Abstract
A look-up table of ink density values corresponding to a predetermined number of printed bit patterns is used to convert a high resolution bi-level data file into a lower resolution contone data file. A method to convert bi-level data to contone data includes reading a specified number of words from the bi-level data and retrieving, for each word, an ink density value from the look-up table using the word as an index into the table.
