Disclosed is a process for producing a printed matter, which comprises ejecting droplets of an active ray-curable ink in a heated state through a head to supply the droplets of the ink onto a recording medium, thereby forming an image, wherein the active ray-curable ink comprises a polymerizable compound component, a photopolymerization initiator and a gelling agent, has a viscosity of 60 to 200 mPa·sec at 25°C and a shear rate of 1000/sec and can cause phase transition at a temperature of 25°C or higher. The process is characterized in that the ink contains, as the polymerizable compound component, a bifunctional polymerizable compound having a molecular weight of 400 or more and a viscosity of 100 mPa·sec or less at 25°C in an amount of 75 mass% or more relative to the total amount of the polymerizable compound component. The process enables the production of a printed matter that has excellent ink ejection stability, can be printed at a high speed, has a highly precise and highly stable image formed thereon, and rarely undergoes deformation. Also disclosed are: a printed matter produced by the process; and an active ray-curable inkjet ink which can be used for the printed matter. |
