    Abstract: Für die Farbmessung von auf einem Aufheller enthaltenden Substrat gedruckten Proben wird in einer ersten Messung ein roher spektralen Reflexionsfaktor der Probe unter Beleuchtung der Probe mit Licht ohne UV-Anteil gemessen. In einer zweiten Messung wird unter Beleuchtung der Probe nur mit UV-Licht ein Fluoreszenzspektrum der Probe gemessen. Das gemessene Fluoreszenzspektrum wird durch Gewichtung mit spektral abhängigen Korrekturfaktoren in ein korrigiertes Fluoreszenzspektrum umgerechnet und schliesslich werden der gemessene rohe spektralen Reflexionsfaktor und das korrigierte Fluoreszenzspektrum zu einem korrigierten spektralen Reflexionsfaktor addiert, aus welchem dann die Farbe der Probe charakterisierende Werte berechnet werden. Die spektralen Korrekturfaktoren werden bei der Geräteherstellung für ein bestimmtes Set von Lichtarten bestimmt und im Gerät gespeichert.

    Abstract: An LED-based color measurement instrument including an illumination system and a sensing system. The illumination system includes modulated LEDs and a temperature control system for regulating the temperature of the LEDs, thereby improving the consistency of their performance. The sensing system includes a photodiode, a transimpedance amplifier, and an integrator in the first stage to cancel the effect of ambient light on the output of the first stage. The sensing system also includes a lens system for imaging a target area of the target sample onto the photo sensor in a manner so that the product of the target area times the solid angle captured by the lens system is generally uniform over a selected range of distances, thereby reducing the positional sensitivity of the instrument with respect to the target sample.

    Abstract: A system for automatically re-calibrating a spectrophotometer which is mounted on a color printer for measuring colored test patches printed on test sheets moving thereby, and sequentially illuminated with different color illumination sources. Re-calibration is provided by illuminating, with the same sequenced illumination sources, during a time coinciding with an adjacent gap between the printed sheets, a stationary calibration test patch. This re-calibration timing may be provided by the existing sheets positions tracking control system of the printer.
