Abstract

The laser marking intaglio plates were printed in intaglio proofing machine. Three halftoning algorithms for multi-grey image were proposed. The printing and scanning proofs were compared with the simulation images of digital halftoning after scanning the proofs. The quality of images was evaluated by halftoning image quality evaluation method based on human visual system. The experiment results showed that the "bright spots" on the spectrogram gradually tend to be evenly distributed and the error decreases more with increasing clustering partition. Halftone noise level can be aptly described by the proposed method. The residual noise change and uniform characteristics of the smooth region were given for the halftoning image edge and detail place. The results provide effective basis for objective description of halftone image quality.
