A high quality color priting image compression method is presented. This contains dividing image into nxn blocks, vector-quantizing each block independently. In this stage, quantizing level is decided by means of range statistics. As the result of this method, about 1/10 of compression ratio and about 30dB of S/N raio is achieved.
