Abstract
A printing apparatus includes: a first nozzle which ejects a first ink used to print an image on a medium and cured by irradiation of light; a pre-curing light source which emits a pre-curing light to dots formed as the first ink ejected from the first nozzle is landed onto the medium; a second nozzle which ejects a second ink used to coat a surface of the medium and cured by irradiation of light onto the medium after being irradiated by the light from the pre-curing light source; and a main-curing light source which emits a main-curing light to the medium, wherein the irradiation energy of the light emitted to a unit area of the medium from the pre-curing light source is changed according to whether the second ink is ejected from the second nozzle.

A printing apparatus comprising:
- a first nozzle which ejects a first ink used to print an image on a medium and cured by irradiation of light;
- a pre-curing light source which emits a pre-curing light to dots formed as the first ink ejected from the first nozzle is landed onto the medium;
- a second nozzle which ejects a second ink used to coat a surface of the medium and cured by irradiation of light onto the medium after being irradiated by the light from the pre-curing light source;
- and
- a main-curing light source which emits a main-curing light to the medium,
- wherein irradiation energy of the light emitted to a unit area of the medium from the pre-curing light source is changed according to whether the second ink is ejected from the second nozzle.
A printing method using a printing apparatus which includes:
- a first nozzle which ejects a first ink used to print an image on a medium and cured by irradiation of light;
- a pre-curing light source which emits pre-curing light to dots formed as the first ink ejected from the first nozzle is landed onto the medium;
- a second nozzle which ejects a second ink used to coat a surface of the medium and cured by irradiation of light onto the medium after being irradiated by the light emitted from the pre-curing light source;
- and a main-curing light source which emits main-curing light to the medium, the method comprising:
- changing the irradiation energy of the light emitted to a unit area of the medium from the pre-curing light source according to whether the second ink is ejected from the second nozzle;
- and
- emitting the light from the pre-curing light source to the dots formed as the first ink is landed onto the medium.
