Latest Patents

Among his latest patents, Nakazawa has developed innovative inkjet recording methods that enhance the quality and efficiency of color image formation. One of his notable inventions involves a method that includes forming a color image with color inks while scanning a recording head multiple times over the same area. This method utilizes a recording head with a nozzle pitch ranging from 10 to 50 μm, incorporating color inks that consist of cyan, magenta, yellow, black, and at least one special color ink. The inks are designed to contain pigments, a high boiling point organic solvent, and water, resulting in dots sized between 10 to 50 μm. The recording medium used features a micro-porous layer with inorganic fine particles and a hydrophilic binder, allowing for optimal absorption and image quality.

Another patent focuses on a similar inkjet recording method, which forms a color image on a recording medium by scanning the recording head multiple times. This method creates a thinned-out image based on a non-regular thinning-out pattern. The inks used in this process also contain pigments and a high boiling point organic solvent, with a surface tension ranging from 30 to 50 mN/m. The recording medium in this case also includes a micro-porous layer with fine particles, ensuring high-quality image transfer.
