Empty printing is accomplished by the following method; carve a pattern on a convex printing block and carve the negative image on a concave printing block, place a ground paper on the concave wood block, place the convex wood block over it and apply pressure, this produces a pattern that stands out, and this is the same technique used to emboss images on paper today.
空摺りは、同じ画の版木を陽刻の凸状のものと、陰刻の凹状の二版に彫り分け、陰刻の版木の上に地紙を乗せて、上から陽刻の版木を重ねて圧をかけると、凸状の形が浮き出る技法で、今日のエンボスと同様な形押しの技である。
