Abstract: A method of printing with phase change ink on an ink jet printer that contains ink dots in an imaged area by placing clear or the lightest level of color ink dros in non-imaged areas adjacent the ink drops in the imaged area is disclosed. The method reduces dot gain in phase change ink drops when the image is fused. The method is especially useful for grey scale printing applications in direct or offset printing.

Abstract: A gray scale ink jet printing method and apparatus which produce a high quality images having varying color intensities are disclosed. This is achieved by using a clear phase change ink base and a plurality of colored phase change inks with varying amounts of black dye, thereby producing multiple gray scale levels of black in images with substantial contrast between the imaged and non-imaged areas that are used in medical diagnostic imaging applications.

Abstract: A printing technique wherein pixel locations that are requested to be marked with only black are identified, black is applied to the identified pixel locations, non-black color is applied to a subset of the identified pixel locations that have an associated black half-tone threshold level that is darker than a predetermined non-white threshold level, such that only black is applied to identified pixel locations having an associated black half-tone threshold level that is lighter than or equal to the predetermined non-white threshold level .

Abstract: A method of printing with phase change ink on an ink jet printer that contains ink dots in an imaged area by placing clear or the lightest level of color ink dros in non-imaged areas adjacent the ink drops in the imaged area is disclosed. The method reduces dot gain in phase change ink drops when the image is fused. The method is especially useful for grey scale printing applications in direct or offset printing.

Abstract: A printing technique wherein pixel locations that are requested to be marked with only black are identified, black is applied to the identified pixel locations, and non-black color is applied to a subset of the identified pixe l locations that correspond to on-pixels of a reference pattern of non-black color pixels having an on-pixel population of at least 20 percent and a toner transfer efficiency of less than about 20 percent.

Abstract: A method of modifying a single color bi level bitmap including selecting a marked pixel, determining whether the selected marked pixel is in a half-toned uniform region, marking a first unmarked pixel of a first sequence of potential destination pixel locations if the selected marked pixel is in a half-toned uniform region, marking a first unmarked pixel of a second sequence of potential destination pixel locations if the selected marked pixel is not in a half-toned uniform region, and wherein the second sequence of potential destination pixel locations is different from the first sequence of potential destination pixel locations.
