Description Stede Bonnett 2008-04-21 06:47:47 UTC 
PDF: Trying to output a Duotone PDF with 'tiffsep' does not create a spot color
file (although the color is identified to StdErr). To test I placed this same
file into another document with CMYK components and additional spot colors and
found that whatever the last identified color is will not be output.
(Using InDesign I had an overall background color which was listed first, the
Duotone, which came second, and two different spots from another placed PDF file
which were last. The very last color did not output a separation.)
PS: If I use a PS file as the input (converting the pdf with Acrobat 8) it
creates the separation files for all spot colors, but the channel with the
duotone image data is blank.
Output to 'psdcmyk' has the same results, missing (or blank) channel in the
resulting file.

This is the test file I used to work on this issue. CMYK+4 spots.

Current development version of Ghostscript has
tiffsep device working correctly in 64-bit builds.

32-bit build has some problems, which are tracked in the bug 692318.
