Polaroid Packfilm Emulsion Lift Permanence
I am working on a project right now, and I am thinking as of now that it will involve emulsion transfers (or lifts) onto fabric. I am unsure if an emulsion transfer (peel after 20 seconds, and place the negative onto the fabric) or an emulsion lift (boil the dry print to lift the emulsion) is the best way to go.
My questions revolve around the Fuji films, since they're all that are available now. Does anyone have experience with doing either of these processes with Fuji films? I've seen videos that prove they are possible, but I am unsure how it differs from the Polaroid 669 process (other than requiring a darkroom in the case of emulsion transfers).
How permanent are the transfers? If I transfer the emulsion and developing agents onto a piece of silk, for example, will it peel away and flake off within a certain period of time? This will be for a sculpture (I don't want to mess with Liquid light; Dektol will stain the fabric, and iron on transfer paper looks terrible), so it won't be washed or dryed. I will do all dye work and embroidery before I do the transfer so the fabric moves as little as possible before I do the emulsion lifts.
I have examples of emulsion lifts onto watercolor paper that have survived for about 3 years now. They are in frames and I bet they'll last as long as any other print. I have never worked with emulsion transfers though, either in 669 or Fuji.
Which way would you recommend going, an emulsion lift or emulsion transfer? And is there any word on permanence; is an overcoat of Mod Podge or some other medium necessary?
