Re: [Inkscape-devel] CMYK Proposal
- I think that we should remove the CMS tab from fill&stroke dialog.
Color profiles should be selected globaly for the whole document.
- Then, I think that we should display the palletes and the color
pickers with colors transformed by the currently selected profile.
I made these mockups some time ago (sorry the spanglish :) http://www.ohweb.com.ar/screenshots/Inkscape
My idea was to define the profiles and rendering intents for soft proofing in a per document basis. When I showed JonCruz the mockups, he explained to me that each graphic element in an SVG document can have its own profile, and gave me some reasons of why that dialog was better (which I didn't understand very well at the time and I can't remember now). I don't know any possible scenario where one could need different profiles in the same document, but I guess there is one (I'd really appreciate if someone explains it).
When I worked with proprietary packages I only needed an RGB and CMYK profile for the document, and conversion between RGB and CMYK where performed considering those profiles. Maybe I'm missing some other usage cases that may need another combination.

yes, I know that SVG allows per element profiles, but I cant see any use for this. That is why I suggest global color profile settings.
Could anybody here explain why would be useful for the user to set different color profiles in the same document simultaneously?

You might have some elements which you would only print on output device X, and some you're only print on output device Y? I.e. two different versions of the doc. in the same file for convenience / design reasons?
Just speculating, not saying it's likely or likely to be common.

The visual elements may have multiple fill color definitions with multiple icc(...) values specifieds. This is useful when we want the better color in different outputs. We can use a ICC for a green ball in a old monitor, in a iBook LCD (green is hightlight!), in a home printer and in a industrial printer.
We need the profile of each output to define the ICC fill color to visual elements.
I think that is the better of this feature.
yes, I understand that it is nice to be able to have more than one color profile declared in the same SVG. That's why I built (with your help some months ago in Brasilia) the color profile preferences tab that allows the user to select which profiles are declared in the document.
But I can't see why somebody would use more than one profile ***simultaneously***. I mean, a certain region of the drawing using a certain color profile and the rest using another profile. This is the thing that the spec allows but does not make sense for me.

Oh, I have.
You might have a few layers with a certain CMYK profile, and others with spot-colors (aka pre-mixed single color inks). That's a *very* common occurrence for business customers (logos, brochures, business cards, etc.)
Or you might have a spread that goes from one type of paper to another. Different media like paper type takes a different profile per paper.
A variant of that second case is cut-outs.
ok, so we should have a global setting for default profile (maybe one default setting for each layer?) and then the CMS tab would be the exception case. There still is the need of a global color profile workflow.
