Abstract:
A printed matter production process including ejecting droplets of an actinic ray curable inkjet ink in a heated state through a head to supply the droplets onto a recording medium, thereby forming an image, the actinic ray curable inkjet ink including a polymerizable compound, a photopolymerization initiator and a gelling agent, having a viscosity of from 60 to 200 mPasecond at 25° C. and at a shear rate of 1000/second and showing a phase transition at a temperature of not lower than 25° C., characterized in that the actinic ray curable inkjet ink includes a bifunctional polymerizable compound with a molecular weight of not lower than 400 and with a viscosity at 25° C. of not more than 100 mPasecond in an amount of not less than 75 % by mass of the total amount of the polymerizable compound.
