Unwrap texture for printing 2d image (baked image)

Hi everyone!
I’m new in this forum, i hope to find the solution of my problem here…

I need to print a label to stick on a bottle. I prepared the label in illustrator, then i putted the image on the 3d bottle. Now i need to do a sort reversing engineering stuff, exporting an image that i can print 2d, cutted and then stick it on a real bottle.

Question:
DO i put the image on the bottle directly or shoud i create a “label” and shrinkwrap it on the bottle??

Unfourtunately, being a new user i can not embed images…

Thank you guys!
