Device Level Targets

In addition to enabling the same ISO metrics as the object-level target, object level targets can provide for measuring illumination uniformity, spatial distortion, and resolution variability over the target’s areal coverage.

All targets are annotated with their L*a*b* values so, if in the future, doubt arises about the color genealogy of the object, and the target is included in the image, the user has a clear path back to the colors and tones of the original object

ISA Targets are designed to:

• Comply with accepted industry standards

• Use Munsell color patches for highest accuracy and consistency

• Require minimal operator involvement for analysis

• Integrate the most comprehensive tests available
