Hi,
Which way do you import your presenatation to PDF? Here are the steps,
hope these helps.
steps:
Open the PowerPoint file.
Select Print from the File menu.
Pull down the "printer" menu and choose Adobe PDF as your printer.
Click to enlarge
Set Printing Options, if needed. If you need to create a PDF of a
presentation for handout purposes you may want to print out 4 or 6
pages per slide as to maximize usability and print costs. To do this
you will need to select "Handouts" in the "Print What" pull-down menu,
then choose the "Slide per page" option (all within the Print dialog
box).Click to enlarge
Click OK. Acrobat will prompt you to give your file a name, and it
will save it on your hard drive as a PDF file.
All is done; just take into account that such operation may take a
while, depending on the length and on the weight of your presentation.
At the same time, you can convert your PowerPoint to PDF or Flash by
some Converters.
