Overview
ISO/TR 19312:2026 provides an analysis of methods for predicting print image quality in high-speed inkjet printing systems based on a combination of paper properties. Developed by the International Organization for Standardization (ISO), this technical report supports improved paper selection for advanced graphic technology applications. By leveraging both statistical prediction models and standardized paper measurements, the document helps stakeholders in the printing industry enhance reliability and efficiency of high-speed inkjet print workflows.
Key Topics
- Print Image Quality Prediction: The standard examines procedures to forecast print quality outcomes for high-speed inkjet printing, addressing both coated and uncoated paper types.
- Paper Properties: Key measured attributes include:
- Contact angle of water at multiple time intervals (300 ms, 1,100 ms, 3,100 ms)
- Hygroexpansivity
- Liquid penetration and water absorptiveness
- Silicon content
- Surface pH
- Surface roughness (Parker Print-surf, PPS)
- Statistical Analysis: Utilizes a 'black box' statistical approach, such as logistic regression, to predict acceptability of print image quality based on measured paper properties.
- Comparison to ISO 15397: The paper properties identified in ISO/TR 19312:2026 supplement the data already provided according to ISO 15397, enhancing the ability to evaluate papers not specifically designed for inkjet systems.
Applications
ISO/TR 19312:2026 is valuable for diverse stakeholders in the printing and paper manufacturing industries:
- Paper Manufacturers: Can communicate additional, standardized property data alongside existing specifications, making it easier for customers to select suitable substrates for inkjet presses.
- Printing System Providers & Press Manufacturers: Allows evaluation and classification of existing commercial papers, optimizing press performance and expanding substrate compatibility. Facilitates system testing and benchmarking using standardized measurement protocols.
- Print Service Providers: Reduces reliance on trial-and-error paper selection by providing a data-driven, predictive approach to choosing substrates that will yield high-quality results on high-speed inkjet equipment.
- Research and Development: Offers a foundation for further innovation in print quality prediction and digital print process optimization, encouraging collaboration between paper scientists and print technologists.
- Quality Assurance: Enhances quality control processes by providing measurable and comparable data on paper properties that influence print outcomes.
