The “MP” in MUTOH MP31 ink stands for Multi-Purpose, and MP 31 ink can print directly on awide variety of materials, including acrylic, PET, metal and synthetic leather, as well as paper.
Compared to UV ink, it is less uneven and smoother, and produces a natural finish that brings out
the texture of the material.

gamut and broadens the range of color expression. These inks produce more vibrant and beautiful
color expression including vivid orange and green, and deep blue.
