Abstract: A method for automatically generating a color separation at a digital press comprises defining a color ink array of n-color inks. A separation model is constructed at the digital press based on parameters of the digital press and ink parameters of each of the n-color inks. The constructed separation model is applied to an input digital file to enable printing an element of the input digital file using the n-color inks.

Abstract: A method is provided for adjusting color output in a digital press. The method comprises providing a digital press including a output color ink array configured to print a first spot color element on a media and including an input color array including a process color subarray and at least one custom color input. The first spot color element is printed on the media from the digital press via a spot color simulation of the at least one custom color input using the output color ink array. The first spot color element is adjusted by modifying, at the digital press, the at least one custom color input without adjusting the process color subarray of the input color array.

Abstract: An ink builder to build an ink for a hard copy device. The ink has at least one property that deteriorates in storage. The ink builder comprises an ink tank and apparatus for building ink in the ink tank from a plurality of components and/or an ink maintaining apparatus arranged to inhibit deterioration of the at least one property of the ink in the ink tank. The ink builder may be used in cooperation with a separate hard copy device to which the ink tank can be transferred. Methods of producing hard copies using such a hard copy device are also disclosed.

Abstract: Various embodiments of an image forming device, programs and methods are provided. In one representative embodiment an image forming device receives a document for printing and prints at least a portion of the document monochromatically or in color. Whether the portion of the document is printed monochromatically or in color is based upon the print mode setting associated with the document and the state of the print mode actuator of the image forming device.

Abstract: Input devices are provided. An exemplary input device for a computer comprises a housing, a position-determining system and a trackball. The position-determining system is mounted to the housing, and is operative to determine movement of the housing and to provide a first output corresponding to the movement of the housing. The trackball is mounted to the housing and is operative to rotate and to provide a second output corresponding to rotation of the trackball. Computer systems and other input devices also are provided.
