A screen printing process for providing long-lasting, visually-appealing images on PVC blind slats, through use of a computer hardware and CAD\CAM and computer color-matching software. The process, which is for ink-printing the outer surface of a siliconeless PVC sheet (preferably a blind slat) inside a work room, comprises the following stapes (a) purging the atmosphere of the work room from substantially all airborne silicone particles; (b) heating the slat for a duration and at a temperature level sufficient to fully ink prime the slat outer surfaced (C) oxydizing the primed slat outer surface; (d) screen coating the slat outer surface with an ink, this ink being of the type curable under the action of an electromagnetic radiation; and (e) curing the ink-coated slat by submitting the latter to an electromagnetic radiation at a radiation intensity and duration sufficient to completely set the ink onto the slat outer surface; wherein the ink-coated slat outer surface becomes highly scratch-resistant.
