Abstract

Die Erfindung betrifft ein Verfahren zur Messung der Farbgebung im Rollen-Druck, dadurch gekennzeichnet, dass ein Messkopf oder mehrere Messköpfe eine integrierende Messung des von einer bedruckten Materialbahn remittierten Lichts in Laufrichtung der Materialbahn ausführt oder ausführen, sowie eine Vorrichtung zur Messung der Farbgebung im Rollen-Druck, vorzugsweise zur Durchführung des Messverfahrens nach einem der vorhergehenden Ansprüche, die Vorrichtung umfassend:
a) wenigstens ein Sensorelement zur Aufnahme von Licht, das von einer laufenden, bedruckten Materialbahn remittiert wird,
b) eine Summier- oder Integriereinrichtung, die mit dem wenigstens ein Sensorelement verbunden ist, um die Intensität des aufgenommenen Lichts zu ermitteln,
c) und eine Steuerung, die für eine in Laufrichtung der Bahn summierende oder integrierende Intensitätsmessung des remittierten Lichts die Zeitdauer der Lichtaufnahme und/oder die Zeitdauer der Summierung oder Integration mittels der Summier- oder Integriereinrichtung vorgibt.

The invention relates to a method for measuring the coloring in the roll printing, characterized in that one or more measuring heads performs an integrating measurement of remitted from a printed material web light in the running direction of the web, or a device for measuring the coloring in rolls Printing, preferably for carrying out the measuring method according to one of the preceding claims, the device comprising:
a) at least one sensor element for receiving light which is remitted from a running, printed material web,
b) summing or integrating means connected to the at least one sensor element to determine the intensity of the received light,
c) and a controller which predetermines the duration of the light absorption and / or the time duration of the summation or integration by means of the summing or integrating device for an intensity measurement of the remitted light summing or integrating in the running direction of the web.
