If you do not have an AR Target coaster, you can download a PDF file with a target image from here and print it. Print the target on heavy card stock, if possible. If standard paper is the only option, be sure that it is smooth and flat as possible. For better results, affix the paper target to a firm and flat piece of cardboard or other material. Remember to print to scale (1:1, no scaling) and cut out the Augmented Reality Target from the surrounding page.
