ABSTRACT:
A method of generating a halftone image on a printer from a grey scale image using a dither matrix. The halftone image is represented by symbols when it is printed out by the printer. The matrix includes many patterns. Each pattern has many elements having values with a different number of ones and zeros. The values of the elements in each pattern depend on a model of the symbols. The model is incorporated into the patterns as each pattern is generated.
