Classification: CPC B  C | IPC B

Claim 0:
1. A liquid discharge apparatus comprising:
a first liquid that generates heat in an absorption wavelength region of an active energy ray;
a first discharger to discharge the first liquid;
a second liquid that starts polymerization in the absorption wavelength region of the active energy ray;
a second discharger to discharge the second liquid; and
an irradiator to irradiate the first liquid and the second liquid with the active energy ray,
wherein another irradiator irradiates the first liquid and the second liquid with an infrared ray before the irradiator irradiates the first liquid and the second liquid with the active energy ray,
the first liquid includes a pigment as a colorant,
the second liquid is a white ink including a photopolymerization initiator in a content of less than 0.1% by mass,
the first liquid is a non-white ink,
the first liquid includes multiple types of colors of inks,
the first discharger comprises multiple first dischargers configured to respectively discharge the multiple types of colors of inks, and
the first liquid is discharged for printing after the second liquid is discharged for printing.
