1. An ink set comprising:
a first ink including an ethylenic unsaturated compound and a photopolymerization initiator, the first ink not including a colorant or including a white colorant; and
a second ink including an ethylenic unsaturated compound, a photopolymerization initiator, and a colorant,
wherein the ethylenic unsaturated compound included in the first ink includes:
a monofunctional monomer that is a compound including one ethylenic unsaturated group, and a proportion of an amount of the monofunctional monomer to a total amount of the ethylenic unsaturated compound included in the first ink is 95.0% by mass or more; and
a silicone compound having an ethylenic unsaturated group,
wherein the ethylenic unsaturated compound included in the second ink includes:
a monofunctional monomer that is a compound including one ethylenic unsaturated group, and a proportion of an amount of the monofunctional monomer to a total amount of the ethylenic unsaturated compound included in the second ink is 95.0% by mass or more; and
a silicone compound having an ethylenic unsaturated group, and
wherein, when a static surface tension of the first ink at 25° C. is defined as T1 and a static surface tension of the second ink at 25° C. is defined as T2, a value calculated by subtracting T1 from T2 is 1 mN/m or more.
