Abstract: A color correction device includes a color conversion section configured to convert an input value of an input color space into an output value of an output color space, a selection section configured to receive selection of one or more color components as target color components from among a plurality of color components used in a printing device, and a correction section configured to corrects a output value. The correction section configured to, when the input value is a first type input value representing a color that does not include the target color component, execute a first correction process that corrects a first type output value corresponding to a first type input value so as to reduce the target color component. The correction section configured to, when the input value is a second type input value within a propagated correction range set around the first type input value in the input color space, a second correction process that corrects a second type output value corresponding to the second type input value in accordance with a position of the second type input value within the propagated correction range.

Abstract: Image data expressed in a first color space is converted into an expression in a second color space to be used during rendering by using a color conversion profile, and converted image data is generated. A setting related to an application to physically-based rendering is performed on a parameter to be used when performing physically-based rendering on a print medium as a 3D object and related to an appearance of the print medium, the physically-based rendering of a printed print medium on which an input image is printed is performed using the set parameter, and a rendering image corresponding to an appearance of the print medium in a virtual space is displayed in a mode in which a difference in applications of the parameter during rendering is comparable.

Abstract: For a plurality of types of print media, a pre-trained model is prepared, the pre-trained model being generated by machine learning based on spectroscopic information of an unprinted area on the print medium and an identifier indicating the type of the print medium and using the identifier as a trainer. The spectroscopic information of the unprinted area on the print medium to print on is acquired. The acquired spectroscopic information is applied to the pre-trained model. Using a result thereof, auxiliary information about the type of the print medium is outputted. A specification of the type of the print medium using the outputted auxiliary information is accepted. When the type of the print medium is thus specified, printing is performed using a print condition suitable for the print medium.
