The mark consists of a solid green hexagon outlined in darker shade of green and gray with one of its corners pointing down. Inside the upper section of the hexagon are the capital letters "ETC" with the "E" and "C" in red, and the "T" in brown all outlined in gray. The "T" is larger than the other two letters. Below "ETC" is a solid yellow circle outlined in a darker shade of yellow. Inside the circle are the numbers "10" and "-9." "-9" is written as a superscript of "10," and both numbers are written in black. To the right and left of the yellow circle are gray bars. The bars are outlined in black and reach down diagonally from below the middle of the outside of the circle to near the inside of the lower right and left corners of the hexagon. The gray bars do not touch the edge of the hexagon. Below the yellow circle is a partially covered, solid blue diamond. The diamond is partially covered by the bottom of the yellow circle. The three visible corners of the diamond end near the bottom point and lower right and left corners of the hexagon, but do not touch the edges of the hexagon. Below the hexagon are the words "EPOTECH COMPOSITE" in black. The top half of the "C" in "COMPOSITE" overlaps the bottom of the green hexagon.
