Abstract:
The method of limiting the final colorant amount of one pixel of one separation of a number of non-black separations, said pixel comprising original colorant amounts, while printing an input color to a color printer comprising the steps of:determining a total value of maximum colorant amount for the number of separations which can be printed by the printer, the total value being the addition of the maximum amounts of toner that can be printed for each separation,determining a smaller value for the amount of colorant for the number of separations which is smaller than the total value to limit the final colorant amount to a pre-set allowed total colorant,determining a total value for the sum of the values of the original colorant amounts in the number of separations,generating a first bitmap for the smaller value divided by the number,generating a second bitmap for the sum of original colorant values divided by the number,using the smaller of the two bitmaps to generate a final bitmap, andprinting the final bit map.
