"We've traditionally focused on the retail interior market, so this job was a departure for us, but we're keen to undertake more work in this sector," said McKenzie Clark managing director Graham Clark.

Clark added that completing the Emirates job was a sign of the success of its expansion strategy embarked on last year with the appointment of a number of former staff from Jupiter Display.

Cores are the main stairwells around the North London Stadium, and the South London-based firm had to carry out careful site analysis and bespoke design to ensure that each of the 40x15m graphics adhered to Arsenal's brand, environment and health & safety requirements.

The firm was commissioned to produce the banners by design consultancy 20:20 and worked with rigging specialist Vertigo on the project.

The project was divided into two sections, one to engineer the steelwork to support the graphics and the second to print and install them.

"The reason for so much thought was that this had to look like part of the stadium, not an afterthought, and the graphics had to be 100% drum-tight," said McKenzie Clark sales director David Snaith.

Each 40x15m panel was made out of five sections to enable it to fit around existing 3D logos. Sections were produced on a European-sourced 350gsm PVC mesh that is 100% recyclable using McKenzie Clark's 3m-wide Durst UV printers.
