For sign work CorelDraw has some distinct advantages over anything else out there.
The three that come to mind right off hand are:
- Node editing is a much saner experience with CorelDraw than it is with Illustrator. Very important if you want smooth cut curves from your plotter.
- When working on large sign projects in Illustrator the maximum artboard size can be frustrating. Not a problem with CorelDraw.
- The ability to work with more than one page in a single file once again sets CorelDraw apart from Illustrator. Sure you can more or less accomplish the same thing in Illustrator using layers but that's a duct tape and haywire work-a-round in my opinion.
All you really need is CorelDraw, CoCut (from Corel) and maybe Caldera for a RIP if that's required. With these three programs you have a tool set that is reasonably priced and feature rich. Really can't ask for much more than that.
