Latest Patents

Ihara's latest patents include a printer, printing system, and card manufacturing method. One of his inventions involves an input unit that receives first image data to be printed with a first ink. A luminance value calculator determines the luminance value of each pixel in the first image data. The luminance value converter then adjusts these values to fit within a previously set luminance range. The printing unit utilizes these converted values to print the first image on a print body, while also printing a second image with a glossy second ink, resulting in a superimposed glossy image. Another patent focuses on a method where a density acquisition unit obtains the density value of each pixel in the first image data. A glossy image density decision unit sets the gloss density value based on predetermined criteria, and a dithering processor creates second image data for a second print image. This method allows for the effective transfer of both images onto a print body, enhancing the overall quality of the glossy image produced.
