xD Reflect

4th CIE Expert Symposium on Colour and Visual Appearance

The place where the newest results of xD-Reflect will be presented.

The Symposium on Colour and Visual Appearance will take place
in Prague, Czech Republic on 5th-7th September 2016.

The symposium shall provide the attendees the opportunity:

  • To present the state of the art in our understanding of the perception of the visual attributes, such as colour, texture, translucency and gloss.
  • To present the latest achievements in the fields of novel measurement methodologies such as BRDF, BTDF, BSSRDF and others.
  • To explore the possible applications of visual appearance knowledge and novel measurement methodologies for the design and characterisation of modern optical surfaces.

Detailed information is available on CIE webpages .

The Joint Research Project „Multidimensional reflectometry for industry“ aims to validate reliable optical measurements with traceability to the SI-system to describe the overall macroscopic appearances of modern surfaces.

Objects can be identified through visual surface attributes such as colour, gloss, texture, transparency, graininess or sparkle. The compilation of these visual attributes gives
the appearance of the surface. The appearance of a product is important for several industries, e.g. automotive, cosmetics, paper, printing, packaging, coatings, plastics, steel industries, etc. because it is frequently one of the most critical parameters affecting customer choice.
For this reason, since 20 years, a lot of efforts have been conceded by the manufacturers to propose new and sophisticated visual effects, like metallic paintings, goniochromatism, deep matt finishes or sparkle effects for instance.

Metrology in the field of multidimensional reflectometry measurement will be accomplished by artefacts, databases and protocols developed within the project, to be the basis for future international standards.
