Описание (английский):

This document specifies the procedure for the measurement of a one-dimensional parameter approximating the translucency magnitude of flat materials that absorb and scatter light. This one-dimensional material property is called ‘translucency alpha’ and can be used in appearance-based 3D reproduction workflows ensuring accurate translucency. While the measurement conditions and virtual reference materials used to define translucency alpha are designed for 3D printing workflows, the use of translucency alpha is not limited to reproducing objects with additive manufacturing technologies.

Overview

ISO 19307:2026, published by the International Organization for Standardization (ISO), establishes a standardized procedure for the measurement and one-parameter representation of translucency in flat materials that both absorb and scatter light. The standard introduces the concept of translucency alpha (α), a one-dimensional parameter designed to quantify and communicate translucency magnitude objectively. Translucency alpha provides a robust and reproducible way to represent material translucency, supporting accurate appearance reproduction in 3D workflows, particularly in graphic technology and 3D printing.

While ISO 19307:2026 is tailored for 3D printing scenarios, its methods and the α parameter have broad relevance across any application requiring the representation or comparison of material translucency, regardless of manufacturing or reproduction technology.

Key Topics

Definition of Translucency Alpha (α):

Translucency alpha quantifies the magnitude of light scattering and absorption, offering a standardized material property for describing translucency.
Enables consistent communication of material translucency across digital workflows and devices.

Measurement Procedures:

The standard specifies detailed sample preparation requirements (flat and smooth surfaces, set dimensions).
Relies on colorimetric reflectance and transmittance measurements under controlled lighting (CIE D50) and observer conditions, as outlined in ISO 13655.

Lateral & Vertical Light Transport:

Distinguishes between how light is diffused within materials (lateral light transport: blurring of textures; vertical light transport: transmission revealing occluded objects).
These two phenomena fundamentally determine perceived translucency and are integral to the measurement procedure.

Virtual Reference Materials:

Translucency alpha is referenced to a set of wavelength-independent virtual materials with defined absorption and scattering properties.
The right reference is selected by matching actual measurements to simulated outcomes, ensuring repeatability and comparability.

Adjusting for Scale:

ISO 19307:2026 provides guidance for scaling translucency alpha when reproducing the same object at different sizes-critical for 3D printing applications to ensure visual consistency regardless of model scaling.

Applications

ISO 19307:2026 enhances reliability and consistency for a wide range of practical applications:

3D Printing & Additive Manufacturing: Ensures accurate material appearance reproduction, supporting color and translucency matching in digital fabrication workflows.

Digital Graphic Arts: Facilitates exchange and standardization of translucency information in design files (e.g., RGBA formats), improving color management and visual consistency across devices and media.

Quality Control: Supports objective, repeatable measurement of translucency for flat materials in production or research, aiding material selection and product specification.

Simulation and Rendering: Enables better input parameters for rendering engines and physical-based path tracing, leading to more faithful digital representations of real-world translucent materials.

Related Standards

Professionals implementing ISO 19307:2026 may also reference the following standards for comprehensive workflows in graphic technology and color measurement:

ISO 13655: Graphic technology - Spectral measurement and colorimetric computation for graphic arts images. Provides the underlying measurement protocols used in ISO 19307:2026.

ISO 20795-1: Dentistry - Base polymers - Part 1: Denture base polymers. Offers definitions and context for translucency as it applies to polymers.

3D File Format Standards: Many common 3D file formats (e.g., those supporting RGBA channels) can utilize translucency alpha to ensure consistency between digital and physical renderings.

Aligning with ISO 19307:2026 promotes standardized communication of translucency values, boosts reproducibility in 3D printing and graphic arts, and enables higher fidelity in the visual and tactile representation of translucent materials.
