Methods and systems for converting imaging data so that grayscale representations are eliminated are described. In accordance with one embodiment, imaging data is represented in a print format. The print format is a format that can be understood and used by a printer that is to print the imaging data. The print format is processed in a manner such that any representations within the print format that would result in a grayscale other than pure black or pure white being printed are modified. Modification of the print format can ensure that only black or white appear on a printed page, without any grayscale values therebetween. In one embodiment, a document conversion service for converting grayscale to either pure black or pure white is provided in a network environment and can be accessed and utilized by users via a network such as the Internet.
