The VDL Security Marking Platform:

The VDL is a compact, computer controlled device that modifies a pulse of laser light to produce a unique pattern that is etched into the product surface.

This pattern can consist of 2D matrix, alpha-numeric and simple bar codes and can be combined with various images such as logos, date/ production codes to form a compound codex.

The resulting codex provides a unique code of unsurpassed strength and novel advantages. Using a 2D matrix with a simple image pattern provides a high density machine readable code with a simple consumer verifiable symbol on each product.

Because the mark is made with laser light, the various mark components can be placed on different areas of the product. For example, a 2D matrix code can be placed on one end of a capsule and a simple image or alpha-numeric can be placed on the opposite dome. This provides an open area on the capsule body for standard regulatory product information.

By using different laser types, different material types can be marked. In addition to gelatin based products; glass, plastic and metals can also be marked reliably with permanent codes.

The VDL System uses a very short pulse of laser light similar to a strobe light used in photography. The light pulse is so fast that it -freezes- the product. Variations in product speed or motion have no effect on the mark quality; whether stopped or moving at high-speed, the mark is the same.

Besides mark quality and consistency, The VDL Systems have excellent process reliability. The laser-based VDL process greatly reduces the mechanical positioning requirements of the product conveyance system. Normal mechanical wear of the transport equipment has no effect on the mark quality.

The marking process does not add any chemicals or change the chemical composition of the product. The primary laser systems used with VDL System have been manufactured for almost 40 years and are currently used by major Pharma manufacturers.
