this is an interesting query by ptrb in #scribus:
14:01 < ptrb> Hello. I logged onto this channel a few days ago asking
about getting duotone images created
in The GIMP over into Scribus to render correctly into a
spot colour channel I had created.
14:01 < ptrb> I have made some progress on this and wanted to let others
know in case it was useful.
14:01 < ptrb> I haven't totally solved this one yet, bit I did solve it
to the point of being able to do the
print job that I wanted to get done. The workaround was
one suggested on this IRC channell -
to manually select the areas that I wanted to print in
red, make everything in the other
colour (black) transparent by setting opacity to zero,
then make a PDF of that. Then manually
do the same for the...
14:01 < ptrb> ...black. Since it was only a single page job it was
simple enough. So thanks for that one.
14:01 < ptrb> However I did some digging round on the net, and found
some useful definitions of graphic file
types and their properties. This is probably old hat to
others, but after I found what file
types would support transparency and what wouldn't, things
became a bit clearer. It seemed
that EPS file type might work to get the information from
The GIMP to Scribus. I tried saving
the duotone file that...
14:01 < ptrb> ...I created in The GIMP as an EPS file, and then realised
that the SEPARATE+ plugin for the
GIMP already had a feature to save it as EPS. I had to
manually add the file extension. But
the DuoTone did render OK when put into a Scribus Picture
box. The Red in the DuoTone is shown
in the Magenta channel. No problem with that - it works. I
still want to be able to tell The
GIMP that I want a...
14:01 < ptrb> ..."Spot Red" channel to be used, and have that picked up
in Scribus - but this works for now.
14:01 < ptrb> After playing with the Scribus Print to File, and separate
a test file into CMYK channels, I
learned that Ghostview would render the EPS file nicely
and showed four separate pages.
Unfortunately blank at the moment, but that's OK. I will
experiment further and find out what
I am doing wrong there. At least I found a tool in
Ghostview that I can use to view and print
the colour seps.
14:01 < ptrb> This is all being done in XP, using Scribus 1.3.5svn RC2.
Seems pretty stable to me so far by
does anybody have comments on it?
p.s.: i hope that ptrb is registered to this mailing list, otherwise
google may show him the answers when he is going to search for "scribus
gimp duotone" :-)
