Abstract
The present invention is drawn to ink-jet ink compositions, methods, and systems for reducing satellite spotting around a printed image. Specifically, an aqueous ink-jet ink composition exhibiting a reduction in aerosol formation during printing, comprises an effective amount of an ink vehicle; an effective amount of at least one ink colorant; and from 5 to 200 ppm of a high molecular weight polysaccharide.
Claims20
An aqueous ink-jet ink composition exhibiting a reduction in aerosol formation during printing, comprising:
- a) an effective amount of an ink vehicle;
- b) an effective amount of at least one ink colorant;
- and
- c) from 5 to 200 ppm by weight of a high molecular weight polysaccharide.
A method of printing an image on a substrate with reduced satellite spotting around the image on the substrate, comprising:
- a) providing an inkjet ink composition, comprising:
- (i) an effective amount of an ink vehicle;
- and,
- (ii) an effective amount of an ink colorant;
- and,
- (iii) from 5 to 200 ppm by weight of a high molecular weight polysaccharide;
- and
- b) jetting said ink-jet ink composition from an inkjet pen, wherein aerosol formation of the inkjet ink composition is substantially reduced resulting in a substantial reduction is satellite spotting around the image.
A system for producing ink-jet ink images having reduced satellite spotting, comprising:
- a) an ink-jet ink composition comprising:
- (i) an effective amount of an ink vehicle,
- (ii) an effective amount of at least one ink colorant, and
- (iii) from 5 to 200 ppm by weight of a high molecular weight polysaccharide;
- and
- b) an ink-jet pen containing said ink-jet ink composition, said ink-jet pen configured to jet said ink-jet ink composition onto a substrate.
