such as bingo, comprising a flexographic printing press having a central drum (1)
and a plurality of printing cylinders (2) arranged to print onto material fed into
the press at (3) and exiting at (4). Some of the cylinders (5), (7) and (9) have different
circumferences, each being a multiple of a basic pitch value, and are arranged to

such that the combination of numbers in each table varies in a quasi random manner
over large number of repeats.
