Two overlapping print layers are visible on a label

If traces of another impression appear beside a batch code, later alteration may be suspected. Examine the label with its packaging rather than a cleaned fragment: overlapping inks, surface damage and adhesive placement can provide different evidence about the order of operations.

What needs to be clarified

Establish the nature of overlapping images, assess recoverable original characters, and determine whether surviving features support the relative sequence of printing and surface changes on the label.

Materials to prepare

Packaging with the label neither cleaned nor detached
Photographs of the marking before opening
Comparison labels and information on the factory printing process

What to compare

Under magnification and varied lighting, record stroke boundaries, coating breaks, rubbing and image intersections. Compare with reference impressions made by the same printing process where available. Start with non-altering methods; discuss sampling separately because solvent treatment or label removal may destroy informative features.

Possible outcome of the analysis

The result may describe layers, legible fragments and a supported sequence of particular interventions, or explain why surviving features do not permit that sequence to be established.

Limits of the conclusions

Two colours do not prove counterfeiting. Relative sequence establishes neither calendar date nor actor; photographs without the original usually restrict examination of overlaps and label material.
