Be aware that the Munki does not activate/measure the OBA effect of papers that have OBAs aboard. Your eyes will with the display light conditions you neutralise the prints for. The 810 does not measure UV light either. Whether that is achieved by a UV cut filter on both lamp and sensor I do not know. With both, the tone range reading should be similar to that of the Munki without the color information of course. -- Met vriendelijke groet, Ernst Dinkla http://www.pigment-print.com/spectralplots/spectrumviz_1.htm December 2012: 500+ inkjet media paper white spectral plots.
