    摘要： Disclosed is a method of exposure-curing an ink layer formed on a recording medium. The layer is made of an ink comprising at least one solvent polymerizable by an acid, a photo-acid generating agent capable of generating the acid as irradiated with light, and a colorant component. This method comprises two irradiation steps. In the first irradiation, the ink layer is irradiated with light by using a light source having a first peak illuminance. The acid is thereby generated from the photo-acid generating agent. The diffusion of the acid is promoted in the layer, curing the ink layer to some extent. In the second irradiation, the ink layer is irradiated with light by using a light source having a second peak illuminance higher than the first peak illuminance. More acid is generated from the photo-acid generating agent and diffuses in the layer, completely curing the ink layer.
