I first printed my photo then I put it through my copier which is an ordinary 3 in one printer
now whether it's a coincidence or what, it didn't  work from a printed one but has from the copier ones,
 and also my nail varnish remover I've just noticed
is acetone free, just done some more of the same photo and it's worked
Have fun Nena x
Make sure you use a well ventilated room because it 's over powering   (OH prefers to be outside in the cold)
