Abstract:
A method of setting registration, with detection of the entry of a printing substrate (2) into a printing machine (1) and calculation of the beginning of digital production of color separations (3, 3â€², 3â€³, 3â€²â€³) to achieve an in-register position of the color separation prints (4, 4â€², 4â€³, 4â€²â€³) on a printing substrate (2), wherein the printing substrate (2) is detected before it enters the printing machine (1) and, following this detection, the relative positions of the color separations (3, 3â€², 3â€³, 3â€²â€³) are calculated, and wherein precise detection of the leading edge (5) of the printing substrate (2) is performed as it enters the printing machine (1) and made the basis for determining the starts of the production of the color separations (3, 3â€², 3â€³, 3â€²â€³), their relative position having been precalculated.
