Lumachrome
Face-mounted to TruLife acrylic
A layered transparency print, face-mounted to anti-reflective acrylic. The image is printed on clear film over a white reflective base, so light passes through the emulsion twice — inbound and outbound — before it reaches the eye.
The image is printed at 1200 ppi and 16-bit onto a transparency layer infused with iridium particles, which is then laid over a white polyester base. Incident light passes through the image layer, reflects off the white substrate, and passes through the image layer a second time on the way out. That double transit raises effective optical density and color saturation compared with a single-pass reflective print, where light interacts with the colorant only once. It is the same principle that makes a transparency on a lightbox outperform the same frame on paper.
Face-mounting bonds the print directly to the back of the acrylic with an optically clear, pH-neutral silicone adhesive. Removing the air gap eliminates two refractive-index boundaries that conventional glazing introduces, along with the secondary reflections and slight parallax between glazing and image that come with them.
The glazing is TruLife, an acrylic with a single-sided anti-reflective hard coat specified for face-mount applications. Mounted, its surface reflectance measures under 1.5%, against approximately 4% for uncoated acrylic — the Fresnel reflection of a bare air-to-acrylic interface — with total transmission above 98%. It blocks up to 99% of UV between 300 and 380 nm, and the coating is abrasion-resistant and anti-static. The assembly is backed rigid against bowing and finished with diamond-milled satin edges. The process carries a manufacturer rating in excess of 120 years.
