摘要:
Ink-jet printhead adapted for printing with hot-melt ink and having a nozzle face (14) provided with an anti-wetting coating (22), wherein the anti-wetting coating contains silicone and/or polysilane as main component(s) and has a wetting angle of at least 40° and shows a decrease of the wetting angle of not more than 5% per 100 days of exposure in hot-melt ink.
摘要:
Method for manufacturing pellets (34) of hot-melt ink, characterized by the steps of:
filling molten ink (18) into a mold cavity (16) defined between a first die (12) and a second die (14) of a mold (10), allowing the ink (18) to cool down and to solidify in the mold cavity (16), and heating at least one of the first and second dies (12, 14) for re-melting the surface of the ink pellet (34) to be removed from the mold cavity (16).
