Abstract
A ROM stores density conversion tables appropriate for a present apparatus to execute recording and standard density conversion tables. As a command is entered on a control panel, a CPU sets the optimum density conversion table in a RAM and again converts image data of 256 levels of gradation for a density adjustment. Resultant image data undergoes false halftone processing in an error diffusion circuit and is transmitted to the present apparatus or a destination recorder. When the record characteristic of the destination recorder is unknown, the standard density conversion table is used, so that no large difference occurs for recording.
