"Warning: When spot colors are used with transparency..."

Can anyone tell me why I'm getting this warning in illustrator:

When spot colors are used with transparency,changing them to process colorsoutside of illustrator can generate unexpected results.

The only thing I can think of is that I used photoshop images with transparency in the doc. How will this effect printing. I've never had this problem before.

Thanks.

Aharon

Your Photoshop file shouldn't be causing the problem, unless it has a spot color channel.

Are you using spot colors in any of your Illustrator drawn objects? (A spot color is any of the swatches in the swatch palette that have a little dot in the bottom right corner).

If your file is destined for web or video, you can ignore the error. If it's destined for print, it's worth paying attention to, as spot colors separate unreliably when used with transparency.

Thanks. I was using partially transparent PSD images. I changed them so that they would be fully opaque, so I'm good for now, but how do I avoid this in the future?

It was definately the PSD images, because as soon as I removed them the message stopped coing up.

Thanks.
