Latest Patents

Two of Talke's notable recent patents include:

1. **Spot Size Modulation Using Multiple Pulse Resonance Drop Ejection**

This innovative patent describes an ink jet drop-on-demand printing system that features an ink jet print head equipped with an ink cavity. An electromechanical transducer mounted in mechanical communication with the ink cavity receives electrical signals that selectively actuate the transducer to produce ink drops of varying sizes. By producing electrical signals that are spaced by a fixed time delay, which is short concerning the drop-on-demand production rate, this system enables precision in ink drop formation, ultimately merging multiple volumes of ink into a single drop before contacting the print medium.

2. **Gray Scale Printing with Ink Jet Drop-on-Demand Printing Head**

This invention enhances inkjet printing capabilities by adding gray scale functionality. The system incorporates a transducer with multiple separately actuable sections, controlled through print data that specifies the required drop volume. The drive signals actuating the sections can be varied in amplitude and pulse width to precisely control drop volume while maintaining the drop velocity. This flexibility allows for fine-tuned grey scale printing, crucial for high-quality image reproduction.
