1. An ink-jet ink for printing on porous, non-porous, and hybrid glossy print media, said ink-jet ink comprising at least one colorant and a vehicle comprising at least one water-miscible organic co-solvent and water, said ink-jet ink further comprising at least three surfactants, the total surfactant concentration ranging from about 0.1 to 5 wt %, a first surfactant consisting essentially of an anionic surfactant, a second surfactant consisting essentially of a non-ionic surfactant, and a third surfactant consisting essentially of a fluorosurfactant, for reducing dry-time, increasing printer/media throughput, and providing good image quality on said glossy print media, wherein said fluoro-surfactant is selected from the group consisting of (RFCH2CH2O)xPO(O
