For those not familiar with the process, it was historically used to put text on the spines of books, when it was called gold tooling.
I have a small block stamper, and the foil is something like a mylar film, coated with an anodised layer of aluminium, and a heat/pressure sensitive adhesive layer.
Press the hot platten, carrying a flat relief design in metal, onto the foil laying on the object below, and the adhesive(shellac?) transfers the coating from the mylar to the object.
A good, cheap and reliable system for small areas.
However, I need to print metallic designs over a large area, typically 12" x 24".
Is it possible to either cut the foil, ie the mylar carrier, or ‘burn off’ the metallised layer, which was laid down by an evaporative process.
