Most quality surface plates have mounting pads or locations marked on the bottom. Don't know about Enco. If there are no markings, in a plate that small and for home shop use you could get by with something like a carpet pad underneath. You'll also want to build a cover for it.

Surface plates are ideally mounted on three points located underneath in accordance with FecSpec umpty-ump as in Glenn's rewsponse. Smaller surface plates will work just as well sitting on a piece of carpet. It will move a little but not enough to mess up anything sensitive.

Anyone wishing to mount a surface plate properly should follow the spec. If you wish to level it for convenience in set-up of stuff on jacks, build support jacks into the stand.You'd be well advised to locate stops in near contact with he plate corners on the end having a single support point. This keeps the plate from tipping if you happen to load it really - REALLY - assymetrically.
