flat plate is an engraved process. You will feel a roughness to the design when you rub a fingernail across it. Also, you will usually see a partial design transference of the stamp on the back.
Offset printing is smooth when you run your finger nail across the design. The back of the stamp will not show any ink transference.

Another technique is to place a piece of aluminum foil over the stamp and rub the foil. no need to press very hard. An engraved stamp will leave an impression in the foil.

My way is to use the back tip of the nail moved gently as Michael says. You can also angle stamp to the light and it will show up raised like 3D.

When I mentioned that procedure some time ago to a fellow member,
he stated somewhat emphatically that he never touches his stamps
with his fingers. Unlike Victoria, I was amused.

I am looking for advise on how to tell the difference between off-set printing and flat plate printing on the 1908-1922 Franklin/Washington definitives. Thank you for your help. Mike
