Latest Patents

Sakakibara's latest innovations include a sophisticated image forming apparatus and computer program product that enhances the efficiency of print heads. One of his key patents details a design where the print head for black material ejects later than the cyan, magenta, and yellow materials. This arrangement allows for optimal printing in both forward and backward strokes. The first processing unit in his design converts input image data into CMY image data, subsequently generating black and performing undercolor removal to produce CMYK image data. Additionally, the second processing unit transforms CMY image data, excluding K image data, into data suitable for printing in the backward direction. His inventions demonstrate a thoughtful integration of technology to improve the printing process.

Another significant patent features an image forming apparatus with a unique configuration of nozzle arrays. In this design, a black nozzle array is strategically positioned downstream of the color nozzle array in the sub-scanning direction. This setup works in tandem with a conveying unit to facilitate effective image formation on various recording mediums. The control unit within this apparatus ensures that images can be formed using both color and black nozzles, thus completing an image in a single scanning area efficiently.
