A 3-level dot-pattern method (the 3-L method) has been developed in order to achieve stable and many gradational-level thermal printing with minimal loss in print resolution. This 3-L method employs dot-pattern matrices which consist of three density level dots; black (saturation density of thermal paper), gray (half-black density), and white (paper brightness) dots. The matrices are assigned to picture elements of continuous tone images according to their gradational levels.
