I got some of this newer stuff to try out, it's pretty nice. Below you will see a scan of the standard silver and the hub-printable types, and a photo of a print job. I recommend 24x117mm print size, although they will take 23x118. The print surface is slightly larger on the outside and smaller on the inside than the reflective coating. They have added some kind of reflective coating over most of the hub area, although you can still see the "rings". The effect is that if you are printing a darker image, the hub area is barely visable.
Also noted that the new hub-printable has a "brighter" print finish, so that colors are brighter. The photo below accentuates the difference, it's not that much different. But is is very nice.
