Make an impression (5)
I believe this clue is a double definition.
'make' is the first definition.
(printing is a kind of making)
'impression' is the second definition.
(impression created by a printer)
'an' is the link.
(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" .)
'make an impression' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for register that I've seen before include "(Put one's name down on) list" , "Class roll" , "New arrival at hotel will" , "Official record of names etc." , "Check in - catalogue" .)
