CTP Systems -- Violet Support Isn't Shrinking

"Our N91V violet photopolymer plate can achieve maximum throughput with a 30mW system," points out Agfa's Furman. "Consequently, the additional energy from a 60mW laser does not add any throughput value."

Esko-Graphics' Erikstrup reports similar findings from its testing. "Our PlateDrivers used to operate at 30mW in standard configuration and 42mW in the high-speed configuration," he explains. "Our FreeBeam laser now uses a 60mW laser diode, but we hardly use more than 42mW to expose violet polymer plates. We have experimented with certain plates at 60mW, but have deemed that power unnecessary."
