Which printing technique is ink applied to a design cut into an metal plate which is then processed onto paper to transfer the image

Intaglio is the answer you're looking for i believe :)

Hope this helps!

your word would be isle.

isle is an island or peninsula especially a small one.

if you add the letter "a" you get aisle, which is a passage between 2 rows of something like chairs, shelves, or something else.
