Ink Matte Control on every reflective surface
Print an ink film over a reflective surface and the reflection beneath gets dulled — the ink scatters incoming light before it reaches the substrate and again on the way back to the eye. V3R now models this directly across every substrate type that has any specular character: foil, rainbow holographic, brushed metal, glitter, plastic, clear film, and pearlescent papers. Each ink layer's coverage feeds into a live mask that locally reduces the substrate's specular response, giving you the soft, partly-mirrored look real ink-on-reflective-stock has rather than the unrealistically pristine reflection of earlier builds.
The physics is split correctly between ink types. Translucent inks — CMYK, fluorescent neons, ECG, generic spots, and the ColorLogic CMYK pass — dull the substrate in proportion to how much ink film sits on the surface, scaled by their opacity slider so a single-pass run dulls less than a double-pass. Opaque-at-100% inks — white, metallic, and the ColorLogic Silver / White / Custom Metallic effects — only contribute when their opacity is reduced, since at full opacity they completely hide the substrate and there's nothing left to dull.
A single Ink Matte Control slider sits in the Substrate Controls panel whenever a substrate with specular character is active. The default of 0.4 is calibrated to look natural across most jobs; pull it higher for a heavier, more matte ink character, lower for a glossier finish. Each substrate type remembers its own value via the existing Save as Default / Reset to Default / Factory Reset buttons, so you can dial in foil's reflectivity to taste without affecting how brushed metal, plastic, or clear film look.
Rainbow holographic substrates get a bonus: the slider also tames the holographic shimmer where ink covers — the diffraction effect needs an unobstructed surface to work, and now the rainbow correctly recedes beneath ink layers rather than fighting through them. Plain (non-pearlescent) papers are deliberately excluded since there's no sharp reflection to dull on a matte paper surface — ink-on-paper is just print, and shouldn't change with this slider.
