Claim 0:
1. An ink set of a radiation-curable ink jet composition containing a polymerizable compound, wherein
the ink set includes a color ink and a clear ink as the radiation-curable ink jet composition,
the polymerizable compound contained in the clear ink contains at least one of Polymerizable monomer A1 and Polymerizable oligomer A2, the Polymerizable monomer A1 having a volume of 0.26 nm3 or more and 0.60 nm3 or less, and an area in the direction of the height relative to a long side of 0.25 nm2 or more and 0.50 nm2 or less that are defined by using the van-der-Waals radius, and
a total content of the Polymerizable monomer A1 and the Polymerizable oligomer A2 contained in the clear ink is 80% by mass or more relative to a total amount of the polymerizable compound.
