Hello , Team ADOBE , The acrobat pro dc should have a feature which can remove watermarks and headers\footers created by other pdf editor , i know its hard but we should have an option to select an object as watermark and remove it from all the pages , we need to manually remove such watermarks from all the pages , if we can set that kind of algorithm than we can choose which thing to remove from all the pages , it would be good , i have tried the adobe preflight too ,but does not work , so please bring that feature soon.
