Hello,
The newest model is the Craft ROBO Pro and it is lighter in color. The older model is the Craft ROBO Pro II (I know it's confusing) which is dark in color. The new Craft ROBO Pro is the same machine as the Graphtec CE5000-60 just smaller and without the floor stand. The Craft ROBO Pro can handle from 15" -19" wide materials and has a maximum cutting width of 14.6" which is plenty for most T-shirt applications.
Regarding the original question and the registration marks in Illustrator, did you install the plug-in for Illustrator? We normally use the plug-in for Corel Draw and it added a "Cut/Plot" and "Registration Marks" menu items under the application launcher. We don't have Illustrator yet so I can't give you more specifics to that program. The plug-in for Corel Draw is very easy to use and I prefer it to the stand-alone Robo Master software that comes with the Craft Robos. Lots of great features including sizing, mirroring, welding, auto-weed box, multiple copies, etc...
In my opinion the Craft ROBO Pro is a very impressive machine and tops my list for features, power and value in a compact machine.
Hope that helps,
Dave Lawrence
