Full title and description

Graphic technology — Multispectral imaging measurement and colorimetric computation for graphic arts and industrial application — Part 1: Parameters and measurement methods. This part defines parameters and measurement methods for spatially resolved spectral measurement of reflecting flat objects and procedures to compute colorimetric parameters for multispectral imaging devices used in graphic-arts and industrial applications.

Abstract

This document establishes procedures for spatially resolved spectral measurement of reflecting flat objects (including inline colour measurements) and for the computation of colourimetric parameters from multispectral imaging devices intended for graphic-arts and related industrial uses. It excludes spatially resolved measurements of transmitting or self‑illuminating objects (e.g., flat‑panel displays), step-and-repeat spot-reading scanners and printing on metallic or interference foils.

Scope

Specifies measurement parameters and methods for multispectral, spatially resolved spectral measurements of reflecting flat objects and the colorimetric computations derived from those measurements for graphic‑arts and industrial applications. The standard is intended for devices that produce spatially resolved spectral data (including inline systems) and defines what is in‑scope and what is excluded (for example, transmitting/self‑illuminating media, spot-reading scanners, and metallic/interference foils).

Key topics and requirements

• Definitions of parameters for multispectral imaging measurement and spatially resolved spectral capture.
• Procedures for spectral data acquisition and handling for reflecting flat samples, including inline measurement considerations.
• Methods to compute colourimetric values (tristimulus and derived colorimetric parameters) from multispectral image data.
• Exclusions and limitations: not applicable to transmitting/self‑illuminating objects (e.g., displays), step‑and‑repeat spot scanning instruments, or metallic/interference foils.
• Test and reference conditions implied or referenced for consistent measurement in graphic arts contexts.

Typical use and users

Used by color‑measurement device manufacturers, print and quality control engineers, prepress and production printing specialists, metrology labs and R&D teams working on multispectral imaging for graphic arts and industrial surface measurement. Typical applications include inline production colour monitoring, spectral image capture for quality assurance, and converting multispectral data to standardized colourimetric values for process control.

Q: What does it cover?

A: It covers procedures for spatially resolved spectral measurement (including inline measurements) of reflecting flat objects and the calculation of colorimetric values from multispectral image data; it explicitly excludes transmitting or self‑illuminating objects, step‑and‑repeat spot‑reading scanners and printing on metallic/interference foils.

Q: Who typically uses it?

A: Device manufacturers, print production and quality engineers, prepress specialists, metrology laboratories, and researchers working with multispectral imaging systems in graphic arts and industrial surface measurement.

Q: Is it current or superseded?
