The desired features of a new camera characterization target are described. Any new target must minimally be justified by meeting or exceeding the characterization performance targets used in current imaging processes. Additionally, a target should be physically robust against normal laboratory handling, including the ability to be cleaned after being soiled. To be less sensitive to illumination and camera geometry, all patches in the target should have identical gloss and more generally the same BRDF characteristics. Finally, some colors should be included that are similar to those in anticipated materials to be imaged. These features will allow a more productive and continuous workflow without interruptions imposed by inadvertent target mishandling, and bring cost and time savings by eliminating unnecessary recalibrations. After describing the process for selecting the colors of such a target, the target camera characterization performance is compared against targets in common use.
