Lets be fair. For a user with an EyeOne Pro, the upgrade to an i0 isn’t as big a deal as an iSis and you have the ability to measure very thick and odd substrate, along with the benefits of a handheld Spectrophotometer. If you have an EyeOne Pro, want to automate the process, get an i0. If you have nothing, an iSis is a better solution for just measuring a lot of patches. But you want to profile a projector, spot measure etc? You’re SOL. So different products, and solutions. I’ve received targets that were for whatever reason, targets printed for an iSis that were incorrectly scaled. The iSis acts like a door stop! Pop that target on an i0, setup a spot measurement with the arm, walk away, you’ve got your measured data.
