>From the Creating Single Source Images topic in Flare's help:

"The typical DPI setting for images displayed in an Internet browser
is usually somewhere between 72 and 96. The DPI is automatically set
for online output when you capture the image, depending on the
computer that you are using. However, the DPI setting for printed
output often needs to be higher (say, 300 DPI). "

Actually, a dpi somewhere around 72 to 96 (comparable to the
resolution of computer displays) is the setting that will make screen
captures easily readable in printed output and 100% zoom in Acrobat.

The same 72-96 dpi is also good for browsers since you're viewing the
screen shot on a screen of roughly that resolution.

It sounds like Flare is inappropriately resizing images for PDF.
