Abstract

PURPOSE:To prevent the resonance between a spurious vibration and vibration of a piezo-electric element and improve the quality of printing checking the generation of satellite particles by holding the resonance frequency of the piezo- electric element within 5 in terms of the pressure propagation ratio between a pressure chamber and a conduction path. CONSTITUTION:The ratio between a pressure Po generated in a pressure chamber and a pressure P on the surface of a nozzle (pressure propagation ratio) varies in the frequency characteristic with the shape of a conduction path. The use of a nozzle possible elevating said pressure propagation ratio to 6 or more greatly affects the particle-making property of ink leading to the generation of satellite particles 14 in the ink injected from a nozzle 9. This will also disturb meniscus vibration so much to allow the infiltration of bubble. To solve the problem, the resonance frequency of the piezo-electric element is held within 5 in terms of the pressure propagation ratio.
