PURPOSE:To obtain an elongated printed matter by using an existing printing plate cylinder without using any printing plate cylinder that has a large circumference, by a method wherein a plurality of kinds of pattern components are combined to form a composite pattern while setting repeating periods of the pattern components to be shorter than that of the composite pattern. CONSTITUTION:Patterns (a), (b) are printed on a rolled paper 10 by the first printing plate cylinder 8 comprising a printing plate surface 6 in which an effective printing plate surface region 1 is sectioned alternately into non-printing regions 2, 4 and printing regions 3, 5 along the circumferential surface of a form cylinder 7 at regular pitch in the circumferential direction and in which the first group of patterns (a), (b) are provided sequentially in the printing regions 3, 5. Then, other patterns are printed on blank parts of the thus printed paper by using the second printing plate 18 comprising a printing plate surface 16 in which an effective printing plate surface region is sectioned into non-printing regions 11, 13, 15 and printing regions 10, 12, 14 along the circumferential surface of a form cylinder 17 having a circumference different from that of the form cylinder 7 for the first printing plate cylinder 8 at regular pitch in the circumferential direction and in which the second group of patterns A, B, C are provided sequentially in the printing regions. Accordingly, printing is conducted with a long period of repetition of patterns. |
