How we proofread PDF documents
We use Adobe Acrobat Pro to open your PDF file, and we then carefully work our way through your document, annotating the PDF with the corrections and other notes as appropriate.When we have finished, we email you the proofed PDF with all annotations showing, and you will simply need to open this file using your PDF editor or Adobe Acrobat Reader.
Having reviewed our suggestions, you then update your document as required, meaning that you retain full control over your content at all times.
If you don't already have Acrobat Reader, please download it free direct from Adobe:
