Abstract
Apparatus and method particularly suitable for use with the closed loop color to color registration system of a commercial web printing apparatus providing automatic monitoring of user selected press conditions and disturbances and corresponding user defined outputs. The apparatus comprises a processor and other hardware for detecting press conditions and disturbances, for permitting operator selection of press conditions to be monitored and for permitting operator assignment of selected press conditions to a selected output port. Multiple types of outputs can be selected for each assigned port including latched, non-inverted, inverted, pulsed and delayed outputs. The selected press conditions are monitored and the selected output type is generated on the assigned port in response to occurrence of the selected press condition. Temporary and permanent masks may be assigned to any selected condition to inhibit output and a selection of active time windows may also be specified.
