Indesign is more of a collaging program than an art program unto itself.

You can click on swatches to make them RGB. Then you could do a batch automate in Photoshop, converting the placed images to CMYK. It's very slick, try it.

If you're ultimately going to export, you can continue to work in CMYK, then set the PDF or JPEG or whatever as RGB while exporting.

What is the end result of this project?

Just a warning: any automated CMYK to RGB conversion is going to be a bit off anyway, so doing it by eye may be your best bet. If you don't care, just shift-select the colors in the Swatches palette and double-click on one of the highlighted ones. The group options window will appear, then choose the color mode. I think that's it.

There are color managment options you can choose, but that's a larger, separate issue.

Neither RGB nor CMYK is an absolute space. That is, they both only exist in reference to some particular parameters. So any conversion you do becomes a color management issue. You can of course ignore the issue, but that doesn't mean that color management stuff won't factor into the conversion: it's just that you won't control it.

Of course, depending on the nature of the job, this may not be particularly critical.

To echo John B, what is it that you are trying to achieve by switching to RGB? How will this document ultimately be output or in what form will it be viewed?

If you are going to post this job on the web consider the export option to GoLive. At the very worst you will have web compatable files you can use with whatever program you compose your website with.

Thanks for all the replys, its an advert for a newspaper, but it turns out that one newspaper in particular has an RGB workflow. Ill be doing quite a few ads over the coming months and becuase most papers bar this one are cmyk, I was wondering if there was an option to just convert all colours to RGB.

I dont know how common it is to have an RGB workflow, especially for a news paper but this is directly from their specifications sheet:

"NO CMYK images, only RGB - Independent Newspapers maintain an RGB ICC Profiled Workflow."

For the moment Im just going to export the ad as an .eps. and select the file as RGB when doing so.

Thanks again,
David.
