Re: [vox] Software for Flyers



out of ignorance:
   conceptually at least, isn't there the possibility of
integrating pantone coloring abilities in the GIMP
GUI, and aren't pantone colors CYMK?
   even more broadly, maybe the discussion is about
the idea of serious-workers-in-the-GUI wanting
immediate feedback (never mind display dependability)
wrt printing?

I realize a lot of printing services prefer CMYK format (like, what, is
there a ".cmyk" file that you convert an image into?),
Ok, I now see from the "cmykgimp" project that the file format in question
seems to be "CMYK TIFF" (that is, a TIFF in CMYK colorspace, instead of RBG).


[out of order]
In any case, why does one's front-end application (like The GIMP) need to
do this? Can't this be part of a system-wide printer config, or at least
system-wide printer dialog (e.g., so that other applications can share it)?
"cmykgimp" says it can:

* Convert an RGB image to individual CMYK layers, using specified
source and destination Colour Profiles.

* The RGB -> CMYK conversion is performed with the truly excellent
littlecms library

So in a sense, I guess "littlecms" is doing the work, and the reason
you'd want it in The GIMP (other than so it's one less step, I suppose)
is for some features you currently do get, like:

* Separate CMYK into layers, for tweaking within The GIMP
(both as greyscale, and as Cyan, Magenta, Yellow and Black layers,
blended in 'darken only' mode on top of a white background, for
an editable, approximate representation of the image)

And some features you don't currently get with "cmykgimp":

* Load CMYK TIFFs back in as layers, for editing.
(You must also save a copy in Gimp's native XCF format)
* Embed ICC color management 'profiles' (which I obviously don't really
know anything about) into your images or layers.
(See: http://en.wikipedia.org/wiki/International_Color_Consortium )


<snip>
CMYK has always kind of been the 'silver bullet' for The GIMP, but obviously
I still don't understand why. :^)
So now I wonder... does "cmykgimp" make people happy? (The people who
complained that GIMP didn't do CMYK, at least. ;^) Its new file dialogs
still piss me off.)

It does say it's "rudimentary" and "experimental", so probably not. :^)
