Each ES installation will have different features, depending on the license installed: online approval, prepress workflow, project tracking, imposition management...

ES is a collaborative digital asset production and management platform, offering services ranging from online approval to web-based production environment for all participants of the production cycle, including brand owners, agencies, publishers, pre-media, printers and multichannel service provider. ES lets users plan, execute and control any aspect of media production, regardless of the final use of the output (print, web, ebook, movie, and others). It ensures productivity and longterm profitability.
