Abstract

Una cabeza de impresión de chorro de tinta de tipo de gota sobre demanda,de tamaño de punto modulable, y métodos asociados para expulsar gotitas devolumen modulale de tinta desde la misma. La cabeza de impresión de chorrode tinta incluye una parte de cuerpo principal que tiene primero y segundocanales portadores de tinta que se extienden longitudinalmente a través dela misma, y una placa de cubierta fijamente montada a ella. En la placa decubierta se forma un orificio adelgazado que se extiende desde las primeray segunda aberturas a lo largo de una superficie lateral posterior, hastauna tercera abertura a lo largo de una superficie lateral frontal de lamisma. La placa de cubierta se monta en la parte de cuerpo principal, detal manera que la primera abertura está en comunicación con el primercanal portador de tinta, y la segunda abertura está en comunicación con elsegundo canal portador de tinta. La cabeza de impresión de chorro de tintaincluye además primero y segundo accionadores acoplados con los primero ysegundo canales portadores de tinta, respectivamente. Se pueden expulsargotitas de volumen modulable de tinta desde la cabeza de impresión dechorro de tinta, aplicando simultáneamente un impulso de voltaje que tengauna magnitud seleccionada al primer canal portador de tinta y un impulsode voltaje que tenga una magnitud entre cero y la magnitud seleccionada,al segundo canal portador de tinta. De una manera alternativa, las gotitasde volumen modulable de tinta se pueden expulsar desde la cabeza deimpresión de chorro de tinta aplicando en secuencia un impulso de voltajeque tenga una duración de tiempo seleccionada, al primer canal portador detinta, y un impulso de voltaje que tenga una duración de tiempo entre ceroy la duración de tiempo seleccionada, al segundo canal portador de tinta.A modulable dot size, drop on demand ink jet printhead and associated methods for ejecting modular ink volume droplets therefrom. The inkjet print head includes a main body part having first and second ink carrier channels extending longitudinally therethrough, and a cover plate fixedly mounted thereto. A thinned hole is formed in the cover plate which extends from the first and second openings along a posterior lateral surface to a third opening along a frontal lateral surface thereof. The cover plate is mounted on the main body part, detailing so that the first opening is in communication with the first ink carrying channel, and the second opening is in communication with the second ink carrying channel. The ink jet print head further includes first and second actuators coupled with the first and second ink carrier channels, respectively. Variable volume droplets of ink can be ejected from the ink jet print head, simultaneously applying a voltage pulse having a selected magnitude to the first ink carrier channel and a voltage pulse having a magnitude between zero and the selected magnitude, to the second ink carrier channel. Alternatively, the modulable volume ink droplets can be ejected from the ink jet print head by sequentially applying a voltage pulse that has a selected time duration, to the first ink carrier channel, and a voltage pulse that has a time duration between zero and the selected time duration, to the second ink carrier channel.
