Abstract
Abstract A recording data processor comprises a first bit map memory for storing recording data, a second bit map memory for storing color data representing a reproduction color of the recording data stored in the first bit map memory, for each recording data, and a generation circuit for generating recording data for each color based on the recording data fetched from the first bit map memory and the color data fetched from the second bit map memory.
