Abstract
In an implementation of printing system calibration, a printing system includes a print unit and a calibration system. The calibration system has a learning mode operable to receive a master calibration page containing color value indicia, and measure the color value indicia to determine target color values each corresponding to a color value indicia. The calibration system can utilize a target color value to calibrate the print unit.
Claims38
A printing system, comprising:
- a print unit;
- a calibration system having a learning mode operable to receive a master calibration page containing color value indicia, and further operable to measure the color value indicia to determine target color values each corresponding to a color value indicia;
- and
- wherein the calibration system is configured to utilize one or more of the target color values to calibrate the print unit;
- and
- wherein the calibration system has a normal mode that can be that can be selected as an alternative to the learning mode, the normal mode being operable to calibrate the print unit according to the one or more target color values.
A printing system, comprising:
- a print unit;
- a calibration system having a selectable one of:
- a learning mode operable to receive a master calibration page containing color value indicia, and further operable to measure the color value indicia to determine target color values each corresponding to a color value indicia;
- and
- a normal mode operable to calibrate the print unit according to one or more of the target color values;
- wherein at least one of the learning mode and the normal mode is selected via a user interface.
One or more computer-readable media comprising computer-executable instructions that, when executed, direct a printing device to (i) receive a master calibration page containing color value indicia, (ii) measure the color value indicia to determine target color values each corresponding to a color value indicia, (iii) utilize one or more of the target color values to calibrate a print unit, and (iv) initiate a calibration system operable to identify a designation area of the master calibration page that distinguishes the master calibration page from a local calibration page.
One or more computer-readable media comprising computer-executable instructions that, when executed, direct a printing device to operate in a selectable one of a learning mode and a normal mode:
- when in the learning mode, receive a master calibration page containing color value indicia and measure the color value indicia to determine target color values each corresponding to a color value indicia;
- when in a normal mode, calibrate a print unit according to one or more of the target color values;
- and
- direct the printing device when in the learning mode to identify a designation area of the master calibration page that distinguishes the master calibration page from a local calibration page.
A method for calibrating a printing device, comprising:
- receiving color value indicia;
- measuring the color value indicia to determine target color values each corresponding to a color value indicia;
- utilizing one or more of the target color values to calibrate the printing device;
- and
- identifying a designation area of a master calibration page that contains the color value indicia, the designation area distinguishing the master calibration page from a local calibration page.
A printing system, comprising:
- a printing;
- a calibration system having a selectable one of:
- a learning mode operable to receive a master calibration page containing color value indicia, and further operable to measure the color value indicia to determine target color values each corresponding to a color value indicia;
- and
- a normal mode operable to calibrate the print unit according to one or more of the target color values;
- wherein the, master calibration page contains a designation area that initiates the calibration system to select the learning mode.
