Title: Dung D Do: Innovator in Ink Jet Technology
Introduction
Dung D Do is a notable inventor based in Burbank, CA (US). He has made significant contributions to the field of ink jet printing technology. With a total of 3 patents to his name, Dung has focused on innovations that enhance the performance and quality of ink jet printers.
Latest Patents
Among his latest patents is the "Interlaced Ink Jet Printer." This invention introduces a row-interleaved printing method designed for phase change ink jet printers. It minimizes appearance abnormalities when printing solid geometric shapes and reduces the horizontal 'banding effect' caused by cross-talk between ink jets when all jets are activated. Additionally, it addresses the 'seaming effect' that occurs due to paper step mechanisms when different velocity profiles are used during printing.
Another significant patent is the "Ink Jet Nozzle Crosstalk Suppression." This innovation involves an ink jet printer with multiple ink jet channels that can be individually controlled to produce ink dots on a printing medium. The patent describes a method to reduce crosstalk by activating each odd-numbered channel in alternation with each even-numbered channel. It also compensates for the time difference between activations by offsetting the orifices of one group of channels from the other. Furthermore, the voltage supplied to excite the channel transducers is varied based on the number of channels simultaneously exited, ensuring a fixed excitation voltage across each transducer.
