To provide a printing method which can improve a printing speed while suppressing blocking even in a case where an aqueous ink is used, and thereby reducing a printing cost; and a method for producing a printed resin film for packaging.SOLUTION: The printing method according to the present invention includes: forming a plate cylinder in which flat cells each having a depth of 11 to 16 μm are arranged in a honeycomb shape, and the number of lines are 200 to 350 LPI; and performing printing on a base material with the use of an aqueous ink. Here, it is preferable that a width of an inter-cell region between the cells is in a range of 12 to 16 μm.SELECTED DRAWING: Figure 2 【課題】水性インキを使用する場合であってもブロッキングを抑制しつつ印刷速度を向上させることができ、印刷コストを低減できる印刷方法並びに包装用樹脂フィルム印刷体の製造方法を提供する。【解決手段】本発明に係る印刷方法は、ハニカム形状で平坦な深さ１１〜１６μｍのセルが配列され、線数が２００〜３５０ＬＰＩである版胴を形成し、水性インキを用いて基材に印刷することを特徴とする。ここで、前記セルの間のセル間領域の幅が１２〜１６μｍの範囲内であることが好ましい。【選択図】 図２
