Abstract:
Provided is a recording medium having a test pattern recorded thereon, the test pattern being used for acquiring a landing deviation amount of a recording apparatus including a discharge unit configured to discharge a transparent ink, wherein when light is radiated to be incident on a surface of the recording medium at an incident angle of 45 degrees, and lightness of reflected light from the test pattern recorded with the transparent ink and lightness of reflected light from the recording medium are measured, with each of the lightness being measured at a position perpendicular to the surface, a difference in lightness between the reflected light from the test pattern and the reflected light from the recording medium is equal to or greater than a value predetermined, based on a type of the recording medium.
