PROBLEM TO BE SOLVED: To provide a diaper production method including a printing process without deterioration of product appearance in inkjet printing of patterns.SOLUTION: A disposable diaper production method includes a printing process in which a pattern group including plural sets of different patterns is printed repeatedly by inkjet printing on a web travelling in a machine direction. In the printing process, individual patterns included in the pattern group are printed in turn in a plurality of printing areas. The width of each of the plurality of printing areas is equal to the dimension of a long side or short side of a planar surface obtained by expanding a diaper. A first blank area extending in a cross direction orthogonal to the machine direction across the web is arranged at least in one of the first printing area, in which patterns are printed at first, and the last printing area, in which patterns are printed at last, among the plurality of printing areas. Inkjet printing is suspended in the first blank area, followed by restarting the inkjet printing to print the pattern group sequentially.SELECTED DRAWING: Figure 1【課題】図柄をインクジェット印刷するとき製品の見栄えが悪くなることの無い印刷工程を含むおむつの製造方法の提供。【解決手段】機械方向に走行するウェブに、インクジェット印刷により複数個一組で異なる図柄を含む図柄群を繰返し印刷する印刷工程を含む使い捨ておむつの製造方法であって、印刷工程において、図柄群に含まれる個々の図柄を複数個の印刷領域に順次印刷し、複数個の印刷領域それぞれの幅は、おむつを平面に展開したときの長辺または短辺の寸法に等しく、複数個の印刷領域の内、図柄が最初に印刷される最先印刷領域と、図柄が最後に印刷される最終印刷領域との少なくとも一方に、機械方向に直交する交差方向に延在してウェブを横断する第１空白域が配置され、第１空白域においてインクジェット印刷を休止した後、インクジェット印刷を再開して図柄群を順次印刷する。【選択図】図１
