PRINT JOB AND PROCESS ROLL EVENT TRACKING

摘要

A method and printing press for performing the method is provided for recording print processing conditions on a printed web of a rewind roll during operation of a printing press to print a print job, including associating sensed printing process parameters with tracked locations on the web at which the printing process parameters were sensed such that, for each tracked location, there is an associated set of printing process parameters; storing in memory, for each tracked location, the associated set of printing process parameters; and storing in memory an identification of the rewind roll, and an association of the rewind roll with the associated set of printing process parameters for each tracked location.

1. A method for recording print processing conditions on a printed web of a rewind roll during operation of a printing press to print a print job, comprising:
providing a web roll, the web roll containing a web; unwinding the web from the web roll and passing the web through a printing unit of the printing press; printing on the web with the printing unit as the web passes through the printing unit; passing the web through one or more further processing components to a rewind station located downstream of the downstream of the printing unit; winding the printed web onto a rewind roll located at the rewind station; wherein, as the web passes through the one or more further processing components, further performing the steps of: tracking, with a position sensor, a plurality of equally spaced locations on the web; detecting, using one or more sensors, a plurality printing process parameters of the printing press at a plurality of time points;and further including the steps of
associating the sensed printing process parameters with the tracked locations on the web at which the printing process parameters were sensed such that, for each tracked location, there is an associated set of printing process parameters; storing in memory, for each tracked location, the associated set of printing process parameters; and storing in memory an identification of the rewind roll, and an association of the rewind roll with the associated set of printing process parameters for each tracked location.
