web-offset_ico CR25-CR26Colour register control with MicroMarks


The CR25 register control system has been developed using advanced electronic technologies, such as high-speed matrix video cameras, specially made for the purpose. These have made it possible to enormously reduce the space occupied by the register marks (micromarks) for automatic control of circumferential and lateral color register on web-offset presses in commercial and newspaper printing.
The cameras can be positioned, on request, between the last printing unit and the drier, in order to ensure immediate response to variations in register and thus further reduce the number of waste copies. The cameras read the marks on free paper, unsupported by a roller, with a tolerance of oscillations in the web of ± 7 mm.
