Abstract (en)
[origin: JPH07314635A] PURPOSE: To reduce the disturbance of printing based on vibration by reducing the alteration of structural parts by synchronously performing the same printing operation by at least two printers arranged so as to provide the shift of a mutual phase angle. CONSTITUTION: For example, in the case of a multicolor printing offset rotary sheet-fed press having printers n, n+1, n+2,-n+7, one transfer cylinder is arranged between the impression cylinders of two any mutual printers and the impression cylinder 2 and transfer cylinder 1 made twice in diameter of each printer are formed between plate cylinders 3 and rubber cylinders 4. Since the phase angle between the individual printers is 90 deg. in this case, the same printing operation is generated in the first printer (n) and the fifth printer n+4 at the same time to elapse synchronously. Hereinafter, the same operation is generated even in the second printer n+1 and the sixth printer n+5 as well as the third printer n+2 and the seventh printer n+6.
