ABSTRACT:
FIELD OF THE INVENTION
The invention relates generally to printing presses, and more particularly to the control of a printing press using parameter change commands.
RELATED TECHNOLOGY
In a typical lithographic printing press various parameters are monitored and varied as necessary to control the operation of the press. Such parameters include ink and water values, register, and web speed and web tension. A graphical user interface (GUI) is often used in modem presses for parameter control. Parameter control is effected through series of manual mouse movements and clicks and keystrokes. Repetitive operations performed on a press require repetitive manual sequences of parameter change inputs on the GUI. Presetting of press functions is known, whereby preset machine state is stored and then called up to restore the press parameters to the preset state.
SUMMARY OF THE PRESENT INVENTION
The present invention provides for automatic input of parameter changes on a printing press. At least one sequence of parameter change inputs are recorded, for example via a GUI, and may be played back at later time so as to control the printing press.
The present invention also provides an apparatus for automating input of parameter changes on a printing press, the apparatus comprising a recording and storage device for recording and playing back at least one sequence of parameter change inputs, and a processor for controlling the recording and playing back of the at least one sequence of parameter change inputs.
