As a follow-up to my last post about Nitro PDF Pro, here’s a little something special for proofreaders who work with PDFs. The wonderfully generous Louise Harnby has made available for free download a set of her own customized stamps which can be imported into PDF editing software. These stamps are, as Louise explains, ‘based on the current BSI proofreading symbols and once downloaded can be imprinted onto the page, giving the proof the appearance of its paper cousin’. There are three files, for red, blue and black. Louise made the stamps to use with Adobe Acrobat, but they should work with other PDF editing software. Louise explains how to get started on her blog.
