Well, no disrespect, but here's a different perspective from what Chip had
to offer, although I don't really disagree with much of what he posted
There's no doubt that EPS is the highest fidelity image format to use,
however, the software & hardware must be Postscript compatible in order to
view/print an EPS file. Word *isn't* Postscript-compatible, so if the EPS
doesn't have a TIFF or WMF preview included the image won't display in a
Word doc - it will appear as a rectangular placeholder displaying the name
of the embedded file. Additionally, an EPS without a preview (or "header")
will only print on a Postscript-compatible printer, & most in-house printers
(inkjets & many lasers) are not PS-compatible. If the image contains a
preview, *that* will print to a non-PS device but may not be at the quality
you expect. EPS files are also quite large relative to other formats, thus
increasing the size of the doc that includes them. Long story short, it's
best to use EPS for commercial output only.
TIFF is also high quality & doesn't require PS, but does usually result in a
larger file size than necessary for logos & line art. The advantage of TIFF
is support of millions of colors needed for photo quality, gradients & other
images that require a high number of transitional tones in order to retain
fidelity & detail.
For most logos & line art PNG is the more practical way to go. The file size
is significantly smaller than the others you mention, logos typically use
only a few [solid] colors without gradient effects or multi-tone blending, &
they will view & print effectively on any printer. The key is that they need
to be saved at an appropriate resolution (200-300 ppi) in order to print
well (commercially or otherwise).
As a side note, if the logo is to be used for both web as well as print
purposes you'll be better off having *2* separate copies - a higher res
version for printed docs & a low-res version for web display.
