Re: Removing background color from pdf for printing

Just see if they are willing to send you the ppt files. You'll need to get a copy of PowerPoint if you don't have it; but then you'll be able to print the slides the way you want to.

Otherwise, try printing the PDFs two to a page. That will use somewhat less than half as much toner and the type should still be plenty large enough to read.

Thanks for the information!
My problem is that the pdf files are from several authors: from the professoers of my studying and it will be difficult to motivate them to do anything for a student..... at least not for this version, may be they will do it for later versions. Anyhow i will inform them.
But if there is any possible idea else, like some tool.... please inform me!

i have several pdfs created by powerpoint. The author used a blue background color (changing its saturation throughout the page) in powerpoint. This background is not removeable by options in Acrobat reader 7.0 . Printing of that documents costs a lot of ink or toner. Is there a possibility to get rid of that background? 


Most probably not. If it's only one PDF object (depends on how the PDF
was produced), you may try to use Acrobat and its touch-up tool to
remove the backgrounds. But this task seems very "unscriptable" to me,
i.e., you'll need to do manual work.

Been there. Done that. Unless the most recent version of PowerPoint handles background gradients more gracefully than earlier versions (which I sincerely doubt), the background consists of a lot of horizontal bars. Removing them without disturbing other content of the slide is almost impossible. In addition, if the text is rendered in white, dropped out of the background, removing the background makes the words illegible. And selecting the text to touch up the color can be equally frustrating, especially if it was rendered with a drop shadow.

The only real solution is to get the original PowerPoint presentation and print it to PDF using the Black & White option in the print dialog. Perhaps the author can do this for you if he or she does not wish to part with the PPT files.
