An inkjet printer injects first ink of a plurality of colors and second ink. An extraction condition setter sets an extraction condition to extract a portion of, or an entirety of, ink dots of the first ink of each of the plurality of colors. An extractor extracts an underlying layer dot group from ink dots of the first ink of each of the plurality of colors based on the extraction condition. Such a plurality of underlying layer dot groups and ink dots of the second ink form a first printing layer. An image dot group including at least the ink dots, of the first ink, other than the underlying dot groups forms at least one additional printing layer.
