Abstract:
The present disclosure relates to a playing card, where a suit and a rank are printed on one surface of a card base sheet, a back pattern is printed on a back surface, an intermediate layer having a black layer or a color layer similar to black is provided on the card base sheet to make transmission of visible rays difficult, and ink containing no carbon is used for printing the suit and the rank. The intermediate layer is configured to prevent transmission of visible rays from the back surface. The suit and the rank printed with the ink containing no carbon are configured to transmit infrared rays. The intermediate layer and the suit and rank printed with the ink containing no carbon are configured such that it is difficult for both the visible rays and the infrared rays to distinguish the suit and the rank from the back surface.
