<p>The method comprises representing a first tone range by forming a plurality of dots arranged in a grid; representing a second tone range by forming a plurality of dots arranged in a grid, representing a third tone range by forming a plurality of dots arranged in a grid, the dots having a body section and at least one extension extending toward a or respective nearest neighbour(s), the extension(s) narrower in width than the body section of the dots, the body sections of the dots representing the third tone range substantially the same size as the larger dots within the second tone range; and representing a fourth tone range by forming a plurality of dots arranged in a grid, the dots having a body section and at least one extension extending toward a or respective nearest neighbours), the extension(s) greater in width than the extensions) associated with the dots representing the third tone range.</p> |
