ISO 19307:2026 - One-Parameter Representation of Translucency for Graphic and 3D Technologies

Graphic technology — Measurement and one-parameter representation of translucency

ISO 19307:2026 introduces the concept of 'translucency alpha'—a new one-dimensional parameter for quantifying the translucency of flat materials that absorb and scatter light. Its primary aim is to support accurate appearance-based reproduction workflows in 3D printing and graphic technology, where traditional additive color models fail to account for real-world translucency. By defining robust measurement procedures and reference conditions, this standard enables practitioners to assign, match, and adjust translucency characteristics in both virtual and printed objects.

Material scientists, 3D content developers, and graphic engineers will find this standard essential for applications ranging from additive manufacturing to digital rendering and visual appearance assessment.

Key highlights:

• Defines and quantifies 'translucency alpha' for reproducibility in 3D and graphic workflows
• Applicable measurement and simulation methods for various materials
• Direct enablement of perceptual consistency in digital and physical additive processes
