<p>The booklet (1) has front (2) and back (3) protective covers between which is sandwiched a printed folded sheet (4). The folded sheet (4) consists of a series of panels (9, 10, 11, 12, 13) that are folded one over another in turn and are then folded together in half about at least one fold line (21) orthogonal to the folding of the individual panels. With this booklet, its overall dimensions when folded can be kept small for example credit card size whereas the printable area of the inner folded sheet is much larger. Moreover, the structure of the booklet is one suitable for in-line production.</p> |
