DESTRIPERF

DestriPerf is a pattern which is applied into documents which are laminated or which themselves are applied onto a carrier. DestriPerf weakens the substrate of the document to such extend that the perforated pattern is destroyed beyond repair if a forger tries to delaminate the document or tries to lift the document from its carrier. Such tampering is easily detected as DestriPerf allows reliable authentication. DestriPerf can be applied into passports and driving licenses.
