Abstract
A computerized press control includes a set of counters countable in real time as the associated press cylinder rotates to enable the press control system to readjust the inspection zone, wherein the mark to be sensed on the web can be expected to be found, on a per revolution basis of that cylinder and to dynamically alter the length of the inspection window on a per revolution basis to enable the press control system to control color registration in spite of wide variations in press speed or conditions of the web.
