PROBLEM TO BE SOLVED: To provide a weight capable of inhibiting such cases that a part of a pre-printed matter is damaged or a part of print is not normally finished due to damage of a card.SOLUTION: A weight 50 includes a lower surface 51 facing cards 11, an upper surface 52 facing the lower surface 51, and at least four side surfaces located between the lower surface 51 and the upper surface 52. The four side surfaces consist of a pair of first side surfaces 53 extending in parallel to long sides 13 of the cards 11, and a pair of second side surfaces 54 extending in parallel to short sides 14 of the cards 11. The first side surfaces 53 and the second side surfaces 54 are configured to incline inward as heading from the lower surface 51 side towards the upper surface 52 side. The lower surface 51 has protruding pieces 55 that protrude downward and extend along the first side surfaces 53. |
