From the pakready web site.

"The Packaging Prototype Bureau service, which utilises our unique Pakready System means we can produce your designs in full-colour photo-quality on virtually any boarded substrate of your choice (including corrugated and flute).

Whether it's a one-off or short-run for field testing, you're up against a tight deadline or simply want to impress your clients to win more business, our bureau service will give you the competitive edge.

With Pakready you get better, faster and more cost effective packaging prototypes than those you produce with a scalpel"
