I'd rather use Photoshop for such a task, perhaps Illustrator.
I've done signs for cutting in ID, but I don't think it has any advantage over Illustrator.
I like Illustrator for that kind of stuff mainly because of the ease of scaling. It also depends on how the finished logos are coming in.
I use InDesign for just about everything. Better type control than PS or AI, export to PDF. Open in AI or PS if the printer prefers one of those formats.
Thanks for the replies, as I read them I gather that it seems to be largely a personal choice, assuming that both modules are more than capable, people prefer the one they know best
Illustrator has more vector capabilities.
Photoshop has more raster capabilities.
Both can have either.
InDesign has fewer capabilities than either - but can handle both vector and raster placed files. It can create vector objects at a simple level.
It really depends on the job - I wouldn't put one over the other - just whichever is better handling the particular job.
And of course the user level - if you can get by using InDesign then use it. Nothing wrong with it. But most print sign shops use Corel Draw/Illustrator and only accept .eps files - which is a throwback to yesteryear, guess they don't need to upgrade their equipment/workflow that much.
With this, InDesign eps output is not fantastic. And opening that in Illustrator can be a hot mess.
Some sign printers take in PDFs or other file formats - you'd have to check with them.
But if you sent them an indd file they might look at you as if you have 10 heads!
Send them a photoshop file? They might not know what to do with it! Or they may not be able to use it!
The best bet is to use the Industry standard for Signage, that would be Illustrator.
But InDesign can handle it - but some printers may not like seeing pdfs or Indesign files or have trouble using an indesign eps.
I'd recommend Illustrator. It's more of an industry standard for such work. If you're producing vinyl signs from customer files, you're probably in for a lot of fix-up work, and you'll likely benefit from owning and learning all three programs.
Personally, I probably use InDesign the most for signs, but that's because I'm more comfortable with its type handling, and the chances are, I already have elements of the sign in existing ID files for the client.
