Standard illuminants

Herunder oversigt over hvilket lys din betragterboks bør have. Bemærk at for kommunikation mellem grafisk designer og grafisk underleverandør skal D50 altid anvendes også selvom produktet designes til butikslys (3000 kelvin=F12). For udendørs produkter og f.eks. bilindustri anvendes D65.

*(D50) Best choice for both Industry and graphic arts, neutral reproduction of all colors. Good choice for product viewed in combination light = indoor mix of daylight and incandescent lighting!
