Methods and systems receive a print job and determine whether the print job specifies one or more extended gamut color marking materials. The extended gamut color marking materials comprise marking materials having colorants other than standard colorants. The standard colorants consist of cyan, magenta, yellow, black (CMYK). When the print job does not specify one or more of the extended gamut color marking materials, the methods and systems determine whether the print job will perform better with one or more of the extended gamut colorants in addition to the standard colorants. The methods and systems print the print job use the extended gamut colorant(s) and the standard colorants when the print job specifies the extended gamut color marking material, and when the print job will perform better with one or more of the print system's extended gamut colorants in addition to the standard colorants.

Methods of performing print engine calibration create a color space conversion equation for a scanner of a class of printing devices, print test patches on a sheet, and scan the test patches using a scanner of the printing device to produce a scanned RGB value for each test patch. Such methods convert each scanned RGB value to an XYZ pseudo space using the color space conversion equation to produce XYZ values. These methods compare the XYZ values to second XYZ values of white paper to generate DeltaE curves for each of the test patches relative to white paper. The DeltaE curves are interpolated to form an equivalent aim curve. After the equivalent aim curve is determined, the methods periodically calibrate the same or an additional printing device that is within the class of printing devices using the color space conversion equation to produce second XYZ values.

A method and graphical user interface for selecting pad printing functions for an image output device. The user interface is provided to a user and displays a pad printing dialog box that enables selection of pad printing output. Selectable pad printing options are displayed, which include the number of sheets per pad and the total number of pads to be output. When the user selection of pad printing and pad printing options are received, the total quantity of sheets to be output based on selected pad printing options and organizing the sheets for pad printing output from the image output device are automatically determined. Availability of pad printing is determined based on finishing options selected.
