1. A method for writing a halftone dot having a variable density dot edge profile and associated writing locations and for use with methods that represent a boundary of the halftone dot with an envelope of multiple geometric elements, comprising the steps of: a) associating density values with the geometric elements as a function of the writing locations; b) determining a minimum of the associated density values at one of the writing locations; c) performing a writing with the minimum of the associated density values at the one of the writing locations; and d) repeating steps a) through c) for each remaining ones of the writing locations associated with the halftone dot.
