Parts of answers have come through private mail. I'm told that there should be support for the HCT target in future releases of i1Profiler, which I believe is a good move from X-Rite. On the other hand, what looked to me almost too good to be true has proven to be false hope. I could get hold of an old IT8 target to try the scanner profiling part of the software. It loads the image and file, but stops at the data processing step with message "can't find the appropriate dongle". The basic Display Pro package does not allow for scanner profiling, an expensive measuring device must be connected. The route for me is a BasiCColor upgrade, or keep the old gear running, which I'll probably do for a while. But it's good to know that the HCT has future. Many thanks to all who provided parts of information. Regards Paul Schilliger
