Patent

CA 2560536

Techniques are disclosed for performing processing, such as striping, staggering, and stitching, on print data prior to printing by a multi-head printer. Subsets of the print data may be stored in multiple stages of buffers and processed in parallel to increase processing efficiency. Print data representing digital photographs may be processed sufficiently rapidly to enable continuous printing of digital photographs at high speeds. Parameters of the system, such as print buffer size and interrupt frequency, may be varied in response to design requirements such as overall system cost.

L'invention concerne des techniques permettant de réaliser le traitement, tel que segmentation, étalement, et piquage, de données d'impression avant d'imprimer au moyen d'une imprimante à têtes multiples. Des sous ensembles des données d'impression peuvent être stockés dans plusieurs étages des tampons et traités en parallèle afin d'accroître le rendement du traitement. Les données d'impression représentant des photographies numériques peuvent être traitées suffisamment rapidement afin de faciliter l'impression en continu de photographies numériques à grandes vitesses. Des paramètres du système, tels que dimension du tampon d'impression et fréquence d'interruption, peuvent varier en réponse à des exigences de conception, par exemple le coût global du système.
