I repeted the experiment using XaraLX, exported the work to xara-eps files format, imported the vector in scribus, publish it to psd X-3 , verify the change in photoshop.All value have -1% (the 0 remain 0) change after exported from XaraLX, for just 1% procent less I think XaraLX is good replacement for Adobe Illustrator.

Inkscape isn't have the goal to make 'for print targeted' documents, have goal to make 'for web' (sorry if I'm wrong). The Sk1 project (www.sk1project.org) will be expected to be a 'print targeted', but isn't in stable/usable stage yet.(again sorry if I make mistake)?Forgive me for my english, please. --- On Tue, 2/23/10, Julian Robbins <julian.robbins at q-par.com> wrote: From: Julian Robbins <[email protected]> Subject: [scribus] Import CMYK colours correcting from SVG/EPS To: scribus at lists.scribus.info Date: Tuesday, February 23, 2010, 3:19 PM Hi We've had some fund and games !! Not directly related to Scribus, but something I only found out about recently is that SVG files only support RGB colourspace not CMYK. Because of this, if using Inkscape, and saving in normal SVG format any CMYK colours are saved into RGB equivalent. If I have a CMYK colour I export as EPS from Inkscape, it too oddly won't save as CMYK, as Inkscape still doesn't support this https://bugs.launchpad.net/inkscape/+bug/171214 Now what's all this got to do with Scribus ? Well although the colours themselves when you import these various files ie SVG, and EPS are ok, the CMYK colour values aren't correct as you expect. But after creating same files in Illustrator, and saving .ai, .svg and .eps files, I would expect the .eps at least to show the correct CMYK values on import into Scribus (using 1.3.6SVN), but it doesn't either. The colour is more or less the same, but the CMYK values vary wildly. Loading up the .ai file into Inkscape also doesn't show the right CMYK values, similar colour match but wrong values. Am I looking at this the wrong way, but how do people using a complete FOSS system actually get a a fully correct workflow with CMYK using Scribus, etc ? Also, can you get the same actual CMYK colour using a different combination of values of Cyan, Magenta, Yellow and Black ? If so, perhaps this is what's happening - same colour, but different (incorrect) make up to achieve it ? -- Kind regards Julian Robbins _______________________________________________ scribus mailing list scribus at lists.scribus.info http://lists.scribus.info/mailman/listinfo/scribus ? ? ? -------------- partea urm?toare -------------- Un ata?ament HTML a fost eliminat???
