300 dpi PNGs work quite well in my experience, and not many will take PDF. It helps if you know what size they're to end up and make plots accordingly to avoid any need to resize. JPGs are good for photographs, but not for line work.

For publishers who insist on TIFF format, it should be noted that despite the fact that they're very large, they compress well and can be decompressed by the publisher.
