coat your image with three coats of matt medium allowing image to dry thoroughly between coats (pref. overnight).
Wet thoroughly, and rub off (using fingers) the paper of the image - it balls up and takes quite a while. Keep wetting as you go. Be gentle, you don't want to tear the image.
When all paper is off, put matt medium where the image will be on the canvas and lay carefully over. You only get one chance so take it slowly and carefully.
Practise the technique on something else first.
The Acrylic Revolution Book says to use gloss medium, but I successfully used matt.
Good luck (and show us your results)
