US Patent:

6378976, Apr 30, 2002

Filed:

Aug 23, 1999

Appl. No.:

09/379077

Inventors:

Gary W. Byers - Vista CA
Shirley Lee - Poway CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 217

US Classification:

347 19, 347 96, 347 98, 250271, 2504581

Abstract:

A method and apparatus for a test pattern used in the alignment of an ink-jet pen which deposits fixer fluid, or other clear ink precursor fluid, or even colored ink fluid, on print media incorporates a colorless chemical marker in the fixer that is either infrared- or ultraviolet-sensitive and can either be observed using IR-sensitive detectors or visually, respectively, upon application of IR (or near-IR) radiation or UV radiation, respectively. Thus, data may be obtained with respect to deviations in a carriage-scan x-axis and a paper scan y-axis. Thus, the teachings of the present invention permit a determination of the extent of misdirected or missing nozzles.

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

C09D 1102

US Classification:

106 3127, 106 3143, 106 3158, 106 316, 106 3175, 106 3186

Abstract:

Ink-jet printer inks wherein kogation reduction is accomplished by the addition of phosphonate additives to the inks. In a preferred embodiment, the following are utilized: sodium salt of amino tri(methylene-phosphonic acid), 1-Hydroxyethylidene-1,1,-diphosphonic acid, diethylene triaminepenta(methylenephosonic acid); and potassium salt form of hexamethylenediamine tetra(methylene phosphonic acid). Although in the examples disclosed herein, the salt form of the phosphonic acids were used, the acid form of the phosphonic acid can also be used provided the pH of the final inks are adjusted to desirable levels. Use of the above listed additives essentially eliminate kogation for the life of the pens, such as those used in Hewlett-Packard Companys thermal inkjet printers.

International Classification:

C09D 1102

US Classification:

106 3158, 106 3143, 106 3175, 106 3186

Abstract:

Ink-jet ink compositions are described comprising at least one organo-phosphonic acid. The ink-jet ink compositions reduce adhesive swell, scale formation and corrosion, and as such lead to improved interactions with the structural materials of ink-jet printer pens.

International Classification:

C09D 1100

US Classification:

106 3148

Abstract:

A specific dye set for formulating yellow, cyan, magenta, and black inks comprises Direct Yellow 132, at least one other yellow dye, Direct Blue 199, a magenta dye comprising a dye having the structure and, optionally, Pacified Reactive Black 31, respectively. The dye set provides excellent ink-jet prints having excellent lightfastness when exposed to office light, excellent imaging onto glossy inkjet media, and large color gamut which substantially encompasses the color space for a silver halide reference print. The aqueous inks each comprise from about 0. 1 to about 5 wt % of at least one dye with the black ink comprising from about 0. 5 to about 5 wt % of at least one colorant; from about 5 to about 20 wt % of at least one organic solvent; 0 to about 1. 5 wt % of at least one component independently selected from the group consisting of surfactants, buffers, biocides, and metal chelators; and the balance water.
