Energy Curing in Ink Jet Digital Production Printing

摘要

Energy Curable ink has become a popular ink technology choice in both scanning graphics applications and in the increasingly important ink jet digital production area, where single pass print engines are being used or designed. The choice of an ink which remains liquid in the print-head nozzles but which can dry "instantly" on the substrate is advantageous from a print-head stability viewpoint. Various methods of curing are available ranging from LED, UV-mercury lamps of electrode and electrodeless type, UV-excimer, with or without nitrogen inerting through to electron-beam curing. Different markets will require and warrant different strategies and this paper reviews the various aspects of these curing technologies and their suitability for different applications.
