摘要： A method for building an image determination model that determines whether a print image is a good image or a failure image includes a step of determining whether the print image is a high-density image or a low-density image; a step of generating teaching data by combining pseudo-failure data with to-be-combined image data, based on a result of the determination; and a step of performing machine learning. Regarding the combining of the pseudo-failure data, for a print image determined to be the high-density image, low-density pseudo-failure data is combined with to-be-combined image data, and for a print image determined to be the low-density image, high-density pseudo-failure data is combined with to-be-combined image data.

摘要： A printing apparatus includes a head part, an encoder, a tension sensor, a head part temperature sensor, an edge sensor, an estimation part, a storage, and an output part. The estimation part estimates print quality in terms of a page printed by the head part on the basis of variation elements detected by the encoder, the tension sensor, the head part temperature sensor, and the edge sensor. The storage stores print quality information containing the printed page and the print quality estimated by the estimation part in association with each other. The output part outputs the print quality information to a display, a post-processing device, and a printer controller section.

摘要： Disclosed is an inkjet printing apparatus including a printing head, an overcoating head discharging an overcoating agent, and a controller operating the printing head and the overcoating head to perform printing to a print medium. The controller operates in a normal discharge mode having a printing rate in the print medium relative to a given area of less than 100% for printing to the print medium, and an inspecting discharge mode having a printing rate in the print medium relative to the given area higher than the printing rate of the normal discharge mode for confirming a discharge state of the overcoating agent. In the inspecting discharge mode, the controller operates the printing head to form an inspecting region on the print medium, and operates the overcoating head to discharge the overcoating agent onto the inspecting region, whereby an overcoating inspecting chart is formed.
