    Hi, I downloaded a pdf file from the web and then it seems to me as white, but when i try to print, then i found that printing took more time to print the lines. I checked the page printed and saw that it is not ordinary white, but having a bluish white tinge in the background colour, so by printing this colour also the printing takes time.
    Is there any free tool which would allow me edit the colour to natural, as automatic paper colour, by erasing the background colour of the pdf. I suppose, that it is an encrypted pdf doc. Any solution, in this regard will be very much appreciated
