PURPOSE: To perform printing while sustaining high resolution by preventing the line width from becoming wide when a thick film circuit is printed on the surface of a board through offset printing.

CONSTITUTION: First time printing is performed while setting the distance between a transfer roll and the surface of board to be printed equal to the thickness of paste transferred onto the surface of a transfer roll. Second to n-th time printings are repeated several times while setting the distance dn between the transfer roll and the surface of board to be printed according to a formula; dn-1≤dn≤dn-1+Tn (n≥2), where dn-1 is the distance between the transfer roll and the surface of board to be printed at the time of (n-1)th printing and Tn is the thickness of paste transferred onto the transfer roll at the time of n-th printing.
