A system and method to accurately digitally simulate a rendering of a printed articulation, stroke or mark by a donor medium used in graphic arts, such as paints, pencils, erasers or other implements. Using a computer (1) or other hardware the system and method provides a digital representation of dye-concentration color mixing, receptor grain and variable grain penetration, and a smooth continuous brush stroke without visible artifacts on a color monitor (6). Other objects of the invention include methods for varying the shape of a tip of an implement (5) across a stroke over a tablet (4) to accurately simulate brushes and other donor-receptor articulation common to natural media, and for rendering a brush stroke in multiple strokes to accurately simulate brush bristles. |
