Lasal Exhibition Luster 300... Lasal Exhibition Luster is a true heavyweight, archival exhibition-quality luster paper, designed for use with all inkjet printers. The paper is coated with the latest fourth-generation technology to produce an extra-wide color gamut never before seen in a luster paper. Named after the LaSal mountains, whose snowy peaks tower above Moab keeping watch on the canyon lands below, Lasal Exhibition Luster remains true to its namesake, incorporating many of the elements found in the surrounding Moab environment: pure crispy whites and deep, luscious colors. Basis weight: 300 gsm, 11 mil.
