Abstract
The present disclosure relates to a fast drying solvent-based inkjet ink composition for thermal inkjet printing, the ink composition comprising at least 40 weight percent base solvent, a solvent-compatible colorant, not more than 25 weight percent propellant, a decap controlling additive, and not more than 5 weight percent water. The present disclosure also relates to the method and system for inkjet printing with the above-described ink.
Claims17
A fast drying solvent-based inkjet ink composition for inkjet printing, the ink composition comprising at least 40 weight percent base solvent, a solvent-compatible colorant, propellant, a decap-controlling additive, and not more than 5 weight percent water;
- wherein the propellant is compatible with inkjet printhead materials at 25 weight percent or less.
A method of printing a fast-drying solvent-based inkjet ink with an ink composition comprising at least 40 weight percent base solvent, a solvent-compatible colorant, at most 25 weight percent propellant, a decap-controlling additive, and not more than 5 weight percent water;
- the method comprising the step of activating an inkjet printhead to eject the inkjet ink.
A system for inkjet printing, and fast drying of an image on non-absorbent media, the system comprising:
- at least one drop on demand inkjet printhead having a fluid ejector configured for dropwise ejecting ink drops onto a non-absorbant media, the printhead fluidically coupled with an ink source, wherein the ink source includes:
- an ink composition comprising at least 40 weight percent base solvent, a solvent-compatible colorant, at most 25 weight percent propellant, a decap additive, and not more than 5 weight percent water;
- and
- a drying system attached to the system for inkjet printing.
