Not an upright type (6)

I believe the answer is:

italic

'not an upright type' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for italic that I've seen before include "Principally it" , "Relating to slanting handwriting or type" , "leaning over" , "Type of script" , "from Rome?" .)

I've seen this clue in The Globe and Mail.
