A manufacturing method for manufacturing a colored product, where using inkjet heads which are a plurality of color ink heads, and an inkjet head, which is a colorless ink head, a plurality of coloring regions are formed in an overlapping manner in a normal direction, a surface side colored region, which is a region located closest to the surface of the colored product is formed using at least the color ink ejected from any of the inkjet heads, and an inner colored region, which is a region located farther from the surface of the colored product than the surface side colored region is formed using at least the color ink ejected from any of the inkjet heads and the colorless ink ejected from the inkjet head.

A layer configuration prediction method is provided and includes: a specimen production step of producing multiple specimens by depositing layers of a material in configurations different from each other; a specimen measurement step of performing, on each specimen, measurement to acquire a texture parameter corresponding to a texture; a learning step of causing a computer to perform machine learning of a relation between each of the specimens and the texture parameter; a setting parameter calculation step of calculating a setting parameter corresponding to the texture set to a computer graphics image; and a layer configuration acquisition step of providing the setting parameter as an input to the computer having been caused to perform the machine learning, and acquiring an output representing the layering pattern of layers of the material corresponding to the setting parameter.

A printing system is provided and includes an image processing portion that generates a generated image by image processing, and a printing portion that performs printing on a medium based on the generated image. The image processing portion generates the generated image by performing a quantization processing that performs quantization by comparing the pixel value of each pixel in the input image with a threshold, and in the quantization processing, calculates a dot influence value indicating to what extent a position corresponding to a selected pixel is covered by the ink dots formed at the position set on the medium in correspondence with the peripheral pixels of the selected pixel, performs adjustment of reflecting the dot influence value on at least one of the pixel value of the selected pixel or the threshold, and compares the pixel value and the threshold based on a value after adjustment.
