Metallic inks are special printing inks that contain metallic particles, giving them a shiny, reflective appearance. These inks are often used in various applications, such as packaging, labels, and art prints, to create eye-catching designs. The metallic effect can enhance the visual appeal of printed materials, making them stand out. These inks can be made from different materials, including aluminum or copper flakes, and are available in various colors. They can be used in both offset printing and digital printing processes. However, metallic inks may require specific printing techniques to achieve the desired finish and durability.
