Abstract:
To provide a printed matter with a printing line having a convex shape formed through a simple method, the printed matter that changes glossiness or brightness thereof according to an observation angle.SOLUTION: A printed matter includes a printed part composed of a plurality of printing lines on a base material. In the printed matter, a convex line width W and a distance D to a neighboring printing line satisfy a relation of 0.08≤W/D≤20.0 in a cross section vertical to a line length direction of the plurality of printing lines. A line connecting: a contact point of an end on one side of the plurality of printing lines and a base material; and a contact point of an end on the other side of the plurality of printing lines and the base material forms a convex curve upward from a plane of the base material.
