Method and apparatus for economically storing page data for reproduction by a high quality, color, gray-scale printer. A relatively large color value memory is used to store 24-bit color values for the entire page as they are received from the incoming data. The addresses of the color values are also stored in a pixel cell memory along with data which represents the sharpness or exact position of every pixel used to represent text/graphics images. A fixed number of memory bytes are used in the pixel cell memory to store both the sharpness data and the color value addresses for the multi-pixel area corresponding to the fixed number of bytes. In the event the large color memory becomes full of color values before the entire page has been stored, color values in a default memory are selected and addressed by the data stored in the cell memory. The default memory is much smaller than the main color memory. Additional processing can be used to reduce the number of color values needed to be stored in the color memory.
