I have been involved in printing sales since 1983. Back then, in the color key and chromaline era, proofing customer art was a major pain and time sink for both parties.
Fast forward to today, online proofing has lightened that load somewhat but, there still is the customer online viewing, computer system compatibility,sign off issues and other details to contend with.
Digital Dogma has raised the bar for online proofing and approval in one simple step with their workflow proofing system. It has an easy and clear navigation as well as a simple path to archiving your approval. The first time you use it, you will be instantly comfortable.
I highly recommend their online proofing system for all decision makers in the art approval, documentation and archival process.
From my experience with multiple print suppliers, it is absolutely the best, cutting edge system out there today.
