The properties of conventional, ordered dot-pattern generation techniques for bi-level halftone representation are examined and compared with the properties of error-diffusion based, disordered dotpattern generation algorithms. The various processing steps necessary for the adaptation of the disordered halftone pattern-generation technique to digital image hardcopy reproduction with non-ideal computer- output printing devices are described. It includes procedures for spatial distribution of thresholding errors, suppression of dot-density artifacts and compensation for dot overlap. These procedures represent the core of the Multiple-Error Correction Computation Algorithm (MECCA), the objective of which is to linearize the non-ideal printing process to minimize the loss or shift of tonal gradations
