Abstract

Un aparato y método para corregir las características de impresion de una cabeza de impresion de línea completa, y producir una cabeza de impresion de calidad de impresion elevada a alto rendimiento de fabricacion, una cabeza de impresion corregida mediante este aparato y una impresora que emplea esta cabeza de impresion. De conformidad con este método, se imprime una imagen sobre un medio de impresion usando impulsos dobles obtenidos basándose en la fluctuacion de la resistencia de cada unidad de impresion de una cabeza de impresion, y se determina un valor de OD de referencia de un histograma de valor de OD de la imagen impresa. Se selecciona un ancho de impulso de precalentamiento basándose en los valores de OD de n imágenes impresas obtenidas cambiando el ancho del impulso de precalentamiento n veces y el valor de OD de referencia, de tal manera que un valor de OD en cada elemento de impresion es igual o semejante al valor de OD de referencia. Por ejemplo, suponiendo que el valor de referencia es de 0.43, un ancho de impulso de precalentamiento en el elemento de impresion numero 3 es de 0.875 microsegundo.
