Software & plugins for digital print shops?

Hi guys,

I run a small digital print shop which does general office copying, printing & binding on our Xerox copiers (presentations, flyers, business cards, booklets, etc..); blueprints on our Canon iPF825 MFP M40; as well as high quality posters and signs on our Canon iPF8400.

Our two main iMacs are running Adobe CC and Office 365. It seems we spend most of our time in Acrobat Pro and InDesign. I think I'm also going to need to purchase Pitstop Pro for pdf font issues and imposition.

(I'll admit I'm new to this space and am learning as I go.)

Are there any other must-have applications or plugins that I should consider?

Thanks,
Joe
