http://www.aardenburg-imaging.com/news.18.html http://www.pigment-print.com/spectralplots/spectrumviz_1.htm There are more aspects to the use of OBAs that have to be considered next to the degradation of the OBA dyes in time. Papers with OBA tend to have less color constancy in changing light conditions (incorrectly called "metamerism"). Spectrometers used for profile creation often are UV-cut so do not create an OBA effect in the measurements and the profiling software usually compensates that in one way or another. In practice that seems to work but is a somewhat arbitrary method. To sum it up; there is more precision/reliability in a profile made with a UV enabled spectrometer of an OBA free paper than in one made with a UV cut spectrometer on an OBA paper. Yet the last conditions are more often encountered. -- Met vriendelijke groet, Ernst Dinkla http://www.pigment-print.com/spectralplots/spectrumviz_1.htm December 2012: 500+ inkjet media paper white spectral plots.
