It would assist us greatly, if you could prepare your appeal documents in the following way:

Type the information using ‘sans serif’ font sizes of at least 11 point. (‘Sans serif’ fonts are easier to read on screen, common examples are Arial and Verdana.)
Use A4 size paper wherever possible.
Print documents on both sides of a page if you want to, but please ensure that the quality of paper is such that images from one side of the page do not show through to the other side.
Use black ink and capitals if you need to write on a document.
Ensure photocopied documents are clear and legible.
Place photographs, maps, plans, etc., in a separate appendix and cross-reference them within the main body of the document. Do not stick photographs to sheets of paper. Put them in an envelope and write the site address or appeal reference number if known on the back.
Bind documents in such a way that bindings can be undone quickly without damaging the document. Avoid using wire or plastic spiral binders.
Avoid using cover sheets, sleeves or other bindings that do not add value or information.
Ensure that the pages of documents are clearly numbered.
Please do not send valuable original documents unless these are specifically requested.
Please do not include post-it notes or other small attachments which might be easily dislodged or lost.
