Navigator UHD - Ultra High Definition. The results are absolutely stunning: fast drying times for inks, ultra-vivid colors, and deeper blacks. The Gamut color area, one of the most common laboratory measurements of color definition, shows that the new Navigator UHD improves print quality by 40%. Developed by the Research and Development department of Navigator, the new formula enhances ink absorption, keeping the color pigment near the surface of the sheet intact. Combined with the finest raw material - Eucalyptus Globulus - which allows for a finished product with excellent whiteness and superior smoothness, the new UHD formula represents a step forward in printing definition standards.
