Export lines only of a rig

Does anybody knows how to export all lines of a rig into a single PNG without superimposing the lines?, it should look like the rig with lines and color, but without color, my client wants one png sequence for line and one for color, thank you for any tip or suggestions

Will you need the content the lines surround/outline to be transparent or opaque? Meaning, you could have a circle and see everything behind the circle by looking inside and outside the circle or you could have it so the inside of the circle is blank.

Thank you for the reply, but I found the solution to what I need, was simple, I group whole rig, and outside the group I connected the “Line Art” Node, when I export the PNG I have all the beautiful lines of the character without any fills.
