    Digitization & Archiving

    Industry Overview

    Image quality testing plays a foundational role in the archiving industry, where the primary goal is to ensure the long-term preservation and accessibility of documents, text, and images of cultural, historical, and legal significance. Image quality testing provides a method for evaluating and controlling scanner and imaging workflow performance, ensuring that digitized materials accurately represent the original content.

    Poor image quality can significantly damage the preservation of cultural heritage. Inadequate resolution, for example, can render small text unreadable, while excessive noise can obscure critical details in manuscripts, maps, and photographs. Color inaccuracies, meanwhile, may alter the interpretation of artworks or historical documents.

    Testing scanner image quality requires advanced test equipment and technology. We offer a wide range of solutions, including multispectral illumination and unique test charts explicitly designed for scanners.

    Main Applications

    A look at the crucial applications when determining the image quality performance of scanners in the archiving industry

    Multispectral Illumination

    Multispectral Illumination

    Multispectral illumination is crucial for visualizing certain inscriptions on objects, texts, or images that are not visible in standard photography.
    Camera Resolution

    Camera Resolution

    Poor resolution can lead to a loss of texture and fine details. It is crucial to evaluate the resolution performance of scanners in the archiving industry.

    Color Accuracy

    Color Accuracy

    Poor color accuracy can lead to false digital representations of the original scanned document, image, or text (e.g., artwork).
    Dynamic Range

    Dynamic Range

    Many old documents and images are only black and white. Dynamic range is vital for understanding how well a scanner reproduces content in both dark and bright areas.

    International Standards Relevant to Archiving

    A look at the essential standards related to the relevant image quality factors of scanners in the archiving industry.

    ISO 12233 - Resolution

    Outlines the metrics and test methods for measuring the resolution and SFR performance of a camera/scanner system.

    ISO 21550 - Dynamic Range

    Outlines the metrics and test methods for measuring the dynamic range performance of electronic scanners.

    Metamorfoze

    A cultural heritage program developed by the National Library of the Netherlands that provides guidelines for ensuring high image quality of preserved documents.

    ISO 19264

    Outlines the metrics and methods for analyzing the performance of imaging systems (e.g., scanners) in the cultural heritage industry.

    Key Products

    Specifically designed test equipment for measuring the performance of scanners in the archiving industry.

    iQ-Multispectral

    iQ-Multispectral

    A multispectral illumination device based on iQ-LED technology that enhances digitization and the preservation of documents, texts, or images.
    Universal Test Target (UTT)

    Universal Test Target (UTT)

    A multipurpose test chart designed to test the image quality of scanners. Multiple image quality factors, including resolution, dynamic range, and color accuracy, can be evaluated with the UTT.
    Scan Reference Chart

    Scan Reference Chart

    A chart with gray steps and color patches for the automatic analysis of each scanned page to determine if a specific page is out of its specifications.
    iQ-Analyzer-X CH

    iQ-Analyzer-X CH

    The Cultural Heritage (CH) edition of the iQ-Analyzer-X is explicitly designed for archiving professionals who use the UTT chart for scanner testing.
