CGS Oris Real Substrate Proof

A fully colour-accurate digital proofing system for packaging, says Simon Eccles
How does it work?
There are two main elements to the system,
software and printer-ink combination. The
Flex Pack software handles the simulation
of print processes and also rips and drives
the printer. CGS says this includes iterative
4D colour management and spot colour
management, with the ability to simulate
flexo, gravure or other analogue and digital
processes.
It’s Windows based and doesn’t need a
high-power server. It can be accessed
remotely by any web browser with permis-

known Latex inks, and likewise is
