To provide an inkjet printing apparatus that improves the smoothness of an ink surface and improves image quality. Provided is an inkjet printing apparatus for printing a UV curable ink onto a print medium. The inkjet printing apparatus including: an ejection unit configured to eject the UV curable ink; and a UV light source configured to irradiate, with ultraviolet light, the UV curable ink landed on the print medium, the print medium being formed from vinyl chloride. The inkjet printing apparatus further includes a heating unit configured to heat the print medium. The heating unit either heats the print medium to a temperature at which a solvent contained in the UV curable ink landed on the print medium does not volatilize or heats the print medium in a state in which the UV curable ink that lands on the print medium contains substantially no solvent.

Inkjet printing apparatus, inkjet printing method

To provide an inkjet printing apparatus that improves the smoothness of the ink layer surface and improves the image quality. Provided is an inkjet printing apparatus that prints with a UV curable ink, the inkjet printing apparatus including: an ejection unit configured to eject the UV curable ink onto the surface of a print medium; and a control unit configured to control the ejection of the UV curable ink from the ejection unit, the UV curable ink containing a thixotropy-imparting agent, and the control unit setting the viscosity of the UV curable ink to 1 mPa&#xb7;s to 20 mPa&#xb7;s at the time of ejection and to at least 80 mPa&#xb7;s within five seconds of landing on the print medium.

Inkjet printing apparatus and inkjet printing method

To create a printed matter having favorable image quality that can prevent air bubbles from being trapped at the time when a protective film is attached to a medium. A method of creating printed matter includes: an ink arrangement step of ejecting a photocurable ink on a printing face of a medium by an inkjet method so that an average surface roughness of the printing face is smaller than 15 &#x3bc;m and irradiating the photocurable ink with a light to be cured; and a laminating step of attaching the protective film to the medium by bonding an adhesive layer of the protective film to the printing face and a surface of the photocurable ink, and the protective film including the adhesive layer having a thickness equal to or larger than 18 &#x3bc;m and a substrate supporting the adhesive layer.
