Hi,
To make a better image /picture, do nit use JPG format when saving as
picture in PPT. Depending on what image you have I would use PNG/GIF. To get
maximum posiible information I would resize the image in PPT to max
dimension as possible - to make it bigger, then save it as image and then
insert inot Word and re-size it there to smaller dimension.
I was agreeing with you all the way up to "re-size in Word". Word will
often re-sample the image when you do that. It must think that a
3000*2000 image at 72 dpi wants to be 72 dpi when it is shrunk to
300*200 pixels. I find that making the picture the exact right size at
300 dpi in an external editor such as GraphicConverter gets the best
results. There is no point asking Word to do better than 300 dpi. It
will refuse. Bitter experience has taught me never to resize a picture
inside Word. Note. If you change the resolution inside GraphicConverter
in the example above, do not check "rescale". If you do, it will make
the same mistake as Word does. Word does respect the dpi setting that
travels with the graphic, even though GraphicConverter may be set to
ignore it, showing a 3000*2000 72 dpi image, at the same size and
quality as a 3000*2000 300 dpi image.
Secondly, if file size is not a problem, I'd recommend TIFF as the
guaranteed cross platform format for photo style graphics.
Word should deal with PDF for vector graphics, but be aware of the bug
that lies somewhere between Redmond and Cupertino that results in
coarse preview bitmaps of beautiful vector images being sent to print
to PDF.
You can also think about using some vector graphic editor/if that's wector
graphic rather than PPT which would give you more control over images.
Downgrade the image quality while preparing PDF depends on way how it was
set while creating- such as Adobat destiler gives you the oportunity to set
wchich images will be compressed and how much.
Humble print to PDF gives you an opportunity to fool with that too.
Bizarrely, it is the Colorsync menu filters where those settings are
made.
