A stapled booklet is the quick, easy and affordable way to present your printed newsletter or magazine.
When preparing artwork you should be aware that as the number of pages increases the pages close to the centre of the book form a V which we trim off when we bind the book. This V is called shingle and the effect on the position of the artwork relative to the trim is called creep.
Most designers accomodate this by allowing sufficient margin but some choose to calculate the effect and adjust ech printers spread.
