Export only seems to generate sRGB TIF (2010-04-23 02:03 by Jonathan #50221)

Having done a separate+ (Gimp 2.6), which generated the four grey-scale layered image separate->export was prepared to generate a TIF, but it said that it was a singe layered RGB TIF, even though I selected CMYK profile. It loads into the Gimp (on another machine on the network) as a perfectly normal RGB colour TIF. How do I get a CMYK TIF to save?

Preinstalled TIFF file plug-in doesn't support CMYK file. If you try to open CMYK TIFF file with the GIMP, it accesses as if file is RGB.
We provide a small CMYK TIFF import plug-in named "separate_import". This plug-in imports CMYK TIFF file (JPEG/PSD files are not supported) and generates a pseudo-composite document.

So you are saying that the export does produce a real CMYK file, but that the
'standard' GIMP accesses it as if it is RGB?

Where is this in the package? I couldn't find it ...

Thank you for your work!

Yes.
GIMP cannot load the CMYK TIFF file correctly, but no error (or warning) messages are displayed.

What OS do you use and how do you install Separate+?
If you installed Separate+ correctly, you can call the separate_import plug-in via "File -> Create -> From CMYK TIFF".

I installed Separate 0.5.8 for Gimp 2.4.
I works, but when I select Separate-> Separate from the Image menu, it does not show any choices for the Destination Color Space
