Studio SC (Seattle) recently installed and tested prototype signage at Seattle Children’s Hospital for its Building Hope expansion and campus master plan. The signs, fabricated by Image Mill, were tested for legibility, color, consistency, size, cap height, and clarity. Placing these prototypes in a low-traffic area of the hospital allowed the design team and owner to see how the signs looked at full size in the environment, and also gave patient-families an opportunity to experience the new wayfinding program and offer feedback.
