Hi all,
first thanks for your kind replies and advices. The doubt was to achieve Fogra Standards with a toner machine (Versant 80).
Reading your opinions I understand that you all agree on the fact between inkjet and toner based, the best way to have a certified contract proof it's always on a inkjet printer.
That's very important because it is the first clear answer that I have.
It also confirm my doubts on toner based machines.
Thanks a lot to all!!!
