Claim 5:
6. A non-transitory computer-readable medium having instructions stored therein to cause at least one processor to perform functions for color calibration of a print device, the functions comprising:
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;
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;
receiving, at the print device, a communication from the cloud server indicating that no stored matching profile exists at the closed server,
printing, by the print device, a physical representation of an embedded color calibration chart, wherein the embedded color calibration chart is stored, in advance, on the print device and comprises a plurality of different color patches each having a known color value in an independent color space,
measuring, by an embedded spectrophotometer in the print device, color information to determine offsets between color values of patches in the physical representation of the embedded color calibration chart and the known color values of patches in the stored color calibration chart,
generating a color profile from the determined offsets; and
printing, at the print device, the color print job by applying the generated color profile to the color print job.
