<p>A document is printed with graphical symbols which encode information but are not human readable; the graphical symbols are formed into some or all of a visible element and the shapes of the external borders of several graphical symbols differ from each other in order to achieve a desired appearance for the element. Typically, one or both of the linear dimensions of a graphical symbol can be altered for the appropriate aesthetic effect. Prior art graphical symbols (e.g. glyphs etc.) are generally fixed in shape and hence cannot be modified for aesthetic effect. Instead, they have generally been large and obtrusive blocks which considerably mar the appearance of a printed document. This negative impact on appearance has been one of the major causes inhibiting the uptake of graphical symbol technology for encoding information.</p> |
