TrafficJet Reduces Solvent Exposure

TrafficJet lowers exposure to hazardous solvents used in sign production.  TrafficJet inks are fine tuned to minimize the use of solvents and are used in a contained system within the printer, drastically reducing the amount of fumes that escape into the air and work environment.

Colorado Department of Transportation (CDOT) Realizes Benefits of Adopting a Digital Print System for Statewide Traffic Sign Production

CDOT first state agency in country to benefit from innovative solution
The Colorado Department of Transportation (CDOT) is no stranger to extreme road conditions, responsible for maintaining more than 184,000 miles of state and county roadways and ensuring the driving safety of its millions of residents and visitors. Part of that charge is the production of traffic signs, which must meet very strict requirements for reflectivity and durability in order to protect the public.

Traditional Screen Printing: Time to Move On
Like many DOTs around the country, CDOT for four decades utilized a traditional screen printing technique to turn out its signs. This process, a labor intensive one that requires a significant amount of time and resources to run successfully, was becoming a hindrance to the agency running at peak efficiency. Each screen requires a unique construction with careful maintenance, and the frequent possibility of damage results in a flawed print of the sign. Furthermore, the screens require toxic chemical exposure by shop staff that can only be disposed of by barrel storage and shipping to a specialized waste management facility. As a facility that houses its entire sign manufacturing operation in house to ensure excellent quality and the ability to immediately troubleshoot, the risk of CDOT employee strain by the chemical exposure was a real consideration. Even proper ventilation will not completely eliminate potential side effects of such as headaches, skin allergies or asthma.

Colorado took note of the statistic by the Federal Highway Administration (FHWA) stating that states spend $174 million annually on traffic sign replacement, and thought, “there has got to be a better way, for both our employees and the state’s taxpayers.”

The Digital Print Innovation
Because CDOT knew transforming its shop with a different printing method would be an investment up front, it conducted an exhaustive study comparing digital printing to traditional print methods of sign fabrication. The findings indicated that digitally-produced traffic sign solutions are more durable and significantly easier to produce that those printed via traditional screen-printed methods. Additionally, due to the efficient nature of the process, using a digital reflective printing solution, Colorado could cut its print duration per sign, outputting in one hour what normally would have taken two days.

CDOT sign shop supervisor Bernard Cole said because of digital printing, “More dollars can be invested in maintaining roads, improving safety and reducing congestion. Digital printing techniques will also reduce the amount of hazardous waste produced in the process by using less ink and cleaning chemicals to produce the signs – protecting our employees.”

Enter Avery Dennison’s TrafficJet ™ Print System. The digital solution is an integrated inkjet printing system that allows CDOT to produce specification-compliant and durable traffic signs. It requires less space, equipment and inventory than traditional methods and is allowing CDOT to meet its goal of doing more with less. The system can nest signs of various types, sizes and colors across the full sheeting width, which results in raw material cost reduction and streamlined operations.

Cole said of the print system, “The digital printer has allowed us to go from ‘a few days’ to ‘instant,’” and has increased CDOT’s capacity and capabilities.”

The digital system is allowing CDOT to get signs out the door faster than ever before and allows for more complex and colorful signs. Unlike the old screen-printing method where multiple colors took a long time to produce and dry because of the layering technique, the traffic sign printer system is producing high-quality, multi-colored signs in one step.

Spreading the Word to Other State Agencies
CDOT, because of the success it’s having with the digital solution, is encouraging other county and state agencies to consider the innovation as well. “CDOT’s actually opening the door to new ideas and improvements for the safety of the traveling public,” said senior sign fabricator Damien Stelter.

“With this type of innovation we believe the ultimate winner will be the driving public, who will have a better functioning transportation system,” said Shailen Bhatt, executive director of CDOT.  “Colorado is continually seeking to not just innovate on behalf of our employees, but also for a better return on the taxpayers’ investment.”
