Method for color measurement in printing presses |
| 摘要 |
A color measurement on printed materials produced by a printing press is performed by at least a first color measuring device installed in the printing press and at least a second color measuring device. A signal is output by the first color measuring device in the printing press when the measured color values registered on the printing materials are located within a predefined tolerance limit for a predefined period and that, after the signal has been output, a color measurement on one of the printed materials thus produced is performed with the second color measuring device. |

1. A method for color measurement on printed materials produced by a printing press, which comprises:
measuring color values on the printed materials with at least one first color measuring device installed in the printing press; determining that the printing press has reached a stable production state when measured color values registered on the printed materials are located within a predefined tolerance range for a predefined period; after the printing press has reached the stable production state, outputting a signal from the first color measuring device on a monitor; and after the signal has been output from the first color measuring device on the monitor, performing a color measurement on one of the printed materials produced during the reached stable production state with at least one second color measuring device. |
