How to convert cmyk images to rgb without losing colour quality

I am using Adobe Illustrator to design and layout a my webpage. Now that I am happy with it I would like to take it into adobe imageready, and chop it up into slices.

My problem is that I created the original design using CYMK and when I place the image in adobe imageready it converts to RGB and doesn't look right (a bit pale and the colours are all slightly off).

I have found a work around that can produce the correct colours in imageready:

Display image in Illustrator at the correct target size (use zoom control)
press "print screen" button on keyboard
go into image ready and paste from the clipboard.

This looks much better *however* it is not very convenient since you can only take a screen grab of what's actually showing on the screen! Also, due to the way that Illustrator scales images for screen display, there are inconsistencies in some of the stroke widths and so on.

Can anyone tell me a way to place CMYK images from illustrator without this palava?

    Unfortunately, RBG and CYMK are different color spaces, as you are aware, and this can be a problem.

    How are you transferring your Illustrator files to Imageready? I would suggest outputting EPS files from Illustrator, opening them with Photoshop, converting to RGB, and then saving them in your web formats using Photoshop.

    I feel the best way is to convert your illustrator design from CMYK to RGB and edit whatever colours you feel is not right and export as psd. You can then opne it in ImaeReady.

    lherrou - "How are you transferring your Illustrator files to Imageready?" - First I save the document in a native illustrator 9 format, then create a new document in imageready and choose file>place. - This method produces a washed out looking image because of the colour conversion. The other way I do it which reproduces the colours almost perfectly is to take a screen grab (printscreen key) in illustrator then simply paste the image into imageready. Unfortunately this is not ideal because of the way the image is scaled.

    dandeliondream - I tried your suggestion. I changed the colour mode of my document in Illustrator "File>Document colour mode" but suprisingly there was no obvious change in colour, so I saved it and placed it in imageready. Looks much better - thanks.
