Hi,
I've just done an emulsion lift using Polaroid 664 B&W film, which went without any problems (first time I've done it), but I also knew that the B&W emulsion doesn't stick too well to the receptor (watercolour paper). Or rather, not as well as 669.
So, my question is, how can I make sure that the emulsion sticks properly to the paper? Is it a matter of using a roller really hard? Do I use a shellac spray to makek it stick? Or something else?
The majority of the emulsion is actually OK, but a couple of the edges came 'unstuck' from the paper.
Thanks,
David.
