This looks reflective. Are you planning on shooting it? A wedge is usually slange for a step tablet which is contacted.

If you plan on shooting it, it will work well if you plan on doing copy work, but the luminance range of a gray scale is shorter than the average scene. There is a distinction between print Zones and subject Zones. Ten subject Zones has a range of ten stops or 3.0 luminance range. I believe the card is closer to 5 or 6 stops (1.50 to 1.80 reflective density range).
