Abstract: A method for executing a discrimination process of a printing medium includes a step (a) of preparing N machine learning models when N is an integer of 1 or more, a step (b) of acquiring target spectral data which is a spectral reflectance of a target printing medium, and a step (c) of discriminating a type of the target printing medium by executing a class classification process of the target spectral data using the N machine learning models.

Abstract: A first provider for providing a printer, a second provider for providing a print medium, a client which performs printing on the print medium using the printer, and a management section for processing and storing information are coupled to each other via a network. The first provider provides the second provider with a provider printer and a profile preparation tool. The second provider executes a process of preparing a profile corresponding to a combination of the provider printer and the print medium using the same, and transmitting printing setup information including the profile to the management section with respect to one or more print media. The client receives the printing setup information corresponding to the combination of the client printer used in printing and the print medium used in printing from the management section, performs setup based on the printing setup information on software for controlling the client printer and performs printing.

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.

Abstract: A profile adjustment system adjusts a profile to be used for converting a coordinate value in a color space, based on an adjustment target at an adjustment point indicating a color to be adjusted. The profile adjustment system includes a coordinate receiving unit configured to display on a display unit an input field for coordinates of the adjustment point, and to receive an input of the coordinates of the adjustment point, and a color display processing unit configured to display on the display unit a color corresponding to the coordinates, the input of which has been received, in association with displaying of the coordinates.
