I found a logo on the net and I saved as a JPEG I sent it to a friend and he changed the name in it and sent back to me as a JPEG. I opened it in Illistrator and saved it as an .AI I sent it to the business card place and they say it does not have the right DPI 300 - 600 I opened it in Illistrator and it shows 800 DPI What am I doing wrong. Can I E-mail it to someone and they could look at it for me? Thanks
