Abstract
A dot signal conversion method includes the steps of reading a color original for color separation by an image input device and converting the thus formed density signals of respective colors into equivalent neutral density signals and then into dot signals. The dot signals are then fed into an image output device wherein wedges of respective colors are prepared. Dot signal generating tables are then prepared from the relationship between the visual density and dot percentage of each wedge in record and the equivalent neutral density signals are color-processed according to a predetermined formula and then converted into the dot signals by using the dot signal generating tables of respective colors.
