Claims19
A method for producing printed matter, the method comprising:
- applying a pretreatment liquid A comprising a resin and a pretreatment liquid B comprising a coagulant to a substrate, each using an inkjet system;
- and
- after the applying of the pretreatment liquid A and the pretreatment liquid B, applying an aqueous inkjet ink to the substrate using an inkjet system,
- wherein the resin in the pretreatment liquid A comprises a water-dispersible resin comprising a water-dispersible urethane resin,
- the pretreatment liquid A and the pretreatment liquid B are jetted so as to land on the substrate in a fixed order, and
- for a first pretreatment liquid that lands on the substrate first between the pretreatment liquid A and the pretreatment liquid B, at least one time difference selected from the group consisting of a landing time difference ΔTX between two dots that are arranged along a main scanning direction and for which a distance between the dots reaches a shortest value among any two dots arranged along the main scanning direction, and a landing time difference ΔTY between two dots that are arranged along a direction that intersects the main scanning direction and for which a distance between the dots reaches a shortest value among any two dots arranged along a direction that intersects the main scanning direction, is at least 10 ms.
