DigiGuard® Plus strengtheners enhance HP-validated UV OPVs’ performance in combination with Michelman’s DigiPrime® priming solutions. This allows press owners to increase addressable market size, better serve high-performance label markets, and produce more with HP Indigo digital label presses.
Expand into high-performance label markets such as personal care & cosmetics, household cleaners, automotive oils & fluids, wine & beer bottles, and industrial & electronic equipment. Choose the precise strengthener, primer, varnish, and substrate to match the needed application.

The primer, ink, and UV varnish layers must interlink to achieve the required performance. HP Indigo ElectroInk permits chemical crosslinking between it and the primer and varnish layers, which allows the strengtheners to provide the needed resistance. Additionally, the strengtheners have been successfully tested on HP Indigo-approved DigiPrime® 680. We recommend testing DigiPrime® 040, 050, and 060, and other HP Indigo-approved in-line primers to confirm performance outcomes.
