Re: Optical - servo alignment or "registration"

For a number of purposes (eg. registration of printing) it's useful to

(perhaps with previous impressions already having been made) with the
printing screen, stencil or plates.

What's available off the shelf for that sort of thing? I must not be
using the correct search terms- I'm not finding much. This should be a
fairly standard building block for motion control systems.


This company should be able to help since they have built small positioner tables almost since I was a kid:
