Make an impression (5)
I believe this clue is a double definition.
'make' is the first definition.
(I know that print is a kind of make)
'an impression' is the second definition.
(impression created by a printer)
(Other definitions for print that I've seen before include "Produce a paper copy" , "Non-joined-up writing" , "Copy of a film" , "Reproduction picture" , "Publish; patterned fabric" .)
'make an impression?' is the definition.
(to etch is to make an impression in something)
This is all the clue.
(Other definitions for etch that I've seen before include "Delineate" , "Cut into a block used for printing" , "Carve into surface, impress deeply" , "Make deep lines" , "Cut design onto metal using acid" .)
