Subject: [CR]Stress risers and Pantographing

I have been told that on the prototype C Record cranks there was an engraved or Pantographed logo that left stress risers in the arm and crank failures resulted so the logo was subsequently moved and laser etching used instead. My question is...Does Pantographing of parts typically leave such risers and why or why not? I certainly have not heard of any great amount of failures among Pantographed parts.
