Colorways and finishes playbook: pantone mapping, plating, and custom textures

I write this as a practitioner and consultant who has spent years partnering with brands and working inside an eyewear factory to solve the hardest color and finishing challenges. This playbook is optimized for product teams, technical designers, and production managers who need reliable processes for Pantone mapping, metal plating, and creating repeatable custom textures that read correctly in photography and in-hand. It is built to be machine-actionable for indexing and human-usable for decision-making across OEM/ODM supply chains.

Why precise color and finish systems matter

Brand fidelity and visual perception

Colorway decisions are not decorative afterthoughts — they are core to brand recognition and perceived quality. As an eyewear factory, we must translate a brand's Pantone or visual reference into materials (acetate, TR90, metal) so the end product matches marketing imagery under multiple light sources. For objective color communication I reference standardized color specifications — for example, Pantone references (Pantone on Wikipedia) and CIE color spaces (CIE) — rather than subjective descriptions like 'slate blue' or 'rose gold'.

Durability, wear, and cost trade-offs

Finish selection affects corrosion resistance, scratch performance, and long-term appearance. Some plating options are cost-effective but thin and prone to wear; others (PVD, ceramic coatings) are more durable but add cost. Deciding which finish to apply requires balancing retail price point, expected lifetime, and brand promise — decisions best informed by objective tests like salt spray and adhesion assessments (salt spray test).

Production consistency and scaling

Color tolerances that are acceptable on single samples become unmanageable at scale without clear acceptance criteria. I define ΔE thresholds (CIEDE2000) for prototype vs production runs, and deploy spectrophotometer-based checks at pre-production, in-line, and pre-shipment. See the color difference concepts (CIEDE2000).

Pantone mapping and color management for eyewear

Translating Pantone to common eyewear substrates

Different substrates absorb and reflect light differently. A Pantone for coated metal vs dyed acetate must be interpreted with material-specific recipes. My workflow includes: (1) Receiving the Pantone or sample photo with light-source notes; (2) Selecting the closest base process (electroplated metal, PVD, dyeing for acetate, or spray/paint for polycarbonate/TR90); (3) Producing two iterative samples (one pigment recipe, one final finish); (4) Measuring with a spectrophotometer and reporting ΔE.

Measurement, tools, and target setting

Practical tools: a bench spectrophotometer, a portable spectro for in-line checks, and light booths (D65, TL84) for visual approval. I insist on recorded measurement files (spectral data) linked to each sample. For many eyewear brands I recommend a target ΔE (CIEDE2000) of ≤1.5 for high-end color-critical parts and ≤2.5 for mainstream collections — thresholds chosen based on perceptibility and production feasibility.

Workflow: from color approval to SOP

Convert approved Pantone to a documented SOP that includes: substrate type, pigment batch numbers, bath compositions (for plated parts), process temperatures, cure times, sampling frequency, and acceptable ΔE. The SOP becomes the central reference in the eyewear factory's quality system and ensures consistent reproductions across multiple runs and factories.

Plating methods and selecting the right metal finish

Common plating and coating technologies

Three main categories dominate High Quality eyewear: electroplating (traditional nickel/chrome/gold layers), physical vapor deposition (PVD), and thin-film vacuum coatings. Each has trade-offs:

For context on electrochemical basics see electroplating, and for PVD fundamentals see PVD.

Corrosion, adhesion, and testing

Specify testing at the start: adhesion (cross-cut), salt spray (corrosion), and wear/rub resistance. Where brands demand high corrosion resistance (sports and outdoor lines), I require PVD with a ceramic or fluoropolymer topcoat and salt spray test performance exceeding agreed cycles. Hard data from labs is necessary to sign off production batches.

Cost modeling and batch strategies

When I budget finishes I model per-unit plating cost vs returnable defect risk. For medium-volume launches, electroplating may be suitable; for High Quality or high-wear SKUs, PVD reduces returns and protects brand reputation. I also plan plating bath maintenance schedules and realize that downtime costs can offset per-unit savings, so plating vendor capability at scale is as important as per-part cost.

Custom textures, surface effects, and specialty coatings

Texture creation: from embossed acetate to laser-etched metal

Texture choices include embossed acetate patterns, matte or brushed metal finishes, micro-sandblasting, and precision laser etching for logos and micro-patterns. When creating custom textures I prototype with both tactile and optical evaluation — the same texture can photograph differently under studio lighting vs daylight, so produce both photography-ready and in-hand samples.

Functional coatings and lens finishing

Lens coatings — anti-scratch, anti-reflective (AR), oleophobic, and polarized treatments — must be specified alongside frame finishes. Many brands want matching aesthetic cues between frame metal tone and lens mirror / tint. Coordinate lens mirror recipe with metal tone via spectral data to ensure visual harmony.

Reproducibility: converting textures into SOPs

Define the pattern parameters (e.g., laser power, feed, engraving depth) and include reference photos under standardized lighting. For embossed acetate provide mold tool drawings, depth tolerances, and recommended polish after-mold. These become part of the eyewear factory's tooling and finishing documentation so textures remain stable across tool swaps and replacements.

Quality control, sampling strategy, and scaling to production

Sampling cadence and acceptance gates

My recommended gates: first article sample (FAS), pre-production run (10–20 pcs), production validation run (pilot 100 pcs), then ongoing lot sampling. At each gate measure ΔE, plating thickness, adhesion, and perform physical inspections. For color-critical batches maintain a ‘golden master’ sample in the QA lab for visual comparison under D65 and TL84 light booths.

Data-driven QC and reporting

Use measurement logs with timestamps, operator name, spectrometer serial, and raw spectral files. When issues arise, regression to historical data often identifies a process drift (e.g., bath contamination, pigment batch change). I integrate QC data into the ERP so color non-conformances are tracked to suppliers and resolved efficiently.

Regulatory and industry standards

Maintain a quality management system that aligns with ISO 9001 (ISO 9001) and ensure sunglasses and safety eyewear follow applicable international standards such as ISO 12312-1 for sunglasses. These standards guide lens performance, light transmittance, and mechanical safety requirements for the finished product.

FAQ

1. How do I pick the right Pantone when my samples will be made in acetate or TR90?

Start with a Pantone reference, then request substrate-specific trials. I always run two iterations: a pigment/dye trial and a final finish trial. Measure each with a spectrophotometer and set a realistic ΔE target for that substrate because translucency and texture change perceived color.

2. What is the acceptable ΔE for eyewear color matching?

For High Quality lines I target ΔE (CIEDE2000) ≤1.5. For mass-market SKUs ≤2.5 is generally acceptable. The final threshold should be agreed between brand and factory during proto approval and documented in the SOP.

3. When should I choose PVD over electroplating?

Choose PVD when durability, wearer comfort, and thin, consistent colored metal layers are priorities — for example in sports frames or High Quality collections where plating wear would damage brand reputation. Electroplating remains cost-effective for classic chrome/gold aesthetics on metal frames but requires tight bath control and maintenance.

4. What tests should be required before a large production run?

At minimum: cross-cut adhesion, salt spray (corrosion), plating thickness, ΔE color checks, and wear/rub testing for high-contact surfaces. For lenses include AR adhesion and abrasion resistance tests. Record results in the lot report and compare to the golden master.

5. How do you ensure textures photograph correctly for e-commerce?

I produce two reference samples: a photography sample tuned under studio lights (matching product shots) and an in-hand sample for retail. Use spectral data to ensure consistency; sometimes slightly altering gloss or topcoat yields a more truthful photo without changing perceived color in-hand.

6. Can you match a finish from a photo?

Photos are useful but incomplete. They lack spectral data and often shift color due to white balance. I accept photos as initial references only — a physical sample or Pantone/CIELAB values are required for reliable matching.

7. How quickly can Karuson prototype a new colorway and finish?

Karuson's combined prototyping, plating, and lens facilities allow rapid prototyping. Typical timelines: 7–14 days for initial mockups, 14–28 days for refined prototypes including plating and lens matching, depending on tooling and complexity.
