Theyre fade-resistant. Pigment ink doesnt soak into paper like a dye-based ink instead, it dries on top. That means the ink takes a little longer to dry on regular paperbut the color will be more vivid. It also means that pigment ink will not dry on glossy paper. If you want to stamp pigment ink on glossy paper, you must heat-set it with an embossing gun for it to dry. Because pigment ink stays wet for so long, its perfect for Heat Embossing!
