Inline sensor's e.g. spectral, densitometric measuring sensor, measuring clock pulse preadjusting method for e.g. sheet-feed offset rotary printing machine, involves finding rotational angle for measuring clock pulse from strips position
The method involves inputting a rotational angle position of a dowel pin (7) on a plate cylinder (4). A distance of a fiducial mark (8) from the pin is determined after stretching a printing plate (5), and a rotational difference is computed. A rotational angle position of print control strips (6) is determined based on the rotational angle position of the pin and the difference. A rotational angle for a measuring clock pulse is determined from a position of the strips on the cylinder and the rotational angle until the strips reach a detection area of an inline sensor (10).
