Latest Patents

Franzke's latest patents include an "Ink Jet Image Producing Device and Process for Its Operation." This invention involves an inkjet image producing device designed to reproduce digital image data of photographic images. The device features at least one printing head with more than three base colors or inkjet colors, which expands the color space available for printing. A processing device is utilized to determine the location or color coordinates of color values in the image data, which is stretched by the colors of the printing head. Additionally, a determining device identifies the base or inkjet printing colors or mixtures needed to reproduce the color values accurately. The invention also includes a threshold device that manages the degree of coverage of the printing medium, ensuring optimal ink usage.

Another significant patent is the "Automatic Image Quality Determination" process. This innovation allows for the automatic assessment of image quality in inkjet photo printers. A digital reference test chart is produced and printed by the photo printer, generating a specific printout that is then digitized for comparison with an optimal digital reference test chart. This process enables the determination of image quality based on deviations between the printed output and the reference chart.
