The mark consists of the stylized letters "D" and "E" and a circular design representing a drafting alignment registration mark. The letter "E" in blue is rotated about 10 degrees from the vertical, and appears in the center of the letter "D" in a hemispherical white space which is attached to a vertical blue line. This in turn is surrounded by offsetting blue semi-circular bands. On the left side, there is a gradient from blue to white. On the lower right, four thin blue lines 90 degrees apart, representing a graphical registration point, are rotated slightly to line up with the letters. A horizontal blue line appears on both the left and right sides of the mark and a vertical dotted line appears on the top and bottom of the mark.
