We recently printed a job for Wendell Burnette Architects that they had prepared in Illustrator. They had 30×30’s printed and mounted on Infinity Board for a presentation to a potential client. Everyone was blown away by the quality. The colors were vibrant and all of the graphics and text were sharp with smooth lines. It was certainly a true representation of their talent.
For the best results from files prepared in vector-based programs save them as an eps. A flattened tiff will work great too.
