Latest Patents

Two of Nakazawa's most recent patents showcase his innovative approach to ink jet technology. The first is an ink jet recording apparatus designed to include an image forming unit that produces an ink image by discharging ink, which contains both a resin and a liquid component. This apparatus features a liquid removing unit that extracts the liquid component from the image, allowing for a cleaner transfer to the recording medium. It also incorporates a fixing unit which employs heating and pressing techniques to ensure the durability of the printed image. Furthermore, the technology includes a liquid adhesion determination unit that assesses the presence of liquid on the fixing substrate, along with a liquid removing condition changing unit that adjusts the removal conditions based on this assessment.

The second patent is an ink jet recording method that develops an image on a recording medium by applying a reaction liquid alongside an aqueous pigment ink and a resin-containing aqueous liquid. The method is characterized by its stepwise application, which ensures effective image formation while maintaining high print quality. Notably, the surface tension of the resin-containing aqueous liquid is calibrated to be higher than that of the aqueous pigment ink, which allows for optimal image integrity.
