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 sys-
tem, software and printer-ink combination.
The Flex Pack software handles the simula-
tion 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-

the standard eco solvent type. The multi-
