Our marketing firm suggested Benchmark.  As soon as I saw the display panels, I could see why. The photos, even though they were blown up to a huge size, look crisp and clear; the colors are beautiful. Benchmark sent them quickly (they rushed to get them to us in time for an upcoming show) and the response we’ve gotten is extremely positive.  I now will use only Benchmark – their quality is outstanding; their prices are reasonable..and they’re nice to work with!
