Two-Dimensional Impression

Definition

Recorded pattern produced mainly by material deposition, removal or related surface transfer. Suitability depends on which useful features the applied examination can assess. An unsuitable conclusion is task-specific, not proof that the item contains no information for any purpose.

Context
Impression evidence
