An image rendering system and method use a sum-and-difference error diffusion technique that may be utilized in conjunction with image rendering using more than three colorants, e.g., inks. The colorants may be arbitrary and/or redundant. The sum-and-difference error diffusion technique involves two sets of steps. First, steps for performing specification of a colorant amount are separated from steps for determining colorant placement. Colorant placement is then performed by first summing the total number of colorant requests, including any associated error adjustments, and determining how many units of colorant will be rendered. Second, the adjusted colorant requests are sorted to fulfill the image rendering.
