    Abstract: The present disclosure is drawn to a pigment-based inkjet ink and methods. The inkjet ink includes water; from 2 wt % to 9 wt % pigment solids; from 0.05 wt % to 2 wt % of an acetylenic diol non-ionic surfactant; from 0.05 wt % to 2 wt % of a second surfactant. The second surfactant can be a polysorbate having at least 50% lipophilic oleic acid groups and having an HLB value of less than 15, or a C12-C18 polyoxyethylene glycol ether having an ethylene oxide number less than 20, or a perfluoropolyether including a polyethylene glycol primary alcohol or diol. The inkjet ink also includes from 5 wt % to 50 wt % of an organic solvent system comprising triethylene glycol and a cyclic amide.
