More Information
Summary:A print data generator includes a storage storing processor-executable instructions causing a processor to perform a process to generate print data from original full-color data. The process includes when a hue value of a pixel is within a specific hue range for an emphasis color, setting a density value of a reference color of the pixel based on a value value of the pixel, and setting a density of the emphasis color of the pixel based on a saturation value of the pixel and a difference value between the hue value of the pixel and a hue value of the emphasis color, and when the hue value of the pixel is out of the specific hue range, setting the density value of the reference color based on a luminance value of the pixel derived from RGB data, and setting the density value of the emphasis color to zero.
