For those in a position to compile Argyll from source, and in possession of either a Spyder 3 or ColorMunki, the current development snapshot should allow you to test the upcoming Argyll release with your instruments. <http://www.argyllcms.com/Argyll_dev_src.zip>. Note that this is not a complete release, and that a number of areas aren't functioning normally (gamut mapping and targen in particular are in in a state of flux), but the usual instrument access utilities (spotread, dispread, chartread) should be functional, including printtarg. cheers, Graeme Gill.
