Abstract:
A recording method in which, while a recording head, having a dot forming element array in which N dot forming elements are aligned at constant intervals D in a secondary scanning direction which is a direction of conveyance of a recording material, is reciprocally moved in a primary scanning direction perpendicular to said secondary scanning direction, dots are formed on said recording material by said dot forming element array in accordance with recording data, and said recording material is conveyed in said secondary direction and relatively to said recording head, wherein said N is a positive integer and said interval D is a value obtained by multiplying an interval d between dots in recording resolution in said secondary scanning direction by an even number k, and also said even number k and said dot forming element number N are in prime relation to each other, said recording method comprising steps of:a first step of forming dots on said recording material by said dot forming element array while moving said recording head along a forward-trip path in said primary scanning direction; a second step of conveying said recording material in said secondary direction and relatively to said recording head by a secondary scanning distance of said interval d between dots; a third step of forming dots on said recording material by said dot forming element array while moving said recording head along a backward-trip path in said primary scanning direction; and a fourth step of conveying said recording material in said secondary scanning direction and relatively to said recording head by a secondary scanning distance of (2Nâˆ’1)Â·d; wherein said first to fourth steps are repeated, thereby performing recording.
