Hello, I have a feeling this is a stupid question but i'm not having any luck googling for the answer so I will ask here. Apologies but i'm still very inexperienced.
I have just uploaded some christmas card designs, the eps document is in CMYK color mode. I have used the save for web and devices option to prepare my thumbnail previews. It has just occured to me that the preview thumbnail is supposed to be a RGB JPEG. Have I messed up by saving my jpegs from a cmyk document or am I worrying over nothing.
Thanks in advance

Don't worry, "Save for web" process automatically transfers the file into rgb mode.

Thanks a lot for the answer, I had a feeling this was the case so I did a little test but it only put doubt in my mind. I opened my file, changed it to RGB and saved a jpeg and compared the two jpegs. There was a noticeable difference not in the colours but in the shadows in the jpegs, the shadows are black shapes set to multiply blend mode at 30% opacity and in the jpeg saved from the rgb document they appear lighter. Anyway I'm rambling now, thanks for your comment and i'll stop worrying

Actually, you don't have to do much when preparing jpgs. No Photoshop "Save for web" necessary. In Illustrator, just export as jpg, choose resolution, maximum quality, rgb mode... that's all, and that's all in the export dialog.

Thanks Oktal, just to clarify I am choosing save for web directly from illustrator cs5. Ta for the info though
