Abstract
The present invention provides a printing device capable of high-resolution reproduction of documentary images and ensuring satisfactory productivity. Specifically, the invention provides a printing device which ejects only ink or a printing device which mixes/ejects ink and diluent, both of which has at least the periphery of the nozzle member on the side upon which the nozzle opens its mouth made of polybenzimidazole or polyimide.
Claims11
A printing device including a printing head comprising:
- an ejecting medium chamber;
- a first nozzle member including a nozzle orifice and a nozzle body, the first nozzle member in fluid communication with the ejecting medium chamber, the first nozzle member comprising is made of a first polybenzimidazole;
- wherein a periphery of the nozzle orifice comprises a liquid-repellant membrane, the liquid-repellant membrane is made of a second polybenzimidazole;
- and
- wherein the first polybenzimidazole and second polybenzimidazole are different.
A printing device including a printer head comprising:
- a base plate layer having formed therein an ejecting medium chamber;
- a liquid-repellant membrane layer formed on the base plate layer;
- a nozzle member formed in and extending through the base plate layer and the liquid-repellant membrane layer, the nozzle member is in fluid communication with the ejecting medium chamber;
- wherein the liquid-repellant membrane layer is made of polybenzimidazole.
A printing device including a printing head, comprising:
- an ejecting medium chamber;
- a first nozzle member including a nozzle orifice and a nozzle body, the first nozzle member in fluid communication with the ejecting medium chamber;
- wherein a periphery of the nozzle orifice is made of polybenzimidazole and wherein the polybenzimidazole has a water absorbance of 4.0% or less when the polybenzimidazole is left in an open atmosphere of 76% RH for 24 hours.
A printing device including a printing head, comprising:
