Masthead title (6)
I believe the answer is:
editor
'masthead title' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for editor that I've seen before include "Someone in the rag trade" , "One who revises another's writing" , "Newsman" , "One working on paper" , "Ted or I could bring out a newspaper" .)
