Abstract
A solid area and edges are detected from original data to be printed. An arbitrary raster of the solid area is shifted by a unit of dot-to-dot distance corresponding to a resolution having twice the dot density of the resolution of the original data, while preserving the data representing the edges so that the edges remain unchanged. Printing is performed on the basis of the above shifted data. The shifting of the dot data prevents the generation of mist and makes it possible to print a high-quality image at a high speed. Thus, the invention provides a printing method and apparatus capable of forming a high-quality image at a high speed.
