Print Style definitions

Has anyone ever tried to create new print styles?

I have tried to do so using page imposition as one of the parameters, but it does not take. Each time I have to set the two-up imposition.

It should be ok as I have set it up in X6 and it works. I compared the prs files and both have the parameter set. The Ventura prs just does not do the job.

Any ideas?
