Title (EN) THERMAL RESPONSE CORRECTION SYSTEM
(FR) SYSTEME DE CORRECTION DE LA REPONSE THERMIQUE
Abstract: front page image
(EN)A model of a thermal print head is provided that models the thermal response of thermal print head elements to the provision of energy to the print head elements over time. The amount of energy to provide to each of the print head elements during a print head cycle to produce a spot having the desired density is calculated based on: (1) the desired density to be produced by the print head element during the print head cycle, (2) the predicted temperature of the print head element at the beginning of the print head cycle, (3) the ambient printer temperature at the beginning of the print head cycle, and (4) the ambient relative humidity.
(FR)L'invention porte sur un modèle de tête d'impression figurant la réponse thermique d'éléments de têtes d'impression thermiques en fonction de l'énergie fournie aux éléments de la tête d'impression dans le temps. La quantité d'énergie à fournir à chacun des éléments de la tête pendant un cycle d'impression pour produire un point de densité voulue se calcule à partir de: (1) la densité voulue à obtenir par l'élément de la tête pendant un cycle de la tête; (2) la température prévue de l'élément de la tête d'impression au début du cycle de la tête; (3) la température ambiante de l'imprimante au début du cycle de la tête; et (4) l'humidité ambiante relative.
