Narrative:

Flight clt-ord. First officer flying. Aircraft departed clt en route to ord. First officer had been flying this trip all month and was familiar with the route. Our clearance was hornet one departure stann right (clt 347 degrees) htm as filed. Takeoff and climb out was normal, first officer proceeded outbnd on the clt 347 degree right as cleared. At 50 DME he turned direct htm. Shortly thereafter center called and asked our heading. I told him 305 degrees. He then asked why we had turned. I turned to the first officer and he said at 50 DME on the departure we turned to the next fix. On closer examination of the fine print, the first officer had misunderstood the departure and so did I. I have since highlighted that trap on my departure plate for future reference. I had flown several times in the past with this particular first officer and I feel he is highly competent. I think I placed too much confidence in his familiarity with the route and should've been checking closer, especially since I had not flown this route in the past.
