Article deals with tip. Make a few copies (10)

I believe the answer is:

triplicate

I'm a little stuck... Click here to teach me more about this clue!

'make a few copies' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'article deals with tip' is the wordplay.
'deals with' indicates an anagram (I've seen 'dealt' mean this).
'article' with its letters anagrammed with 'tip' makes 'TRIPLICATE'.

Can you help me to learn more?

(Other definitions for triplicate that I've seen before include "Threefold" , "State of having three identical copies" .)

I've seen this clue in the Sydney Morning Herald.
