Paper Abstract

Colorimetric calibration is the process of producing colorimetrically correct data from a device. For the case of a scanner this would involve the process of converting scanner signals into signals which are related in a known way to some colorimetric standard. In the case of a printer, the process is reversed, the task at hand is to determine the printer signals necessary to produce a desired colorimetric signal. A common way of representing colors is by a three dimensional vector. This may be red, green, blue signals, CIE L*, a*, and b* values, or any one of a number of other coordinate systems. Colorimetric calibration can be viewed as the transformation of data in one 3-D space to data in another 3-D space. I present some research into the problem of visualizing the 3-D data used in the process of calibrating a printer. The visualizations are rendered onto a 2-D display, and include the rendering of 3-D gamuts, and vector spaces, and the ability to move around these 3-D spaces to examine details of the 3-D data set.
