Creating CMYK Prepress PDFs with Inkscape and Scribus. tl;dr Inkscape cannot export prepress PDFs. Scribus can, though. I’ll show you how. It’s better to work in RGB in Inkscape, and then only convert to CMYK on output from Scribus, or editing all colors one by one in Scribus.

That is a very good question. In Inkscape, color is basically RGB value triplets.

But in order to get precise, and to enable the same color to be seen on different computers, the general idea of color spaces comes into play.

A color space determines how a tuple of data values e. In software, this is commonly achieved through the use vmyk an ICC profile. These are known as profile connector spaces.

To illustrate how this works, consider the case where you need an sRGB graphic displayed on your profiled LCD monitor. This same technique for displaying a graphic is used if your graphic is defined in the Adobe RGB color space, a CMYK colorspace defined by a print industry standard profile e. A common color space for the Internet is sRGB. Adobe and HP created this color space to model the behavior of a typical computer monitor so that in the absence of any color management, the raw RGB values piped to your display hardware will appear more-or-less as the designer intended.


As a working space for artwork not targeted exclusively at web browsers, sRGB is a poor choice due to its limited gamut. And then there are spot colors.

Many designers and thus users of vector art packages often specify spot colors that are precise matches from a book, such as Pantone named colors. The main thing about these is that they are supposed to be fixed single colors of a known appearance. There are two different problems: This is easy – just represent the spot colours with their rgb approximations. The only work is at the interface and colour lookup phase – implementing schemes or palettes solves this straight off.

The second problem is generating PostScript or png with the colours separated correctly. A more sophisticated approach would need to address trapping and overprinting. Export to eps and conversion using perl script pscol from http: At some point, adding color management support should be discussed. I know we were discussing this awhile back when the new color palette was being built.


Where “blah” would be bound to some CYMK color profile.

So we may need to be able to use a device-specific one. Of course our CSS infrastructure alone would need some radical changes before it would deal well with this well. We thus need a mapping from name to color profile.

I think we want a doubly-linked list of definitions, and then we re-create the mapping hashtable or whatever in full when the list changes. We don’t expect the list to contain many entries, so it’s cheap to rescan the whole list.


The reason for storing a pointer rather than just storing the name is to allow for duplicate names in the list. Retrieved from ” http: Navigation menu Personal tools Cmyl in. Views Read View source View history.
