Summary & Discussion
All speakers (except Mr. Druemmer who had to leave early)

The CIE publication about indoor illuminants confirms existing ergonomical standards and is anticipated to have influence on amendments and new standards for workstations and working environment.

UV content and optical brighteners for print and proofprint need more consideration for measured or visual control of colours.

For display and print of colours Prof. Hill said D65 to be easier and more accurate for colour calculations and transformations. This was confirmed by most of the participating speakers. Prof. Schanda lined out the historical dimension of CIELab and the decission to use D65 as whitepoint.

Elementary colours need more evaluation, but probably are able to show ways for more consistent colour workflows.
