No ink is on spoilt paper (9)

Ross

I believe the answer is:

onionskin

'paper' is the definition.
(type of thin paper)

'no ink is on spoilt' is the wordplay.
'spoilt' is an anagram indicator.
'no'+'ink'+'is'+'on'='noinkison'
'noinkison' anagrammed gives 'ONIONSKIN'.

(Another definition for onionskin that I've seen is " Very thin variety of paper".)

I've seen this clue in The Times.
