PROCESS INTEGRATION
Keys that "turn" themselves

Q: Is there an automated way to read ink dots and automatically adjust the ink keys?

A: Most prepress RIPs can create a PPF (Print Production Format) file, commonly referred to as a “CIP3 file.” This file, based on the same data used to generate proofs and plates, generates ink-key presets for a press with remote ink control capability. The PPF file must be interpreted by an intermediate application before being sent to the press for presetting the ink keys. The application analyzes ink coverage by color and by ink zone and delivers this information to the press, which in turn calculates the physical ink key openings and automatically applies them to all printing units of the press.
