INKJET IMAGE FORMATION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain images with a high-speed image formation suitability, high gloss and image preservability while folding and splitting at the time of transfer in an inkjet recording device are improved.

SOLUTION: The inkjet image formation method includes a printing process of discharging ink from a recording head to a roll-shape inkjet recording medium with a surface layer which contains a thermoplastic resin and inorganic fine particles, and a post treatment process for melting, softening and forming the thermoplastic resin into a film. When a minimum R in a transfer route is made R(mm), a winding core part of the inkjet recording medium has a diameter of r(mm), a support has a thickness of hb(μm), and an entire ink absorbing layer has a film thickness of hi(μm), an index X is 5.0 or larger. The index X is expressed by X=R2/(r×hi2×hb)×106.
