separate+ plugin : how to preserve transparency ?

Hi,
I installed the separate+ plugin, which works fine. However, when I convert an image to CMYK then export it to TIFF format, the transparency is not preserved. I also tried the cmyktool (from black five imaging), but same problem. Any idea how to do this ?
Thanks in advance

I don't think separate+ can do both CMYK and alpha channel. But you can try to do color separation with ImageMagick which does supoport that. Except that it's a comman-line user interface application called 'convert' :)

Thanks, I will try ImageMagick ASAP. While I'm on the subject, do you happen to know which image file format is the best for CMYK + transparency, and compatible with scribus 1.4+ ?

IMO

you should just import RGB images (PNG for example). Scribus will auomatically do the job when exporting for print jobs.

Really ? That would be great.
Let's check scribus's documentation !
