Abstract
A dye-based ink includes a dye and a solvent. The dye-based ink has a high print quality on plain paper. The dye-based ink may have a print quality similar to pigment-based inks. This may be particularly relevant for black inks.
Description
Related application
The application is the right of priority of No. the 60/610th, 922, the U.S. Provisional Patent Application submitted on September 17th, 2004 of the part continuation application of No. the 10/400th, 131, the U.S. Patent application submitted on March 25th, 2003 and requiring.
Background
Ink jet printing normally by the responding digital signal with by the pixel-wise depositing droplets to the image recording element to produce the non-impact type method of image.
The printing ink that is used for various ink-jet printers can divide based on dyestuff or based on pigment.Dyestuff is the tinting material that dissolves in the mounting medium.Pigment is for being insoluble in the mounting medium, but can be with the dispersion/suspension of small-particle form, often the stable tinting material by using dispersion agent opposing flocculation and sedimentation.It has been generally acknowledged that based on the printing ink of pigment stable not as printing ink based on dyestuff.In both cases, mounting medium at room temperature can be liquid or solid.Generally the mounting medium of Shi Yonging comprises the mixture and the high boiling organic solvent of water, water and organic cosolvent, for example hydro carbons, ester class, ketone etc.
Common paper is often referred to not for specific end use and the paper of coating or design especially.Common paper is made up of cellulose fiber peacekeeping filler usually.Under many circumstances, filler can make ink flow have anisotropy and very little to wick effect (wicking) influence usually.Yet, when printing ink when cellulosic fibre is advanced and pass through cellulosic fibre, liquid stream is tending towards having directivity, and if dyestuff with reactive site in conjunction with or the mode of evaporating solvent deposit in the direction, this is regarded as wick effect so.Printing ink (wherein dyestuff can be penetrated into paper and/or wick effect takes place) based on dyestuff can produce low optical density(OD) and/or uneven edge.
When on common paper, printing, based on the printing ink of pigment can not take place with based on the identical problem of the printing ink of dyestuff.Formed the printing ink based on pigment that on common paper, can produce high printing quality (PQ).Because having been found that the printing ink based on pigment provides than tradition based on the higher printing quality of the printing ink of dyestuff, so conventional understanding is that the printing ink of high printing quality (being generally black ink) should be based on the printing ink of pigment.By the trade(brand)name HP 56 black ink-jet print cartridges of Hewlett Packard to be used for Deskjet 5550, production number C6656AN sells a kind of such high printing quality based on the printing ink of pigment.
The accompanying drawing summary
Fig. 1 is for comprising the synoptic diagram of the fluid deposition system of fluid supplying media according to an exemplary;
Fig. 2 is the chart of the optical density(OD) that reaches with the printing ink of various preparations; With
Fig. 3 for exemplary printing ink of the present invention based on dyestuff, have high printing quality based on the comparison of the printing ink of pigment and tradition based on the printing quality of the printing ink of dyestuff.
