Abstract: A clock generator for generating a clock signal for an imaging device serving for transferring image-setting information to a rotatable printing form which includes an input to which an actual value signal dependent upon an angular position of the printing form is applicable, and an output for outputting the clock signal. It further includes a first comparator having a first input whereto the actual value signal is applicable as an analog signal, a second input to which an analog nominal value signal, respectively, representing a nominal value for the angular position of the printing form, is applicable, and an output for outputting the clock signal formed as a function of a result of a comparison between the analog actual value signal and the analog nominal value signal; an imaging device and a printing machine including the clock generator; and a method of generating a clock signal for an imaging operation.

Abstract: A device for fast image data transfer in at least one printing press having at least one RIP, includes a data manager to which image data is supplied, at least one storage unit and at least one imaging unit. A bus system is provided for connecting the at least one storage unit both to the at least one data manager for intermediate buffering of the image data, and to the at least one imaging unit for setting an image. The at least one imaging unit serves for communicating with the at least one storage unit, and for reading the image data directly from the at least one storage unit. A method is also provided for operating the device.
