PROBLEM TO BE SOLVED: To provide a gravure offset printing method capable of forming a fine wire pattern in a favorable precision without adjusting the composition of a printing paste.SOLUTION: In the provided gravure offset printing method, the line width of the second fine line portion 23 of a recessed portion 21 is set to be greater than the line width of the first fine line portion 22 thereof by at least 10 μm. On an occasion for transferring, onto the surface 6a of a blanket 6, a printing paste P filled into the second fine line portion 23 extending along a direction orthogonal to the printing direction, the pressure between the gravure plate 11 and the blanket 6 is easily dispersed. As the line width diminishes, therefore, the shape degradation of a fine wire pattern formed by the second fine line portion 23 tends to become more conspicuous than that of a fine wire pattern formed by the first fine line portion 22. In a case where a line width greater than the line width of the first fine line portion 22 is secured for the second fine line portion 23, therefore, an entire fine wire pattern can be formed in a favorable precision without adjusting the composition of the printing paste. |
