Tone Reproduction Curves for half tone reproduction quality are an industry standard metric. Improvement in the printing process relates to accurate reproduction of the electronic image. The metric L* has been used as a psychometric indication of darkness and commericail instrumentation is readily available to enable on line measuriment. ln this case study two pieces of work are brought together including Parameter Design using Xerographic/imaging models for analytical optimization, and hardware experiments to both confirm and extend the models to include real world noises. The measuriment metric L* is modifies to be consistent with linear dynamic optimization. Both of experiment were standard L18's with inner and outer arrays. The model experiments used control factor tolerances to simulate real world noizes and the hardware experiments used two signal factor and compounded noises. Errors in Judgment are discussed in the model experiment where sliding scale created unwanted interactions that made analysis more difficult. Verification experiments are summarized for both experimens and improvement to benchmark for an expanded customer usage mode are shown.
