Once you have the profile, the CMS tab in the fill/stroke dialog allows you to choose the colorspace for each object and select your desired CMYK values. If you do that and take the SVG file to Scribus, the CMYK values will be honored. Regarding the spot inks, as far as I can remember you can use the auto palette for adding swatches that work "globally" in the document, but since that's done by custom gradient definitios they don't survive the import to Scribus as spot inks. It's not really a problem, since the color of a spot ink is meaningless. The color of spot inks is just a visual aid for you to pick them, but the printer will produce a separate plate for them that has to be inked with the right color. So, don't worry about spots in inkscape then. Just use a regular RGB color and when you import the SVG to Scribus, go to the colors manager and turn that RGB swatch to a spot ink, using the name of the desired ink so it's reflected in the PDF output. The printer will know what to do with it. I run a small graphic design firm, and I send files to printshops almost daily. Personally, I don't even care about doing anything in CMYK in Inkscape. I do everything in RGB, and let Scribus to create the separations. Spot-only works are the exception, of course. But since printing 3 spots is usually as expensive as printing process, most of the jobs end up being just process, with a few exceptions. CMYK+Spots is not very common as one would expect, but it's not a problem if you use the intermediate binding process I just described. You do everything in RGB, and if something has to be printed in a special ink, you can mark the RGB swatch as spot in Scribus and it will take care of it. In my experience, properly color managed RGB > CMYK conversions are pretty reliable. Designers usually think that a special CMYK combination is a bullet-proof method to get exact colors, but that's not true: a certain CMYK combination is tied to a specific press setting (plate order, screen angle, stock type and quality, etc.) Gez.

I would really like to know how you can convert the colorspace of an svg file, I have exported a CMYK file exported from Illustrator but it has not retained its colourspace. AFAIK editing the xml colour tag in a text editor is the only way to get the svg file to include CMYK or spot colour info, please could you share your method of you do this. > > > > I agree, but CMYK is not covered in the svg > > standard.

Thanks John Culleton, My current work around is to do just that or in most cases I change the colourspace of the pdf (including and especially images) using moonshiner. It doesn't always not retain CMYK colour values for vector objects, it is an extra step I would like to avoid. I was wondering if anyone else has been successful in using Ghostscript to convert the colourspace of a PDF, but integrated into the export dialogue maybe as a plugin. Its a slight hassle to import an SVG file, update the CMYK info on each object,export to PDF, send the file to my local printer, do a proof print with them, change the colour again in Scribus, export to PDF. I guess I will just have to continue along this way of doing things, until I have figured out how to what I want myself :) Please forgive if this email looks odd, I'm still looking for a mailing list reader to respond to posts on the list.

Actually SVG does allow for proper CMYK, as does Inkscape. It is just that the export path we use (Cairo) does not support CMYK.

CMYK in PDF from Inkscape
by Judah 24 May '14

24 May '14

Hi all I have been using inkscape for a while now, my only problem has been a lack of native CMYK (and spot color) support for PDF's from Inkscape. I was wondering if there is way to get this piece of software (moonshiner.sourceforge.net) to work with Inkscape esp in the "Save as" pdf dialogue? I checked it with an old version of <adobe/> software I have and the resulting file is definitely in a CMYK color space.

Hi Nathan, sorry for the late reply, Im waiting to have it to reply. > Ok, the tangents do look correct. I think the problem is that you > need to find the osculating points on the curved path fillets. There > is a toy for this (called fillet-minion). See if that makes for nicer > fillets. You are ok, oscilating point is wrong. I surf into the 2GEOM toy filet-mignon, i do about but it give me the strange results pointed by Cale Gibbard in the #3 of this launchpad bug https://bugs.launchpad.net/inkscape/+bug/202751 Finaly i adopted the Cale solution in the same bug https://launchpadlibrarian.net/12692602/rcp.svg Soon I comit the new code. I have a extra problem related to time values on curves, I find that not straight lines have his time values based by his handles instead the distance along it. My cuestion is: Any way to know a point at a distance based time value? Sorry if not explain so well. Regards, Jabier.

Authoring a multipage document using Inkscape
by Steve Litt 14 May '14

14 May '14

Hi all, I have a 2 page document (an evaluation form), and because spacing was very important, I used Inkscape instead of LibreOffice, LyX, LaTeX, etc. This two page document must print on both sides of the paper, so I'd imagine it must end up as a PDF. http://sourceforge.net/projects/inkscape-pages/ seems to indicate that I can do this natively in Inkscape by installing a plugin. I'm a little worried ways that a plugin might affect my normal Inkscape usage. http://wiki.inkscape.org/wiki/index.php/Multipage itself indicates that Inkscape itself doesn't implement multiple pages, because the current SVG spec doesn't support it. http://www.inkscapeforum.com/viewtopic.php?f=5&t=519 reiterates that current Inkscape doesn't support multiple pages, and suggests I use two different Inkscape docs, and desktop publish them with Scribus. All I really need is a 2 page portrait letter-sized PDF, and I'll figure out how to print it duplexed. I have no problem with making two different Inkscape docs. I'm a little concerned about putting letter-sized SVG's into Scribus or LibreOffice or any other "container". Anyone have any ideas of the best way for me to make a 2 page PDF out of one or two Inkscape files?

Hi Nathan. I do a deeper look. ///////////////////////////////////////////////////////////////////// El mar, 13-05-2014 a las 03:40 +1000, Nathan Hurst escribió: 1) to my old astigmatic eyes the tangents do not look like they are > quite matched, are you sure you have the tangent code correct.

Maybe the problem is how far is the tangent handle from a node, but there isn`t a perfect way to determine, it depends from case. I use the nearest point to the tangent from a point placed at a half distance from the real knot filleting to the original cusp node. Here are some pics about how it works: http://sta.sh/28yrjqkdiw1 ////////////////////////////////////////////////////////////////////// 2) can you add fillets with smooth curvature variation (e.g. cornu > spiral, spiro, and I recall there being a 2geom toy that demonstrated > something like that). > /////////////////////////////////////////////////////////////////////// I see about it in power stroke code, I realy do the code but finaly removed, think isnt interesting in one curve path, because it increase the nuber of nodes of the resulting path because you need to pass the cubic values of the handles as points, because the incoming and outgoing curve need to be unchanged. This is my opinion but if anybody want to tell me about, i could change ;) Thanks Nathan for the feedback.
