In addition to enabling the same ISO metrics as the object-level target, it can provide for measuring illumination uniformity, spatial distortion and resolution variability over the target's areal coverage. This target is best suited for scanner benchmarking or session-to-session quality control and is compatible with\u003cspan\u003e \u003c\/span\u003eGoldenThread\u003cspan\u003e \u003c\/span\u003esoftware.\u003c\/p\u003e\n\u003cblockquote\u003e\n\u003cul\u003e\n\u003cli\u003eThis target provides a means to measure sampling rate (dpi), resolution, color, tone, noise and color channel misregistration.
