Title: **Innovative Contributions of Wolfgang Hettler in Inkjet Printing Technology**

Introduction

Wolfgang Hettler, a prominent inventor based in Feldkirchen-Westerham, Germany, has made significant contributions to the field of inkjet printing. With two patents to his name, Hettler's work focuses on enhancing the performance and quality of ink print heads, which are critical for producing high-quality printed materials.

Latest Patents

Hettler's latest patents showcase his innovative approaches to solving challenges in inkjet printing technology. His first patent details a **method and device for controlling printing elements of an ink print head**. This method involves determining an idle time between the ejection of two dots from the same nozzle. When this idle time exceeds a predetermined threshold, a specific number of vibration cycles are performed. The number of cycles is based on how long the idle time lasts, aiming to improve print quality.

His second patent addresses the issue of **system-dependent streaking** in inkjet printing systems. This patent presents a method where different nozzles of a print head are activated to eject a nominal ink quantity using varying ejection pulses. This approach compensates for non-uniformities between nozzles caused by crosstalk, thereby reducing unwanted streaks in print images.
