Joint Meeting of ISCC/ASTM E12/CIE Div. 1
Standards:
What they are - What will they be? - What should they be?

Princeton University, Princeton, NJ
June 14 – 18, 2010

June 14-18 will be a full week of interesting meetings with three organizations. ASTM Committee E12 on Color and Appearance will meet on June 14-15 for their bi-annual committee meetings. The ISCC Special Topical Meeting will be on June 16. Finally, CIE Division 1 will hold their technical sessions and committee meetings on June 17-18. (Registration form)

Wednesday, 16 June Presentations

AM Session 1: The Standards Process
  • Ronnier Luo, Univ. Leeds
    Color and vision in the CIE—now and in the future
    Color and vision are the purview of CIE D1. Current efforts are going toward low-lighting (mesopic) environments, age-dependent vision, 3D goggles that don’t make you sick, green lighting technologies, and a spatial-vision standard observer. Expanding technology calls for expanded attention to visual comfort, safety, and efficiency.
  • Philip Wychorski, Orion Standards LLC
    Standards review process—United States National Committee of the CIE (CIE/USA)
    Participation in standards activities is no longer just an issue of solving technical problems. The CIE/USA like many other organizations is working hard to navigate a path forward to meet not only the technical issues but the challenging financial and organizational issues as well. Come see how the CIE/USA is addressing these important issues.
  • Danny Rich, Sun Chemical
    Documentary standards in graphic reproduction: Pathway to quality or highway to mediocrity
    In the late 20th Century, SWOP, DDAP, and ICC evolved a coordinated program for color control using ink standards and digital color-management systems. But soon the successes induced a veritable feeding frenzy as organizations competed with each other over the “glory” of publishing the next standard. Where will it end?
AM Sesson 2: Fundamental Colorimetry
  • Jan Henrik Wold, Univ. Oslo and Buskerud Univ. College
    XYZ colorimetry—still a relevant concept for a colorimetric standard?
    CIE TC1-36 defined color-matching functions that depend on field size and observer age. When these functions are used to define XYZ coordinates, a possible multiplicity of standard observers arises---so how can we still use XYZ in color technology?
  • Rolf Kuehni, Color Consultant
    Mensurating a perceptual object color solid
    Color-difference models are thwarted by differences in observer and in viewing conditions. Do the same color difference formulas work for different media, or for different ways of visually presenting samples?
  • Wendy Davis, NIST
    Color quality: Where we are; what's next?
    Motivated by the vexing problem of quantifying LED color-rendering, CIE TC1-69 is expanding the notion of color-rendering index, trying such concepts as illuminant rank-ordering, memory color, and perceptual models. The field is moving fast.
LUNCH

PM Session 1: Tristimulus Integration
  • Hugh Fairman, Resource III
    Some Recent Improvements in ASTM Standards on Colorimetry
    The ASTM is leading the way in standards for colorimetry. Precision of description is being enhanced (e.g., for the elusive hue angle), and numerical methods are becoming more accurate (e.g., for bandpass-corrected reflectance and tristimulus integration).
  • Changjun Li, Univ. Leeds
    Tristimulus integration
    Many ways now exist to derive weight sets for computing discretely sampled tristimulus integrals. CIE TC1-71 is resolving which way is most accurate, and then to promote uniformity of practice.
PM Session 2: Multi-Angle Spectrophotometry
  • Dave Wyble et al., RIT and Tech. Univ. Darmstadt
    Repeatability analysis of multiangle spectrophotometers
    Multiangle spectrophotometers produce lots of spectral data—a huge task for statistical analysis. What standardized methods are there for analyzing repeatability and inter-instrument-agreement?
  • Maria E. Nadal, NIST
    NIST Appearance Metrology Program
    Appearance is a main driver of commerce, and control of appearance across national borders depends on standardizing laboratories such as NIST. The NIST allows control of appearance by a multitude of goniometric measurements, all compliant with ISO and ASTM standards. A new five-axis goniometer, operating in-plane and out-of-plane, goes beyond ISO and ASTM, anticipating future requirements.
PM Session 3: Printing
  • Klaus Richter, Berlin Univ. Technol.
    ISO-CIE trend for color output of equally spaced color series and elementary hues IRJGB on displays for eight ambient reflections of ISO 9241-306:2008
    Color-management standards have several cross-cutting goals: Equally spaced color scales, elementary colors that are aligned with device-independent scales, coding efficiency, and insensitivity to such factors as quantization error and veiling reflection. The ISO, CIE, DIN and ICC are developing a common RGB profile-connection space to meet these requirements.
  • Ann L. McCarthy, Lexmark International Inc
    Balancing ´automatic color´ and artistic intent: The role of color standards
    In the early years of photography the promise to users was "you push the button we do the rest." Today, automation in digital color management takes a similar approach—as a result falling short with users who want control over their color results. Can new color interoperability standards enable support for these users?
