Apogee PDF RIP works with AGFA equipment via APIS protocol, but Palladio, as OEM Screen machine uses another one, like PELBOX, and (as I still remember), Palladoios imaged via AGFA Grafixx RIP, which actually Harlequin based.
May be latest models of Palladio have APIS, but AGFA laid me off before I was able to touch them.
If that's true, so you have a problem with interface board.
