Apparatus for monitoring a print result in a rotary printing press
Apparatus for monitoring a print result in a rotary printing press, includes a web monitoring system including a matrix camera ( 20 ) that is movable in transverse direction over a web printed in the printing press, the matrix camera being adapted to capture an excerpt of the printed image in synchronism with a repeat of the printed image during a print run, an inspection system for a complete inspection of the printed image, the inspection system including a line camera that extends over the entire widths of the web, and an integrated control desk for the web monitoring system and the inspection system.
1. An apparatus for monitoring a print result in a rotary printing press, comprising:
a web monitoring system including a matrix camera that is movable in transverse direction over a printed web printed in the printing press, the matrix camera being adapted to capture an excerpt of the printed image in synchronism with a repeat of the printed image during a print run,
an inspection system for a complete inspection of the printed image, said inspection system including a line camera that extends over the entire width of the web and adapted to capture a complete image of the printed web and storing the same in digital form which is linked with positional information indicating a location of a respective image area in a longitudinal direction of the web,
an integrated control desk for the web monitoring system and the inspection system, and
a data processing system adapted to automatically detect errors in the image printed onto the web by analyzing the image captured with the line camera and to display the errors visually on a screen of the control desk, the data processing system being adapted to indicate defective image areas by showing a mark on the screen and to interpret a strike of a user onto this mark as a command to display the image area where the error has been detected on an enlarged scale using the matrix camera.
2. The apparatus according to claim 1 , wherein the control desk has a touch screen for selectively displaying at least one of:
an image delivered by the matrix camera and
an image delivered by the line camera
and for inputting operating instructions.
3. The apparatus according to claim 1 , wherein the matrix camera has an optical zoom function.
4. An apparatus for monitoring a print result in a rotary printing press, comprising:
a web monitoring system including a matrix camera that is movable in transverse direction over a printed web printed in the printing press, the matrix camera being adapted to capture an excerpt of the printed image in synchronism with a repeat of the printed image during a print run,
an inspection system for a complete inspection of the printed image, said inspection system including a line camera that extends over the entire width of the web and adapted to capture a complete image of the printed web and storing the same in digital form which is linked with positional information indicating a location of a respective image area in a longitudinal direction of the web,
an integrated control desk for the web monitoring system and the inspection system, and
a data processing system adapted to automatically detect errors in the image printed onto the web by analyzing the image captured with the line camera and to display the errors visually on a screen of the control desk, the data processing system being adapted to automatically adjust the matrix camera onto a position for a closer inspection of an error when such error has been detected in an automatic error detection process.
5. The apparatus according to claim 4 , wherein the control desk has a touch screen for selectively displaying at least one of:
an image delivered by the matrix camera and
an image delivered by the line camera
and for inputting operating instructions.
6. The apparatus according to claim 4 , wherein the matrix camera has an optical zoom function.
