Nope. Or the stuff from Profile City...

With Eye-One Share yes but that software exports a file that is proprietary
so you can't import that data into another package if that's what you mean
(like you can with SpectroCam). The Spectral data is purposely "locked" for
obvious reasons. Now the software (Eye-One share) does produce the LAB
values of patches you measure so I guess if you were really patient you
could write down all the values for all the patches you measure, type them
into a text editor (with correct formatting) and import into a profiling
application that accepts this kind of data. Not my idea of a fun afternoon!

I have no scientific means of figuring out how accurate the Eye-One is but
can say that I've made profiles that are of excellent quality. It's not yet
possible to do an apple to apple test since there is no support for the
Eye-One in ProfileMaker Pro or DTP-41 support in the Eye-One software. But I
did make profiles using both and found the resulting prints were very, very
close indeed. But while the Eye-One software is said to share the basic
color science behind ProfileMaker Pro, I can't say how close the two
products really are. Bottom line is the Eye-One hardware and software has
produced very good RGB and CMYK output profiles.
