Zusammenfassung:	A lottery ticket comprising a substrate with a background image printed 279 in a first area, variable indicia 273 printed in a second area, a Benday pattern 276 printed on the first area which creates a void pantograph which can be seen by an unaided human eye when copied and a scratch off coating. The Ben Day pattern may be plate printed using a varying process colour and the background may be a pattern. The Benday pattern may be visible using a lenticular lens. Also disclosed is a lottery game with first and second tickets each with Benday patterns formed from dye-based ink which may be a sine wave and use UV ink. The background may also be a solid colour or an embedded image. The systems provide security protection against alteration or copying.
