Abstract: Werkwijze voor het vervaardigen van kleurdemonstreermiddelen, de werkwijze omvattende het voorzien in een ondergrond en het aanbrengen van een pigmenthoudende deklaag op de ondergrond, daarin gekenmerkt, dat voor de deklaag een materiaal wordt gebruikt dat onder invloed van straling uithardt en de deklaag na aanbrengen op de ondergrond aan de straling wordt blootgesteld. Tevens inrichting voor het vervaardigen van kleurdemonstreermiddelen omvattende aanvoermiddelen voor het aanvoeren van de ondergrond en aanbrengmiddelen voor het op de ondergrond aanbrengen van de deklaag, daaringekenmerkt, dat de inrichting tevens stralingsgenereermiddelen voor het genereren van de straling, omvat. Tevens kleurdemonstreermiddelen vervaardigd volgens zo een werkwijze. Het gaat dan om middelen voor het demonstreren van kleuren, zoals een kleurenwaaier, een set kleurkaarten of een kleurenstaalboek Het middels de straling uitharden van het materiaal van de deklaag neemt weinig tijd in beslag, en vraagt weinig energie. Een drooginrichting die veel ruimte inneemt en veel energie verbruikt, is nu niet meer nodig. Het uiteindelijke resultaat blijkt in de praktijk van hoge kwaliteit, waardoor het percentage uitval klein is. Ook komen bij het proces geen ongewenste vluchtige organische verbindingen vrij, althans veel minder dan bij gebruikelijke deklagen. Als straling kan bijvoorbeeld een elektronenbundel, zichtbaar licht, infrarood licht of ultraviolet licht worden gebruikt. Met name een materiaal dat onder invloed van een elektronenbundel ten minste gedeeltelijk polymeriseert, blijkt goed te voldoen. De ondergrond kan bijvoorbeeld papier, karton, een metaal, een kunststof, glas, hout of een textiel omvatten. Ook combinaties van materialen zijn mogelijk.
