) is not the
darkest CMYK color. CMYK(1,1,1,1) is the darkest (see
https://en.wikipedia.org/wiki/Rich_black).

Testing with CMYK(0,0,0,1):

Adobe Reader: RGB(35,31,32)
Ghostscript: RGB(34,31,32)
Poppler: RGB(35,31,32)


Testing with CMYK(1,1,1,1):

Adobe Reader: RGB(0,0,0)
Ghostscript: RGB(0,0,0)
Poppler: RGB(0,0,0)


Poppler is outputting exactly the same colors as Adobe Reader.
