Abstract
Fundamental machine functions such as the Tone Reproduction Curve need to be divided into regions of smaller units so that each unit can be interrelated to some aspects of the internal machine process. A first step toward that is by decomposing measured TRC in terms of what are known as 'orthogonal basis functions'. Two significant applications for orthogonal basis functions may be extensive use in color controls to maintain color consistency for every page, every time and all the time. The use of basis functions might also lead to a new soft sensor for use in certain machines.
