I have a problem with pdf app background color. When I open a pdf created by ms word, pdfmaker etc. with Adobe reader -not in full screen mode- the page has a background appearring as thin black frame. I don't want this background color and Adobe reader has no option about changing app background. But when I open pdfs created by openoffice save as pdf option, the outline frame is thick and light Gray, so it is changable. How can I make my ms word created pdfs' frame thick and light gray. Is tehre any solution -including changing pdf file content manually?
I attached two pdfs has different bg colors to show the problem clearly.
