If you had the choice. Would you get Nexus Total RIP or Odystar?
Do you currently have Nexus RIP now?
Ill try to make it simple.
Odystar is a pure PDF workflow that is superior in automation. Has a routing gateway that allows for conditional automation (ie. if page size is this, do this. etc...) Odystar also has a RIP gateway.
Nexus was traditionally a Multi format rip that could drive most any devices. Now nexus has the "total PDF". The total PDF consist of many of the gateways from Odystar to increase nexus's automation as well as versatility. With the Total PDF you also get the PDF Rip Module.
Both the Nexus PDF RIP and the Odystar PDF RIP use the same algorithm's. Hence the rips are identical.
some factors to consider.
1. Cost of Learning? Are your operators familiar with Nexus? Total PDF would require little training.
2. Leverage your current investment. You already own nexus, then it is cheaper to upgrade then switch to Odystar
3. Auto imposition? This is a feature available on Odystar not nexus
4. PC or Mac? Odystar can only run on a mac server. Nexus can run on PC
Hope this helps
