CMYK color space with Adobe Illustrator export figure

Hi, I am exporting a large sequence of vector graphics to be animated in Adobe Flash afterwards. For various reasons, Adobe Illustrator files are best for the import. However, the AI files generated from Matlab (e.g. 'print test.ai -dill') always have the CMYK colorspace (not RGB - although this is the one selected by default in the figure print setup). This distorts the original colors. Is there any way to change this in Matlab? (As a workaround, I am using -despc and converting later with another graphics program to AI, but this is too time consuming). Regards, MT
