            Description

            The PDF contains a deviceN colour space,

            [/DeviceN [/Cyan /Magenta /Yellow /Black] /DeviceCMYK 25 0 R]

            And the black is specified with /CS0 cs 0 0 0 1 scn. Where 0,0,0,1 represents the CMYK values and more importantly black or K.

            I'm pretty sure the we are reversing the colour information which is why the cyan color is shown instead of black.

              Spent quite a bit more time on this one trying to make sense of some regressions that came about after the change. There seems to be an issue with colour component ordering and the number of names that define the colour. Here is a list of the conflicing files.

              We've done quite a bit of work to reorganize this but there is still some holes in the logic we need to apply. The PDF renders fine as well as our other test files.
