Abstract

Translated fromGerman

Zum Abgleich der Schreibdüsen eines Tintendruckkopfes (DK) wird während eines bidirektionalen Druckervorlaufs für jede Schreibdüse (D1 bis D32) ein definiertes Strich­muster (SCI) auf den Aufzeichnungsträger (P) abgedruckt und anschließend während eines Abtastdurchlaufes von einem Sensor (AB) abgetastet. Die Abtastwerte (AW), welche die "Ist"-Position der Tintentröpfchen repräsen­tieren, werden in der zentralen Steuerung (ZS) der Tinten­schreibeinrichtung mit der durch die Ansteuerimpulse im Druckspaltenraster (DSR) bestimmten "Soll"-Position ver­glichen und ein sogenannter Tröpfchenversatz (VS) ermittelt. Der Tröpfchenversatz (VS), d.h. die ermittelte Differenz wird für jede einzelne Schreibdüse (D1 bis D32),getrennt für beide Schreibrichtungen (L,R), gespeichert und im nor­malen Schreib- oder Druckbetrieb erfolgt für jede Schreib­düse (D1 bis D32) eine Korrektur entsprechend des im Speicher (VPS) abgelegten Versatzes (VS).For matching the writing nozzles of an ink print head(DK) is during a bi-directional printer runa defined line for each writing nozzle (D1 to D32)pattern (SCI) printed on the record carrier (P)and then during a scan ofsensed by a sensor (AB). The samples (AW),which represent the "actual" position of the ink dropletsanimals, are in the central control (ZS) of the inkswriting device with the by the control pulses inPrint column grid (DSR) determined "target" position vercompared and a so-called droplet offset (VS) determined.The droplet offset (VS), i.e. the difference determinedis separated for each individual writing nozzle (D1 to D32)for both writing directions (L, R), saved and in norpaint write or print operation is done for each writenozzle (D1 to D32) a correction according to the imStorage (VPS) stored offset (VS).
