FastInks-these are inks formulated to match the color palette of a color separation computer program called Fast Films™ created by Scott Fresener and sold by R Jennings Mfg. Fast Films™ is an addition to Adobe Photoshop for printing on darks like black shirts. FastInk is a medium opacity ink that is brightest when printed over an underbase like white. We recommend printing colors right out of the can using a 305 mesh and 230 for the white with 20 micron capillary film. This is the easiest ink made to print. Union Ink has discontinued this line of inks, but we still have some while supplies last at 2004 prices. For those screen printers who do not have Adobe Photoshop and Fast Films™ these inks are still wonderful to use. Most of the colors are the everyday colors. So take advantage of how easy they are to print. Also, these inks can be used with Fast Art which is clip art that includes some of the great designs by top artists using Fast Films™. R Jennings sells Fast Art (currently 8 vols.) For help or to order today by calling 1-800-500-2279!
