When you separate the page, the logo will come out on its own plate. Just remember to define the colors as spot, and they'll come out on their own plates. A less common approach to using spot colors involves printing a specialty ink underneath the process colors. This is often referred to as bumping the color, and the necessary extra plates are referred to as bump plates. While any color beyond the ubiquitous CMYK can be considered a specialty ink and thus a spot color, some inks are formulated differently from other spot colors and require more care when planning a job.
Metallic inks contain tiny flakes of metal that reflect light.
Varying the metallic composition of the flakes creates color shades. Because the flakes lie flat and leaf, or join together, on smooth surfaces, they produce a higher luster on coated papers. Tinted metallics are created by mixing spot and process colors with pure metallic inks. The mix reduces the metal flake concentration, thus reducing reflectivity. The Pantone Metallic Color Guide offers 204 metallics and premixed metallic tints.
