This past summer, massive swatches of color could be found covering a portion of Downtown Chicago, as the intersection and surrounding buildings at Adams and State Streets were decorated with a bright plethora of reds, greens, and blues. This vinyl display was all part of “Color Jam,” the city’s biggest large-scale public art project...ever.

Color Jam was designed by well-known, local multimedia artist Jessica Stockholder as a way of showing “the imposition of colors interacting with the elements and daily chaos of a bustling city.” But not only was this artistic project a unique way of enhancing the city of Chicago and attracting visitors, it was also a colorful example of how to solve vinyl production and installation quandaries.

The Beginning

Earlier this year, the Chicago Loop Alliance (CLA), a business-supported organization, was put in charge of making this project a reality.

After interviewing a few firms across the country, CLA Program Manager and Curator Tristan Hummel recognized that Bloomingdale Signs By Tomorrow in nearby Bloomingdale, Illinois, had the know-how and capabilities to handle every aspect of this project in-house, so he hired them this past March. (Note: The sign shop had already created large-scale vinyl images for the Vancouver Olympics, as well as other high-profile graphics projects.)

After the CLA agreed on a proposal that took him six weeks to draw up, Gary R. Schellerer, president/CEO of Bloomingdale Signs, brought along Director of Operations Alan Schellerer and Installation Manager Patrick Perralt to the contract signing to discuss further ideas. “Alan really loves Chicago and the arts,” he says, “and Patrick is an excellent motivator.”

The end-result: More than 70,000 square feet of four different vinyl materials was used horizontally, vertically, and diagonally. A foil-backed adhesive film was used for the streets and sidewalks; a perforated vinyl to cover glass surfaces; a vehicle wrap vinyl to conform around traffic lights, light poles, flower pots, etc.; and a banner mesh to enhance the masonry of abandoned buildings, as well as the concrete around a CVS store.

(Note: Stockholder originally intended to cover the entire intersection, but the city had some traffic safety concerns and limited this to applying color to crosswalks only and designing an oval pattern for the center of the intersection.)

Alan Schellerer admits everyone was a bit daunted when first hearing the details and scope of the project. “It was on a very large scale and very much in the public eye but with a limited budget and a tight timeline,” he says. “However at our first meeting, we expressed nothing but confidence in front of the client, while the ideas were being presented to us.”

Since the CLA was working within an already-tight budget, the organization also hired Gary Schellerer as general contractor on this project, where he not only rounded up vendors but also acquired signed release forms from property owners, management companies, and tenants in the area. “Originally they thought they would be printing and installing at multiple locations,” he says, “but since we could do everything ourselves, there was no need for that expense.”

Hummel secured permits and worked with Bloomingdale Signs By Tomorrow to manage all the bond work necessary. Meanwhile Bloomingdale Signs handled all the production, printing, laminating, painting (more on that later), and installing. “In total, we had approximately 180 hours of actual print time,” says Alan Schellerer. “Not only did [Perralt] coordinate the install, but he also oversaw the printing and production work and made sure everything was finished on-time.”

Building and Window Wraps

For the red and green building wraps and glass windows along the intersection, Bloomingdale Signs printed fifteen 54-inch-by-300-foot rolls of Clear Focus^® One Way Vision^™ exterior-mount film using an HP Scitex XLjet 1500 printer. Clear Focus provided the film with a clear PET liner to accommodate the UV technology.

“When Gary mentioned the project to me, I was intrigued by the far-reaching opportunities of ‘colorizing’ an entire intersection in Chicago,” says Debra Liles, market development manager at Clear Focus.

Banners

To create banners that would cascade down the focal Color Jam buildings and give a true three-dimensional look, Bloomingdale Signs By Tomorrow printed ten 16-by-150-foot rolls of 10 oz. Ultraflex UltraMesh Supreme material on its HP Scitex LX1500 wide format printer. With 25 percent air flow-through, this material allows wind to pass through panels without risking any tearing or loosening of the affixed banners.

Perralt and his team used their Miller Weldmaster Extreme 112 to weld sixteen-foot sections together to make five large building banners.

“Since this particular mesh has very small, slit-like holes, the holes don’t infringe much on the graphic/ad space,” says Jaime Giannantonio, marketing manager at UltraFlex, “so they were able to maximize the amount of color and ink on the building façade.”

Ground Level

Bloomingdale Signs also wrapped light poles, flower pots, street signs, awnings, stone pillars, and anything else ground-level that could host colored vinyl.

To do this, Bloomingdale Signs printed thirty rolls of 54-inch-by-150-foot General Formulations (GFI) Automark™ 230-54 conform vinyl paired with GFI’s gloss and matte cast laminate on their HP DesignJet 9000 solvent printer. “This material is generally used to wrap vehicles, but they successfully used it here,” says Mike Clay, president of General Formulations.

According to Alan Schellerer, “Since the conform vinyl would be seen very close up, we refused to have any banding or visual imperfections on it. So even though it took four-and-a-half hours per roll, we made sure it was printed right.”
