Abstract: In a row of lottery tickets each ticket has variable image printing game data printed onto a base layer on a substrate and a series of covering layers including at least one sealing layer and at least one scratch-off layer. Simultaneously game information is printed as a multi-color digital image for each ticket using a variable image printing system. The game information graphics can indicate different values for different ones of the tickets. The tickets in the row can be of different series for sale to different retailers. The printing system automatically correlates the game data and game information to ensure no registration errors thus allowing much improved variability and allowing the game to take into account both game data and game information in determining a winning ticket.

Abstract: First and second buffer roller pairs are driven such that a sheet conveyed sequentially by a conveying roller pair is overlapped with a standby sheet by shifting in a sheet conveying direction and such that the overlapped sheets standby at a branch path. A shift length in overlapping the standby sheet with the conveyed sheet is set such that the more the number of times of drawal into the branch path of the sheet, the shorter the shift length becomes. Thereby, the shift length between the respective sheets turns out to be a predetermined shift length in overlapping the standby sheets with a final conveyed sheet and conveying the sheets to an intermediate processing tray.
