Optical security document and method for producing same
By employing microstructure designs with different volume ratios and setting ink layers in optical anti-counterfeiting documents, combined with the precise preservation of the initial reflective layer and protective layer, the shortcomings of existing optical anti-counterfeiting documents in terms of appearance and anti-counterfeiting effect are solved, achieving high-precision and high-color-ratio anti-counterfeiting features and enhancing the anti-counterfeiting effect.

AI Technical Summary
Existing optical anti-counterfeiting documents have shortcomings in terms of appearance and anti-counterfeiting effect. In particular, the anti-counterfeiting features formed by partially removing the reflective layer are simple and it is difficult to achieve both high precision and high color saturation optical anti-counterfeiting effects.
In the preparation of optical anti-counterfeiting documents, a microstructure design with different specific volumes is adopted to form a first region and a second region. An ink layer is set on a portion of the second region. Combined with the precise retention of the initial reflective layer and the protective layer, a high-precision and high-color anti-counterfeiting feature is formed by removing the reflective layer of the second region.
This technology enables optical anti-counterfeiting documents to form diverse optical anti-counterfeiting features in different areas, improving both appearance and anti-counterfeiting effectiveness, avoiding additional processes and steps, and enhancing the difficulty of counterfeiting.
