The ink jet recording apparatus, and image forming method using the photo-curable ink, an ink set using a photo-curable ink-jet recording apparatus and inkjet recording method

摘要

Present invention is an ink jet recording apparatus comprising a light irradiation device for curing the ink by irradiating the optical recording head for discharging a recording medium ink photocurable, the ink that has landed on the recording medium , Using the ink amount of the polymerization initiator in the ink is at most 5% by mass, also in thick film ink amount to be cured by irradiation with light of one is 5g / m ² or more, as a line printer no deterioration of curability in the case of printing at high speed, and also, is that an image forming method, and to provide an ink jet recording apparatus, after the application to the substrate the ink of the photocurable plurality of colors, the ultraviolet irradiation high-speed recording is possible by limiting the amount of UV transmittance of the absorption peak wavelength of the photopolymerization initiator is less than 0.1%, the uncured ink quantity on the substrate, adhesion to a substrate, and cured wrinkle It is to provide an ink jet recording method having improved sense of asperities, the ink jet recording apparatus and ink set.
