When NFT tracking, how close to the camera will the printed image be when in use? This relates to the required resolution, commonly expressed as pixels or dots per inch (DPI). Most laser printers produce 300 dpi black and white images, while color printers usually use a dot-screen at 150 dpi (although they may advertise higher resolutions, almost all use a 150 dpi resolution). To help answer the resolution question, use the “NFT Utilities for ARToolKit” tool supplied with ARToolKit (found under the path: [downloaded ARToolKit SDK root directory]/bin). Once you have determined the maximum resolution required, return to this page.
