Recording medium and method for acquiring landing deviation amount in recording apparatus

A recording medium having a test pattern recorded, 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, the recording medium comprising:

• a first area in which the test pattern is recorded with at least the transparent ink;
• and
• a second area in which the test pattern is not recorded and that is different from the first area,
• the recording medium having a lightness difference between the first area and the second area, the lightness difference being equal to or greater than a value predetermined based on a type of the recording medium, the light difference being defined as a difference in lightness between a reflected light from the test pattern recorded with the transparent ink in the first area and a reflected light from the recording medium in the second area when light is radiated to be incident on a surface of the recording medium at an incident angle of 45 degrees, and lightness of the reflected light from the test pattern recorded with the transparent ink in the first area and lightness of the reflected light from the recording medium in the second area are measured, with each of the lightness being measured at a position perpendicular to the surface, wherein
• the recording medium has the lightness difference equal to or greater than 0.007 as the predetermined value, when L1 is the lightness of the reflected light from the test pattern recorded with the transparent ink in the first area and L2 is the lightness of the reflected light from the recording medium in the second area, and the difference in lightness is an absolute value of a difference between a logarithmic function LogL1 and a logarithmic function LogL2.
