EB's Bright Future

He continues by explaining that the reasons behind these limitations are also threefold: "Current EB curing units are big, expensive, and not well-suited for inter-station mounting. Since the inks are wet until curing and the EB unit is at the end of the press, the inks must be wet-trapped, ruling out current flexographic processing. And complete curing cannot be achieved if oxygen is present, as oxygen is an effective cure inhibitor."
