V3R v1.3 — What's New
Release Notes · v1.3

The physics of finishing, refined.

The biggest substrate-physics release V3R has shipped. New Ink Matte Control simulates the way translucent inks dull every substrate that reflects light — fluorescents, neons, ECG inks, CMYK, ColorLogic effects, and white/metallic spot inks all now interact correctly with foil, rainbow holographic, brushed metal, glitter, plastic, and clear film bases. Press-pass density sliders for every neon and ECG ink. A complete matte lamination physics rebuild. Spot-UV burn-back. Multi-page companion files. And a critical GPU compatibility fix for Mac users who'd silently been hitting a black-page bug with Sculptured Varnish.

Substrate physics & ink interaction

Inks & surfaces, talking properly
New substrate physics

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.

How: Substrate Controls → enable any reflective substrate (Foil Substrate, Rainbow Holographic Foil, Brushed Metal, Glitter, Plastic, or Clear Material) → adjust the Ink Matte Control slider that appears.
New ink control

Press-pass opacity for neon & ECG inks

Fluorescent and ECG inks now carry their own opacity slider, the same as metallics and white. The default of 100% reflects the recommended single-pass density values supplied directly by the press manufacturers — Ricoh, Sharp, and the rest — so jobs imported with default settings render exactly to spec. Below 100% simulates a thinner ink film, useful for previewing how a single-pass run will look against a job that was costed for two passes, or vice-versa.

Opacity also feeds into the new Ink Matte Control: less ink film on a reflective substrate dulls the reflection less, so the slider gives you a single intuitive control for both visual ink density and substrate interaction.

How: Per-layer panel for any neon or ECG ink → Opacity slider beneath the colour picker.

Lamination & burn-back

A new chapter for matte
New finishing physics

Matte lamination, properly behaved

Matte lamination has been rebuilt from the surface up. The old model lifted blacks toward grey when the gloss slider sat anywhere below maximum — a side-effect of an over-eager environmental haze that wasn't grounded in how matte film actually scatters light. That haze is gone, and what replaces it is a more honest dimming of sharp reflections that leaves your dark areas dark.

Three controls now do what they say. Matte ↔ Gloss moves cleanly between satin and full gloss. Matte Texture adds the subtle micro-roughness of a textured matte film. Matte Veil is the optional desaturating veil for the heaviest matte stocks. Every slider has a tooltip explaining its role, and the factory default of full gloss means enabling lamination doesn't surprise anyone.

How: Substrate Controls → Lamination → adjust the three named sliders. Hover for tooltips.
New finishing effect

Spot-UV burn-back

Real spot UV applied over a matte-laminated surface locally re-glosses the area beneath — the varnish "burns back" the matte film and reveals a sharp, mirrored finish exactly where the spot is printed. V3R now simulates this faithfully. Drop a varnish layer over a matte-laminated job and the matte effect cancels itself underneath the varnish geometry, with a clean falloff at the edges.

Each varnish layer carries its own Override matte (burn back) toggle, on by default. Turn it off for varnishes that should sit on top of the matte without burning through — a sculptured varnish over matte film, for example, where the goal is texture rather than re-glossing.

How: Per-varnish-layer panel → Override matte (burn back) checkbox.

Workflow improvements

3 quality-of-life additions
Mapping manager

Dedicated foil colours in the mapping dropdown

Mapping a custom-named spot to a known foil colour used to mean two steps: pick generic Foil from the dropdown, then open the layer panel and choose Gold (or Silver, or Red) from the foil colour picker. The Layer Mapping Manager now offers eight dedicated foil presets directly — Silver Foil, Gold Foil, Red Foil, Green Foil, Blue Foil, Pink Foil, Purple Foil, Bronze Foil — alongside the existing Holographic option.

Pick the colour you want and the layer arrives in the sidebar already named and configured. The generic Foil (Custom Colour) option remains for when a customer has something genuinely off-spec.

How: Layer Mapping Manager → effect dropdown → select any of the named foil colours.
Add Layer

Pick a page from a multi-page companion file

Versioned and variable Duplo or sleeking files often arrive as a single multi-page PDF — page 1's varnish layout, page 2's foil layout, and so on. Until now, Add Layer would silently pull page 1 of the companion regardless of which host page you were viewing. It now opens a thumbnail picker showing every page of the companion file with a low-res grayscale preview, separation count, and a clear selection state.

Single-page PDFs skip the picker entirely and behave exactly as before. Thumbnails are cached per session, so re-importing the same companion onto a different host page is instant. Cancel and Escape both bail out cleanly with no side-effects.

How: + Add Layer → choose a multi-page PDF → pick a page from the grid → continue with the existing mapping flow.
Mapping manager

Empty channels default to Ignore

Every PDF arrives with all four CMYK plates whether they hold artwork or not. A black-only Duplo file has perfectly empty Cyan, Magenta, and Yellow plates — and clicking through three "Ignore" selections every time was friction nobody needed. The mapping manager now samples each separation as it loads, and any plate with under 0.05% ink coverage is flagged with a grey ⊘ Empty badge and pre-set to Ignore.

The threshold is generous enough to ignore reg marks and crop artefacts, but anything resembling actual artwork — even sparse work — still appears as a populated layer. The dropdown stays editable, so if you do want to keep an empty layer for some unusual reason, that choice is still yours.

How: Automatic on every Layer Mapping Manager open. Look for the ⊘ Empty badge.

Substrate ink-matte

Toggling ink layers off no longer leaves ghost matte on the foil

Hiding an ink layer used to leave its dim contribution baked into the substrate's foil reflection until another layer was toggled. The ink-layer checkbox handler is now centralised through the same path that drives the holographic-film coverage mask and varnish refresh, so every visibility change — including bulk Show All / Hide All — rebuilds the foil ink-matte mask cleanly. The ghost is gone.

Neon & ECG opacity

Opacity slider now visibly fades the ink, not just its alpha

The neon/ECG/CMYK ink shader uses multiply blending, which means writing the slider value to the alpha channel had no visible effect — a bug that had been hiding in V3R since these layer types were first added. Opacity is now applied as a mix toward white in the colour pipeline, so the slider correctly fades each ink under multiply blending exactly as the press-pass density model intends.

GPU compatibility

Sculptured Varnish no longer renders pages black on certain Macs

A driver-level edge case caused the entire page to render solid black on some Mac GPU configurations whenever Sculptured 3D Varnish was enabled — affecting customers we'd never have known about if it weren't for two reports landing on the same day. The shadow pass now contributes a guaranteed no-op outside the varnish region, eliminating the dependency on per-driver behaviour for tangents, bump sampling, and NaN propagation entirely. Sculptured Varnish now renders identically across every Mac configuration we've tested.

If you'd previously seen this and assumed V3R was broken for you, please give it another go — you should now see exactly what was always intended.

Multi-page jobs

Add Layer no longer disturbs other host pages

Importing a companion PDF on host page 2 used to corrupt the underlying TIFFs for host pages 1 and 3 — switching to those pages would show the companion's content rather than the host's original artwork. V3R now snapshots every page's textures into memory before the rip, so all host pages survive an Add Layer cleanly. Safe for jobs of any length.

Lamination state

Page switches and file loads reset matte properly

Lamination settings, matte uniforms, and burn-back masks are now flushed cleanly on every PDF reload and page switch. Previously, residue from a laminated page could carry over and tint the substrate of an unrelated file or page until you toggled lamination off and on again.

All Layers toggle

Bulk visibility toggle now syncs matte and burn-back

Hiding all layers via the bulk toggle used to leave a phantom matte tint and any burn-back imprint on the substrate, since the per-layer change handlers were bypassed. The toggle now correctly rebuilds the burn-back mask and re-syncs lamination uniforms in both directions, so Show All / Hide All matches what you'd expect.

Layer naming

Remapped foil layers use the canonical name

Mapping a Duplo or custom-spot layer to one of the dedicated foil colours now updates the sidebar entry to show the foil name — Gold Foil, Red Foil, etc. — rather than retaining the source separation's name. The remapped layer also routes through the correct foil controls instead of falling back to a generic catchall.

Lamination presets

Save and restore matte settings completely

Saving a lamination preset now captures the full state — gloss level, matte texture strength, and matte veil intensity — and restores all three faithfully on load and on factory default. Earlier presets only stored a subset of the controls, leading to mismatched results when reapplying a saved look.

Previous Release v1.1 — Render the extraordinary, more reliably April 2026

A weekend of careful work landed across the V3R suite — three new finishing effects, a smarter Layer Mapping Manager, and a stack of paper-cut fixes that smooth the workflow from import to output.

What's new

3 new effects
New finishing effect

Custom-coloured Holographic Foil

Holographic foil is no longer locked to a single look. Pick any base colour you like — gold, copper, soft rose, midnight blue — and V3R applies the rainbow diffraction pattern over the top, preserving your colour while adding the spectral shimmer.

Useful when a customer's brand calls for something more refined than full-rainbow holographic. A gold holographic foil reads as luxury foil first, with the rainbow as a subtle catch-the-light moment.

How: Foil layer panel → Foil colour dropdown → Rainbow → adjust the colour picker beneath.
New finishing effect

Holographic Glitter

Spot glitter and base substrate glitter both gain a holographic mode that adds per-grain rainbow shimmer over the existing glitter colour. Each grain shifts independently as the surface tilts, so you get that authentic chaotic sparkle rather than a uniform colour wave across the whole layer.

Three new sliders — Holographic Intensity, Frequency, and Grain Variation — let you dial it from a barely-there iridescence to a full chromatic riot. Works in any glitter colour: pink, magenta, gold, silver, all of them.

How: Glitter layer (or Substrate Controls → Glitter material) → enable Holographic → tune the three sliders.
New finishing effect

Rainbow Holographic Film

A full thin-film simulation for sleeking film and holographic lamination — the kind of finish where the entire surface (or a masked area) shifts through the spectrum as the substrate tilts. Two pattern modes ship with this release: a chaotic Holographic look with patches and sparkle valleys, and a Pillars of Light mode that projects parallel rainbow bands across the surface like a real diffraction grating.

Both modes support full-coverage lamination as well as ink-mask sleeking, so you can simulate film bonded only where pigmented toner sits on the page. A full presets folder is included — save, export, share, and reload your favourite combinations.

How: Click the + Add Layer button → choose Holographic Film → pick Pattern Type, Application Mode, and refine to taste.

Foil presets

Hot Foil Stamping now persists with presets

The Hot Foil Stamping checkbox state is now correctly saved alongside the rest of a foil preset, including across export, import, and Save-as-Default round trips. Previously the toggle appeared to stick during a session but reset on relaunch.

Foil presets

Save-as-Default now persists across restart

Each foil colour (Silver, Gold, Bronze, Red, Blue, Green, Pink, Purple, Rainbow, and Custom) now retains its own independent saved default after quitting and relaunching V3R. A subtle key-naming mismatch was preventing custom-coloured foils from restoring on cold start.

Layer mapping

Remapping added layers no longer breaks the rebuild

When using the Add Layer feature to bring in a second PDF (e.g. a separate Duplo black plate), opening the Layer Mapping Manager afterwards used to crash the scene with a missing-texture error. The manager now correctly preserves the original textures in memory so layers can be remapped freely.

Layer mapping

Cancel preserves the existing layer mapping

If you opened the Layer Mapping Manager just to peek at the current setup and clicked Cancel, an added layer (e.g. a Duplo varnish) used to revert to its source separation type. Cancel now correctly leaves everything as-is.

Layer naming

Mapped layers show their effect name in the sidebar

When you add a layer and map a black separation to Duplo, the sidebar entry now reads Duplo rather than Black. The same applies to flood layers — pick Coating, Lamination, Holographic Film, or any other effect, and the sidebar reflects your choice rather than showing a generic "Flood Layer" label.

Layer mapping

"Remember these mappings" now off by default

The persistence checkbox in the Layer Mapping Manager is now opt-in. This is friendlier for the common case where the same separation name (e.g. "Black") may legitimately mean different effects across different customer files. Tick it explicitly when you want the mapping remembered.

Image capture

PNG capture now correctly handles added layers

Capturing a still image of a file that uses the Add Layer feature now produces a faithful render of the scene — varnish, foil, and lamination layers all composite correctly in the saved PNG, matching the live preview.

Holographic film

Tasteful factory defaults for Holographic Film

The initial settings for newly-added Holographic Film layers have been retuned. Fresh layers now load with a refined, understated look out of the gate, rather than a chaotic preview that needed five sliders adjusted before it looked right.
