TAMS High Gloss

The TAMS HG (High Gloss) module provides a complete, perception‑based evaluation of clear‑coat and other high‑gloss surfaces by combining Contrast, Sharpness, Waviness and Dimension into the Quality (Q) and Harmony (H) indices. It is designed to show how smooth, deep and consistent a finish appears to the human eye, going far beyond simple gloss readings.

Purpose of this module

Quantify all key contributors to high‑gloss appearance, including contrast (colour impact), image sharpness, orange peel/waviness and dominant texture size on coated or polished surfaces.

Provide perception‑aligned Quality and Harmony metrics that match measured values to what people actually see, reducing disagreements between plants, suppliers and OEM appearance engineers.

Where this module can be used

High‑gloss exterior and interior coatings in automotive and commercial vehicles, including body panels, bumpers, mirrors and add‑on parts.

Other reflective products such as decorative metals, plastics, appliances and consumer goods where premium, uniform appearance across parts or assemblies is critical.

What this module measures

Contrast, Sharpness, Waviness and Dimension: Core TAMS parameters describing colour‑dependent impact, clarity of reflections, orange peel strength and dominant texture scale at showroom distance.

Quality (Q) and Harmony (H): Single‑number indices predicting overall appearance quality and the visual match between adjacent parts, so you can judge both individual surfaces and panel‑to‑panel consistency on a common scale.

How to use this module

In Appearance Elements, select the TAMS HG module, choose the appropriate job or batch, and configure TAMS for C‑Coat high‑gloss measurement using the required algorithm (for example CC‑TAMS‑STD).

Place TAMS on a clean, representative area of the surface, take one or more measurements per part, and store the results in the chosen batch; use guided or manual job modes if you want to follow a defined measurement route around a vehicle or product.

How to interpret the results

Use Quality (Q) to judge how good the high‑gloss finish appears overall and to set pass/fail limits or targets; higher Q indicates smoother, deeper, more mirror‑like surfaces.

Use Harmony (H), together with Waviness, Dimension, Contrast and Sharpness, to see whether adjacent parts match visually and to diagnose whether any mismatch is driven mainly by texture level, texture scale, colour/contrast or clarity.
