A comparison area detection unit of image processing circuitry detects an image area of a fading determination object on the basis of an image signal generated by an image capturing unit using a color filter as a comparison area. A color information generation unit generates color information from the image signal of the comparison area and uses the color information as comparison target information. A color information comparison unit compares the color information of the fading determination object as fading determination reference information with the comparison target information. A fading information generation unit generates fading information indicating that a fading level of the color filter exceeds a predetermined level or the fading level of the color filter on the basis of comparison information indicating a comparison result between the fading determination reference information and the comparison target information. The fading state of the color filter can be detected with precision.

20230342091 · 2023-10-26 ·

A method for color calibration of a print device is provided. The method includes receiving, at the print device, a print job request that includes a color print job, determining, at the print device, print job data including data associated with the color print job and the print device, wherein the data associated with the print device includes an ambient temperature sensed by an embedded temperature sensor in the print device, and transmitting, by the print device, the print job data to a cloud server to request a stored matching color profile having associated data that matches, within a defined threshold, the print job data. Using techniques disclosed herein, printer calibration is automated using big data analytics (i.e., continuous learning, analyzing, and optimizing). A spectrophotometer and temperature sensor are embedded into the print device and a printer bot, as a helper printer-resident application, builds a data module and automates the calibration process; a calibration profile is generated for each print job based on the current printer, paper, ink, and the room temperature. A non-transitory computer-readable medium and print device are also provided.

Compensating over-saturation due to dye-enriched colorant

A method is described in which image data of an image to be printed is obtained wherein the image data includes data of each colorant to be printed. The image data of each colorant to be printed is analysed to detect areas of the image in which dye-enriched colorant will occur during printing. The image data is modified to compensate for over-saturation due to the dye-enriched colorant in the detected areas and the image is printed based on the modified image data.
