TIFF + CMYK

[Bug Importer]

Please add support to export to a TIFF with CMYK, Inkscape is one hell of a
vector program. But without the option of being able to export with CMYK
values just makes it impossible to use for professional printing.

Since SVG is inherently an RGB based standard then converting colours to
CMYK would, at best, be hit-and-miss. Certainly, other professional
printing features, such as separation spot colours ain't gonna work.
So I'm not convinced this is achievable in a sensible way. If you are
involved in a PDF workflow then Acrobat Professional would probably do a
better job of converting RGB to CMYK.

The first issue is that there is no single style of TIFF image. The
standard is very complex and different software implements different
subsets of it.

The second issue is that most now are considering PDF "the" format for
professional printing. Currently Inkscape->Scribus->PDF is a strong
workflow for many people. CMYK color values are being added to Inkscape and
Scribus will be passing on use of that.

Workaound is:
  convert image.png -colorspace cmyk -compress lzw -profile /usr/share/color/icc/ISOwebcoated.icc image.tif

Note that you use the correct ICC profile from /usr/share/color/icc/
