To provide a printing method capable of suppressing generation of beading, and acquiring a recorded matter having excellent scratch resistance, glossiness and adhesion properties.SOLUTION: There is provided a printing method which executes to a non-permeable substrate, a primer application step, a color ink application step for applying a color ink to a region to which the primer is applied, and a clear ink application step for applying a clear ink to a region to which the color ink is applied, where the primer includes a cationic resin, a polyvalent metal salt, and a diethylene glycol alkyl ether-based organic solvent. The color ink includes resin particles whose glass transition temperature (Tg) is less than 0°C, and an organic solvent expressed by a following formula (1), the clear ink includes resin particles whose volume average particle diameter is 50 nm or smaller and the organic solvent which is expressed by the following formula (1), and a dry film of the clear ink has the glass transition temperature (Tg) in a range of 50°C or greater and less than 0°C.(In the following formula (1), R1 expresses an alkyl group whose carbon number is 1 or greater and 4 or smaller.)SELECTED DRAWING: None 【課題】ビーディングの発生を抑制し、優れた耐擦過性、光沢性、及び密着性を有する記録物を得る印刷方法の提供。【解決手段】非浸透性基材上にプライマ付与工程と、前記プライマが付与された領域にカラーインク付与工程と、前記カラーインクが付与された領域にクリアインク付与工程を有する印刷方法であり、前記プライマが、カチオン性樹脂、多価金属塩、及びジエチレングリコールアルキルエーテル系有機溶剤を含み、前記カラーインクが、ガラス転移温度（Ｔｇ）が０℃未満の樹脂粒子、及び下記一般式（１）で表される有機溶剤を含み、前記クリアインクが、体積平均粒径が５０ｎｍ以下である樹脂粒子、及び下記一般式（１）で表される有機溶剤を含み、前記クリアインクの乾燥膜は、５０℃以上及び０℃未満にガラス転移温度（Ｔｇ）を有する印刷方法である。JPEG2024011486000022.jpg34110（ただし、上記一般式（１）中、Ｒ１は、炭素数１以上４以下のアルキル基を表す）【選択図】なし
