PDF Image Resolution

[MicahDB]

I'm having a difficult time meeting a printers requirements and I thought I'd ask if there was any way to tell what the image resolution is on a PDF file.

The images are 300+ when I create the pdf (from Adobe Illustrator CS3), based on their creation instructions, but when I submit they say the images are not high enough quality.

Thanks in advance for any help.

Ahhhh! Nevermind, I found what I was looking for. It is under preflight in the advanced settings of full acrobat.

Thanks,
Micah
