Formats

This refers to the way In which the document is laid out. The standard layout is portrait – however, the document size and design may lend itself to a landscape format. Multiple formats can be employed to suit the communication piece and budget, including stapled booklets, concertina folding (when a page opens several times), gate fold (often seen in magazines, where an A4 page will open up to become A3), roll fold (often seen in letters when an A4 sheet is folded to DL) etc.
