A card for testing print heads includes a first layer having a first height and longitudinal length and a second layer located on top of the first layer having a second height and longitudinal length smaller than the first length. Also, a method of determining ink drop velocity including providing such a card, and printing a line including a plurality of dots thereon. A first of the dots is located on the first layer and a second of the dots is located on the second layer. Finally, the method includes determining a first relative distance between the first and second of the dots along the print direction, determining a second relative distance between the top surfaces of the first and second layers, and calculating the ink drop velocity as follows: V*(RD/RD), wherein V is the print velocity, Dis the first relative distance, and Dis the second relative distance.
