美国采购需求：热烫金箔、冷烫金箔、数码烫金箔、颜料烫金箔和特种烫金箔

I'm in the market for high-quality gold foil options, both genuine and imitation, suitable for stamping on vegetable-tanned bookbinding leathers. The performance should be optimal for imprinting names, titles, or various graphics. Additionally, I'm interested in gold foil for stamping on different types of cloth, including thin and thick starch-impregnated materials, as well as heavier whole cloth types. Is there a special "pre-stamping" product available that facilitates the stamping process on open-weave cloth?
