Often I must send Illustrator artwork to my business associate's PC, who also has Illustrator installed. We're having a terrible time figuring out how to send the files so that she can open them and send them on to printing companies. When I send the files from Illustrator EPS (through Outlook Express), she sometimes receives it in a .dat form or pdf form. While she can usually open it to see the art, it is not still in a form for the printer who requires EPS files. I know there must be a simple solution to this problem! Help, please.
