Abstract
An image recording device has: a first recording head which discharges a first ink for a first image forming process; a second recording head which discharges a second ink for a second image forming process; a curing section which cures an ink on a recording medium; and a controller which controls the curing section to cure the first ink on the recording medium, and controls the second recording head to start discharging the second ink after a conversion of the first ink on the recording medium becomes not less than 30%.
Claims25
An image recording device, comprising:
- a first recording head which discharges a first ink for a first image forming process, wherein the first ink is an ultraviolet-ray curable ink, which is cured as irradiated with ultraviolet rays;
- a second recording head which discharges a second ink for a second image forming process, wherein the second ink is an ultraviolet-ray curable ink, which is cured as irradiated with ultraviolet rays;
- a curing section which cures the ultraviolet-ray curable ink on a recording medium, wherein the curing section includes an ultraviolet light source generating the ultraviolet rays to cure the ultraviolet ray curable ink;
- and
- a controller which controls the curing section to cure the first ink on the recording medium, and controls the second recording head to start discharging the second ink after a conversion of the first ink on the recording medium becomes not less than 30%, wherein the second image forming process is a process for a background, and a layer of the second ink has a transmission density not less than 0.15 or an L value not less than 65.
