Print something penetratively (7)
I believe the answer is:
stencil
'print' is the definition.
(I know that stencil is a more specific form of the action print)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for stencil that I've seen before include "Text template" , "Cut-out for painting patterns or shapes" , "Method of decorating" , "Create design" , "Cut-out for applying ink" .)
