Design printing related to game design on the front side of each ticket is usually achieved with Flexo printing in which printing is performed with a rubber plate protruded per color. Although Flexo printing is not accurate comparing to currency, flexibility of printing is high. Quality inspection of Flexo printing of a graphic part is performed in a roll unit. For a roll test, tests related to printing quality, such as an oven test, a scratch test, and a test with naked eyes are performed. The oven test is performed to confirm heat-resisting property, the scratch test is performed to confirm a scratch status of scratch and visibility of game data, and the test with naked eyes is performed to confirm a margin and visibility of graphic printing. The accuracy of game data printed is confirmed through accuracy of game data layout design, accuracy of game data creation, accuracy of setting of game data printing facilities, and accuracy of data stored in the printing facilities.
