Abstract

A control station for a printing press, includes at least one true color monitor for displaying at least one soft proof serving as a color reference for printed copies printed during the printing process, and at least one standard light source for at least partial illuminating the control station to allow visual comparison, independent of room lighting, of a printed copy with the soft proof serving as the color reference. The luminosity produced by the at least one standard light source is variable, so that the luminosity produced by the at least one standard light source can be adjusted to match a brightness achievable on the true color monitor to match a contrast achievable on the true color monitor during the display of the soft proof.

Claims

1. A control station for a printing press comprising:

at least one true color monitor displaying at least one soft proof serving as a color reference for printed copies printed during the printing process;

at least one standard light source radiating standard light at least partial illuminating the control station to allow visual comparison, independent of room lighting, of a printed copy with the soft proof serving as the color reference;

wherein the luminosity produced by the at least one standard light source is variable, so that the luminosity produced by the at least one standard light source is adjustable to match a brightness achievable on the true color monitor and to match a contrast achievable on the true color monitor during the display of the soft proof; and

an open-loop or closed-loop control unit for storing values of the luminosity produced by the standard light source used to influence the incidence of standard light on the true color monitor, the setting of a blind or shade used to influence the incidence of standard light on the true color monitor, or the setting of a device used to influence the incidence of stray light on the control station, and for manually or automatically controlling the luminosity values and the settings, wherein predefined settings and luminosity values are accessed from the open-loop or closed-loop control unit.

2. The control station according to claim 1, wherein the luminosity of each of the at least one standard light source is variable.

3. The control station according to claim 1, wherein the at least one standard light source comprises a plurality of additional at least one standard light sources and the number of standard light sources which can be turned on is variable.

4. The control station according to claim 1, further comprising at least one blind or shade disposed between the at least one standard light source and the true color monitor to adjust the incidence of the at least standard light on the true color monitor.

5. The control station according to claim 1, further comprising at least one device shielding at least the true color monitor from the incidence of stray light.

6. The control station according to claim 5, wherein the at least one device is moved by an electric motor to shield the entire control station from the incidence of stray light.

7. The control station according to claim 1, further comprising at least one standard light-absorbing device which is assigned to the standard light source, and is selectively disposed in front of the at least one standard light source to change the luminosity produced by the at least one standard light source.

8. A control station for a printing press comprising:

at least one true color monitor displaying at least one soft proof serving as a color reference for printed copies printed during the printing process;

at least one standard light source radiating standard light at least partial illuminating the control station to allow visual comparison, independent of room lighting, of a printed copy with the soft proof serving as the color reference;

wherein the luminosity produced by the at least one standard light source is variable, so that the luminosity produced by the at least one standard light source is adjustable to match a brightness achievable on the true color monitor and to match a contrast achievable on the true color monitor during the display of the soft proof; and

at least one standard light-absorbing device which is assigned to the standard light source, and is selectively disposed in front of the at least one standard light source to change the luminosity produced by the at least one standard light source.
