Monitoring device for densitometrically evaluating printed sheets with a printed print-monitoring strip includes holding means, a plurality of first densitometers for exclusively measuring full-tone density carried by the holding means at a selective spacing from one another so as to define respective gaps between the first densitometers, and a plurality of second densitometers for measuring at least one tone density value selected from a range of screen and full tone values, the second densitometers being receivable, respectively, in the gaps between the first densitometers and being connectible to a device for mathematically correlating the values measured by the second densitometers with quality-assessing parameters. |
