Pressure put on a newspaper concerning model (7)
I believe the answer is:
paragon
'model' is the definition.
(paragon is a kind of model)
'pressure put on a newspaper concerning' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'put on' says to put letters next to each other.
'newspaper' becomes 'rag' (rag is a kind of newspaper**).
'concerning' becomes 'on'.
'p'+'a'+'rag'+'on'='PARAGON'
(Other definitions for paragon that I've seen before include "A model as of virtue" , "Perfect embodiment of a concept" , "Flawless model" , "An ideal" , "Perfect example of a quality" .)
