Digital Printing and Printer Maintenance: What the Traffic Sign Industry Needs to Know

In many areas of the country, stepping into a traffic sign shop is something done at your own risk. Shops located in small public agencies are often located in the back of the general maintenance shed. Yes, behind the dump trucks, the snow plows and maintenance benches. I know, I’ve visited my share over the past thirty years and have a stack of oil-stained slacks to prove it. Don’t get me wrong - our industry also has a number of impressively organized - and clean - facilities around the country - private and public agency alike. And done right, all are capable of producing long-lasting, quality traffic signs.

And viewed in today’s eyes, our traffic signs have roots in some pretty unsophisticated production equipment. Remember the “one-arm-bandit” squeegee tables and steel-rule dies for cutting Highway Gothic letters for street name signs? The industry has evolved, but we still look at computer-cut overlay film production with wide-modern eyes in the same way that cro-magnon man viewed fire, or the way Mr. Watson expressed surprise at hearing "Mr. Watson - come here - I want to see you" at the other end of Alexander Graham Bell’s first telephone call on March 10, 1876. And all the while forgetting that the commercial graphics industry largely walked away from both forms of production in favor of wide-format digital printing years ago.

In fairness, reflectivity and durability demands of today’s traffic signs coupled with digital ink limitations have largely prevented production methods from evolving sooner. Only recently have advancements in ink and overlay films been achieved that make the production of specification compliant, and durable digitally printed traffic signs a reality. We’re here now, so welcome to the modern era of traffic sign production!
