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.
