ATLAS CLARUS TRACE

BEFORE / AFTER Compare

CONTROLLED SYNTHETIC TEST · QC: NOT_MEASURED

The AFTER image contains a small, deterministic digital perturbation. It is not a print simulation and the signature is not a measured print spectrum.

NOT_MEASURED

ATLAS Clarus Trace compares documented reference and observed reproduction. Physical measurement remains the authority for measured print quality.
