Metallic inks are available in three reflective colors: gold, silver or bronze plus a new array of pastel colors. Caution should be exercised when specifying metallic inks for small, finite type, as the metallic particles used in these inks are not as finely ground as color pigments. A rich surface gloss can be achieved by a second pass through the press to “burnish” the surface of the ink. Burnishing forces the metallic particles to flatten and reflect more light. It can also reveal extremely subtle details within the engraved image.
