Decorated glass having a printed ink layer
Embodiments of a decorated glass are provided. The decorated glass includes a transparent substrate having a first major surface and a second major surface. The second major surface is opposite the first major surface. The decorated glass also includes a black ink layer disposed on the second major surface in a display region. The black ink layer has a transmission coefficient of between 0.2 and 0.85 with respect to incident light having a wavelength of 400 nm to 700 nm. The decorated glass has 2% or less of sparkle when measured from the first major surface via pixel power deviation reference (PPDr).
