What jhill said except CMX export works just fine with Omega. It sounds to me like you need to get more familiar with vinyl and foil assignments in Composer. Depending on your background with things like Illustrator, CorelDRAW, screen printing and digital printing, the learning curve for Omega Composer and Edge printing can be anywhere from a couple of weeks to a year or more.
There's a traveling roadshow that Gerber puts on advertised at the top of the page here that would help you some but the first seminar anywhere near you is in the Spring. In the meantime,
here's a link to what's offered at the Gerber website.
With regard to Edge printing, the main features to master in Composer are:
- Spot colors vs. process colors.
- Vector attribute assignments: Cut only, print only, print and cut.
- Handling images.
The secondary features to master are:
- Halftones and LPI
- Choke and Spread
- Bleeds
- Overprints
There are lots of details to each and lots of other features, but if you focus on those things you'll be off to a good start.
Hot Tip!!! The 1234 dialog in Composer is your friend.
