+ELECTRONIC SERIGRAPHY:
+ELECTROLUMINESCENT POSTERS
+During last semester’s class “Printed Electronics: Squeegee, brush, and multimeter”, offered by the Interface
+Design Group, we explored the technical and artistic possibilities of screen printing. All participants first
+printed an individual two colour poster design relating to the topic of Art and Technology. By making use of
+printed electronics, an electroluminescent shape is created on the posters. When a voltage is applied, the
+shape will light up, serving as a flexible lamp.
+During our working sessions in the facilities of the Interface Design Group we concentrated on the aspects of
+printed electronics. To explore the artistic possibilities of screen printing we had the opportunity of visiting the
+screen print workshop at Gerberstraße, led by Adrian Palko and Max Roßner, for an excurision.
+Electroluminescence works like a capacitor, two electrodes
+are seperated by a dielectric, producing an electromagnetic
+field. Inbetween the two electrodes lies a layer of phosphor.
+When an alternating current is applied, it causes the
+electrodes within the phosphor to move, when they fall
+back into their original state, the phosphor actively emit
+light.
+The four layers that are needed to create
+electroluminescence can be printed with screen printing
+using special inks. The bottom electrode is printed with
+a conductive ink containing silver particles. A dielectric
+ink seperates the electrodes. The layer that emits light is
+printed with an ink which contains phosphor particles. It is
+of pink colour but will create a blue light. The top layer is
+printed using a different type of conductive ink. This layer is
+translusive enabling the light to shine through.
+All of the inks used in the process were kindly provided to
+us by InnovationLab Heidelberg.
+The term Serigraphy was coined by Anthony Velonis and Richard Floethe, a former Bauhaus student, of the
+Federal Art Project in New York in the late 1930ies. It is not a seperate technique, but simply a label for the
+use of screen printing for artistic purposes.
+Many artists have explored screen printing during the last 100 years, among them are Bauhaus Masters Josef
+and Anni Albers, or pop artists like Andy Warhol and Corita Kent. During the course of this class, we intended
+to combine serigraphy and printed electronics.
