Many sign makers use Signlab, Flexi Sign etc, Signlab full cut and print can cost £2400 per copy.
A lot of the time files that Signlab is struggling with, Corel does exactly the same in a flash no problem, more power for a fraction of the cost.
Other issues for Signlab, cropped images, CMYK images can't be clipped and rendered and kept in CMYK, the only real advantages dedicated sign making software like Signlab is automatic kerning for letters like WA and number 1 cap I etc given the space that suits it not the same space a W would have etc which just looks outright odd, see it everywhere, it's horrible, plus all the support for plotters and printers, decent quality fonts too so used at any size no surprises as you can get with system fonts.
Corel is practically there but not quite and they have said if there is enough interest from sign makers they will consider developing the software to suit sign makers needs, and what a day that will be where we can all avoid importing and exporting back and forth and relying on the coding written by a couple of guys in a shed for Cadlink.
Even then all prints done through Signlab and it's Visual Production Manager has a green hue, that was there in version 8 and in Version 9 it's still there, so when they've come to bring out the new version, they still hadn't cracked the previous one and carry the faults into the new build.
So if you would like to see a CorelSign or Corel Draw with built in features to accomodate sign makers, then make yourself known.
Literally the only things CorelDRAW needs to crush every sign specific app on the market is native plotter (vinyl cutting) support. If they threw in a RIP/Cut app then Signlab and Flexisign would cease to exist (and good riddance to both of them).
You should take a look at the ECut plugin. I don't use it for cutting myself since we use flexi, but many of the other features are super useful regardless and it's pretty reasonably priced and updated often.
If curious - ecut is here:
It's a commercial plugin, and very popular at our CorelDRAW-centric site.
