A system and method for generating a master screen for a silk screen imaging process. Photo activated emulsion is applied to a printing screen and the emulsion is exposed according to a digitized pattern using a light emitting diode (LED) source. The LED source in one embodiment is an array of UV emitting devices which scans the printing screen in a line by line basis.
L'invention concerne un système et un procédé permettant de générer un écran maître pour un procédé d'imagerie de type sérigraphie. L'émulsion d'activation de photo est appliquée sur un écran d'impression et l'émulsion est exposée selon un motif numérisé utilisant une source de diode électroluminescente (DEL). La source DEL, selon un mode de réalisation, est un réseau de dispositifs émetteurs d'UV scannant l'écran d'impression selon un mode ligne par ligne.
