Abstract
A method of printing with phase change ink on an ink jet printer that contains multiple levels of black gray scale ink and a clear or slightly tinted wax ink base and which is applied to the roughened surface of an adhesion promoting coating applied to a transparent substrate is disclosed. The adhesion promoting coating has a surface roughness of greater than about 0.5 micrometers and contains a binder and an inorganic particulate material.
Claims11
A method of printing employing a phase change ink in an ink jet printer, the printer having a print head within multiple orifices through which ink drops are ejected onto a roughened receiving surface of an adhesion promoting coating applied over a transparent substrate to form imaged areas and non-imaged areas, the ink drops having multiple levels of black, the method of comprising the steps of:
- a) forming at least one imaged area on the roughened receiving surface with the ink drops having multiple levels of black ranging from a lightest level of black to a darkest level of black, the imaged area being bordered by non-imaged areas;
- b) covering the non-imaged areas with a clear or slightly tinted wax ink base by applying clear or slightly tinted ink drops in the non-imaged areas adjacent the imaged areas to prevent the scattering of light transmitted through the adhesion promoting coating and the transparent substrate;
- and
- c) fusing the imaged area and the non-imaged areas to the roughened receiving surface.
A transparency for use in medical diagnostic imaging applications, comprising in combination:
- a) a transparent substrate;
- b) an adhesion promoting coating applied to the transparent substrate, the coating having a exposed roughened surface with a root mean square surface roughness of greater than about 0.5 micrometers;
- and
- c) imaged and non-imaged areas formed by ink jetted phase change ink onto the exposed roughened surface of the adhesion promoting coating, the imaged areas being formed from a plurality of gray scale levels of black ink and the non-imaged areas being coated with a clear or slightly tinted wax base on top of the adhesion promoting coating.
