Abstract
A method of machine control including the recreation of a tone reproduction curve by providing a look up table. The look up table incorporates a covariance matrix of elements containing n tone reproduction samples. A matrix multiplier responds to sensed developed patch samples and to the look up table to reproduce a complete tone reproduction curve. A control reacts to the reproduced tone reproduction curve to adjust machine quality.
