Abstract
Machine-enabled methods of, and system, and processor readable media, embodiments for, tone quantization error diffusion, comprising a first stage process and a second stage process, where the quantization and error diffusion steps may be completed for lines scanned according to the first stage, and the quantized pixels may be tested to determine the actual output halftone pattern of the pixels. The quantized pixels may be tested to determine their actual output halftone pattern and threshold levels may be determined by measuring dot intensities for the output device, e.g., a multi-functional peripheral device.
