Full title and description

STB BS IEC 62899-302-1:2017 — Printed electronics — Part 302-1: Equipment — Inkjet — Imaging based measurement of jetting speed. This document defines a vision‑based measurement method for determining inkjet droplet jetting speed from visualized droplet images obtained by a drop analysis system.

Abstract

Specifies a standardized procedure to measure inkjet drop speed using image sequences captured by drop‑analysis/vision systems, including test setup, image processing algorithm and analysis of jetting behaviour. The method applies to drop‑on‑demand inkjet systems and is not intended for continuous inkjet. It supports evaluation of jetting performance for printed electronics and related precision dispensing applications.

Scope

Defines the measurement procedure and data analysis for determining droplet jetting speed from high‑speed imaging of inkjet droplets. The scope is limited to drop‑on‑demand type inkjet heads used in printed electronics and precision dispensing; it excludes continuous inkjet technologies. The standard covers test arrangement, image acquisition, image‑processing algorithms and interpretation of jetting behaviour for evaluation and comparison of jetting performance.

Key topics and requirements

• Definition of required test setup and environmental/conditioning considerations for reproducible imaging measurements.
• Image acquisition parameters (frame rate, lighting, optical alignment) and recommended capture practices for droplet visualization.
• Image‑processing algorithm and steps to extract droplet position, timing and compute jetting speed from sequences of images.
• Requirements for data analysis, presentation of results, and basic considerations for uncertainty and repeatability.
• Limitation to drop‑on‑demand systems; explicit exclusion of continuous inkjet.

Typical use and users

Used by printed‑electronics equipment manufacturers, ink and print‑head developers, process and metrology engineers, R&D laboratories and quality/control teams to characterise and compare inkjet jetting performance, to tune formulations and printing parameters, and to validate equipment behaviour during process development and supplier assessment.
