GamutFit: Substrate & Press Ranking by Color-Gamut Containment
A tool that tells a designer which paper and ink will best match their colors before they pay for test prints.
A pre-press tool that ranks which paper, ink, and press combination will best reproduce a design's colors, by measuring how much of the artwork falls inside each option's printable color range — before any money is spent on proofs.
Concept
A pre-press decision tool that answers one question before a print job is committed: which paper, inkset, and press will reproduce this design's colors best? The user uploads artwork or a brand palette. The tool extracts the design's colors, pulls pre-measured gamut boundary descriptors (GBDs) for candidate substrate/ink/press combinations from a library, and — using the method for calculating gamut boundaries along given lines — measures how far each color sits inside or outside each candidate's gamut. It returns a ranked shortlist of substrates plus a per-color report (e.g., brand red is well outside gamut on uncoated stock but inside gamut on coated stock with extended inks) and a predicted reproduction-difficulty score based on the source-destination gamut difference. Print buyers choose stock with evidence instead of paying for rounds of hard proofs.
Why now
The paper [0] delivers exactly the computational primitives this product needs: newly developed methods for calculating gamut boundary descriptors and for calculating gamut boundaries along given lines from them, exercised inside a working colour reproduction system that moved five test images from a CRT source to an inkjet-printed destination. Its multi-round psychophysical evaluation also sharpened understanding of gamut difference as a factor in reproduction quality — so the tool's difficulty score can be grounded in a demonstrated relationship (larger source-destination gamut difference, worse mapping outcomes) rather than heuristics. No catalog idea currently addresses substrate or press selection by gamut containment.

AI assessment
A highly focused, technically grounded pre-press tool that replaces expensive physical proofing with a data-driven gamut-containment ranking system.
- Evidence strength 5/5
- The idea directly implements the specific computational primitives (GBDs and line-based boundary calculations) described in the research to solve a real-world reproduction problem.
- Market pull 4/5
- High-end brand owners and packaging firms have a strong financial incentive to reduce the iterative cost and time of physical press proofs.
- Novelty & moat 4/5
- While other catalog ideas handle perceived color shifts, this is the first to focus on the physical containment of colors within substrate/ink gamuts for selection purposes.
- Feasibility 4/5
- The core logic is based on existing mathematical descriptors; the primary challenge is building the library of GBDs for various substrates.
- Wedge clarity 5/5
- The wedge is a sharp, single-purpose tool: ranking substrate/press combinations based on a specific artwork's color requirements.
- Simplicity / focus 5/5
- The product is a single, focused utility with a clear input (artwork) and output (ranked list), avoiding platform bloat.

Who benefits
- Tiffany & Cocompany
Its trademarked Tiffany Blue sits outside standard CMYK gamut; a ranked gamut-fit report across candidate substrates and extended-ink presses would show which print route gets closest before production begins.
- Gelatocompany
Its distributed print network produces the same design on many local substrates; a per-design gamut-fit ranking lets it route each order to the substrate and plant that reproduces that artwork best.
- Hallmarkcompany
Greeting cards are extremely color-critical and are printed on many textured and colored paper stocks; choosing stock by measured gamut fit would cut re-proofing cycles on seasonal card lines.
- Ball Corporationcompany
Beverage-can decoration uses a limited, non-CMYK ink gamut; a gamut-fit ranking lets Ball advise brand customers at the design stage how their palette will map onto cans, before artwork is locked.
