PURPOSE:To prevent large undulation by averaging the adhesion amount of the ink in the periphery of a guide line, by printing transparent ink on the non-printing parts on both sides of the guide line in a thickness not exceeding the thickness of the ink coating of the guide line. CONSTITUTION:Transparent ink 5 is printed on the non-printing parts on both sides of a guide line 2. The thickness of the transparent ink 5 is made equal to or thinner than that of the ink coating of the guide line 2 and, especially, when said thickness is set to the value between the thickness of the ink coating of the guide line 2 and the average thickness of the ink coating at the part of a pattern 4, the formation of a small protruding part is confined in the vicinity of the guide line and, as a result, the generation of winding irregularity or flare is prevented. When the guide line 2 is printed in a broken line state and the thickness of the transparent ink is also made equal to the average thickness of the ink coating at the part of the pattern 4, the adhesion amounts of ink at the parts of the guide line 2, the pattern 4 and the transparent ink 5 are averaged and enevenness is not almost generated even when printed matter is taken up in a large quantity.
