Patent ID: 8662654

Claim:
A printing device comprising: a plurality of heads ejecting ink cured by irradiation of light and arranged in a transport direction of a medium; a plurality of temporary curing light sources provided respectively corresponding to the plurality of heads and respectively irradiating light for temporary curing to dots formed on the medium by the respective heads; and a main curing light source irradiating light for main curing to the dots to which the plurality of temporary curing light sources have irradiated the light, wherein the printing device has a first printing mode that includes ejecting a clear ink from one of the heads placed at an upper stream in the transport direction of the heads ejecting color inks, irradiating the temporary curing light to the clear ink by one of the temporary curing light sources corresponding to the one of the heads that discharges the clear ink, discharging, from one of the heads for discharging color inks, a color ink on the temporary cured clear ink, and irradiating the temporary curing light to the color ink by one of the temporary curing light sources corresponding to the one of the heads that discharges the color ink, wherein the printing device has a second printing mode that includes discharging a color ink from one of the heads for discharging color inks, irradiating the temporary curing light to the color ink discharged in the in the second printing mode by one of the temporary curing light sources corresponding to the one of the heads that discharges the color ink in the second printing mode, ejecting the clear ink on the color ink temporary cured in the second printing mode from one of the heads placed at the lower stream in the transport direction of the heads ejecting the color inks, and irradiating the temporary curing light to the clear ink discharged in the second printing mode by one of the temporary curing light sources corresponding to the one of the heads that discharges the clear ink in the second printing mode, and wherein an irradiation energy of the light irradiated by the one of the temporary curing light sources corresponding to the one of the heads that ejects the clear ink in the second printing mode is smaller than the irradiation energy of the light irradiated by the one of the temporary curing light sources corresponding to the one of the heads that ejects the clear ink in the first printing mode.
