The invention relates to a color printing device, whereby the color printing device comprises a reciprocating color measurement device and a reciprocating optical density sensor, to a mobile carriage comprising a color printhead, a color measurement device and an optical density sensor and to a color measurement method comprising the following steps: identify the position of a pattern on a two-dimensional media using a mobile optical density sensor; derive the position of a color patch on the media from the position of the pattern; measure the color of the color patch using a color measurement device.

A system for generating digital swatch books, comprising a simulation component for generating, based on a set of standard reference colors and based on at least one reproduction system profile representing a reproduction system's color reproduction characteristics, digital swatch book information representing a simulated set of reference colors associated with the original set of reference colors, as reproduced by the reproduction system; the system further comprising a portable document format generation component for generating, from said digital swatch book information, a multi-layer portable document format file comprising a first layer encoding first swatch book output information for viewing the digital swatch book on a display device, and a second layer encoding second swatch book output information for printing the digital swatch book on a printing device.

One single-stage proofer RIP replaces a conventional setup of two proofer RIP stages in series. Preliminary profile and data processing usually performed at the first of the conventional RIP stages, and source input terminal of the second, are instead performed in a preprocessor at the image-originating or production-hardcopy-printer station. The preprocessor combines production-printer forward and inverse profiles with a profile for the monitor, associated computer or graphics program&#x2014;to form a single profile that converts monitor signals to perceptual data representing appearance of the predicted production copy. This three-way composite profile is applied to the source terminal of the single-stage proofer RIP.
