De-install and re-install from the DVD. Try a different i1 spectro, check the calibration of the Epson 3800 with the colorbase utility, nozzle checks, printed more charts on both gloss and matte paper and allowed them to dry fully.
Still the charts from the 3800 won’t be read with Profiler; “Invalid measurement: Reference colors do not match measure values. Please check you are scanning row (x) and try again.”
Then I printed out some charts from an Epson 1800. They read and profiled OK. The optimisation procedure also worked (not sure what, if any, improvement I can see yet, but the optimised profile has a 3.8% smaller gamut volume than the original according to Gamutvision )
So this is starting to look like the software isn’t able to accept the dark unprofiled output from the 3800. From the thousands of targets sheets I’ve seen in the past few years I know my 3800 is pretty representative of the K3 inkset ‘s output, so this could be a real problem for a lot of users.
If I could find a way of loading reference and measurement files from PMP into profiler I could probably investigate this further, but I can’t find any way to do this yet. Anyone know what needs to be done to accomplish this ? An X-Rite rep told me it was possible.
