@Numarul7 : Thanks for the timelapse As the DVD is in Creative Commons - By ( David REVOY/ Blender Foundation ) this torrent is totally legal, and I'm even happy if their is 6 seeders to share the huge 8Go of content... not easy !
Just for those who want to pay the DVD, remember the money goes to the Blender Foundation and a little part for me each 1000 DVD sold It always helps. But I'm always happy to see interest around my Dvd. I'm heaven a bit curious why I haven't seen it yet all the content posted by a user on Youtubes or Vimeo. I shall may be do it myself with the agreement of the Blender Foundation:)

Hi Lisa,
Yes, Krita and CMYKTool are two solution for CMYK convertion. I didn't get the time to test it in depht the CMYK in Krita. The main reason is here I still use my licence of Adobe Photoshop CS2 running with Wine to do a conversion at the end, and some color correction for the printing. This allow me a 100% compatibility with the Adobe design/graphic workflow of my clients.

@MrMango : Oui, le code de la palette de la version de Iportnov n'a pas été porté dans le tronc principale de développement ( pour des raisons de mauvaise ergonomie et de propreté du code, il me semble ) et pour l'instant aucune fonctionnalité similaire à l'horizon.
