Claim 0:
1. Local gonio-reflection characteristics-acquiring method for acquiring local gonio-reflection characteristics of an image which is aggregation of dots,
wherein sensory glossiness (L) of the image determined by equation (1) is 1.0 or more, the sensory glossiness (L) being determined based on a height of a peak (H), a height of a base (B) and a half width of a peak (W) of a distribution information of lightness with respect to light receiving angle, and the distribution information being obtained by measuring reflected light of a measuring light irradiated into the image, and
wherein the local gonio-reflection characteristics is acquired with a spatial resolution (A), wherein when the spatial resolution (A) is a spatial resolution when the local gonio-reflection characteristics is acquired and when the resolution (B) represents a distribution information of the dots within a region where the sensory glossiness (L) being 1.0 or more, the spatial resolution (A) and the resolution (B) satisfying formula (2),

L=Log((H−B)/W)  Equation (1)

0.8<A/B<10  Formula (2)
