The most popular style of comparison chart made at Whitney Woods comprises of 2 or 3 discs with die-cut windows that are fastened at the centre with a metal eyelet. The optimum size is no wider than 160mm diameter as anything over that size has to be assembled on a 100% manual operation which adds to the price. Ordinarily the discs are printed on both sides on 350gsm silk board.
