Misprints (6)
I believe the answer is:
errata
'misprints' is the definition.
('erratum' can be a synonym of 'misprint')
This is all the clue.
(Other definitions for errata that I've seen before include "Mistakes in printed matter" , "List of text corrections to be made in a publication" , "Noted mistakes" , "List of errors" , "Printing corrections" .)
