Most flatbed printers come with a dedicated RIP so that anyone with multiple printers will likely have several different RIPs. In theory, color management should ensure that all these printers are capable of producing the same color output but most experts advise that using a single RIP will produce more consistent results.
However, not all RIPs can support multiple printers and you’ll almost certainly have to buy additional licenses or drivers. You will probably need to factor in extra workstations to cope with the additional processing work. Most RIPs can handle ICC profiles through the ability to create and to edit those profiles may be an optional extra.
There’s also a growing number of wide format workflows that can separate the file preparation away from actually running the printer. Some of these, such as Onyx Thrive, have evolved from existing RIPs. But others, such as Agfa Asanti and GMG ProductionSuite have been designed as modular workflows. In either case, the ability to centralize the color management is a major selling point and all of these have facilities to create and manage ICC profiles.
