I am inserting a logo into poweropoint that needs to work on a number of
different background colours. I have saved the logo as a png file and
inserted into powerpoint at 100% of size it appears and at 144dpi.
Unfortunately curved edges of letters appear jagged - is there a way of
cleaning up the png file and achieving a crisper logo???
 
originally the logo was created in illustrator, outlined and then copied into
photoshop. If it is created originally in photoshop will it help?

I tried it at 300dpi and it is a lot better, but not perfect so thanks a lot
for that.

Keep going then: save at 600 or 1200 dpi and then scale the PNG down to
50% or 25%. That should effectively anti-alias the curved edges.

Thnaks alot that helped too. What I am trying to do is make this work cross
platform. The PC is now looking great but it does not look good on the Mac -
do you know why this would be? I am using Powerpoint X release 1 for Mac.

Is there any chance you're copy/pasting the images into PPT rather than saving
them to disk from Photoshop (or whatever) and using Insert, Picture, From File to
bring them into PPT?

The latter is the One True Way. Mostly.

Copy/Paste with images is Evil. Mostly.
