Not so long ago, the federal court clerk refused an efiling and requested it be refiled… the problem? The pleading had a scanned signature on it which showed up in nice blue ink and the federal efiling system required black and white. A quick attempt to save the document as black and white from Adobe Acrobat Pro failed, as did the attempt to print as black and white back to Acrobat Pro…. grrr. However, opening the document in Mac OS X’s built in Preview provided the solution… Save as gives the ability to save as black and white, even though the $300 Acrobat Pro refused to do so!
