  • Patent number: 11626043
    Abstract: A multilayered printed matter includes a group of print layers formed on a medium. The group of layers include a front layer and a back layer on which patterns are printed, a white layer, and a black layer. The white layer is interposed between the front layer and the back layer to conceal the back layer to be invisible from the side of the front layer. The white layer reflects incident light from the side of the front layer to allow the front layer to be visible from the side of the front layer. The black layer is interposed between the white layer and the back layer to conceal the back layer to be invisible from the side of the front layer. In comparison between the black layer and the white layer that are equal in thickness, the black layer exerts a higher light blocking effect than the white layer.
