    Abstract: In an example of recording medium identification method, a digital image of a line or a dot printed on a recording medium with a printer is captured by an image sensor. From the digital image, a microprocessor (operatively connected to the image sensor), digitally measures a width of the line, a diameter of the dot, an area of the dot, or a perimeter of the dot. The microprocessor identifies a type of the recording medium based on the width, the diameter, the area, or the perimeter. In response to the identification of the type of the recording medium, a print setting for the type of the recording medium is selected.

    Abstract: An example of an imaging medium includes a substrate, a color-forming layer on the substrate, and a registration mark. The color-forming layer includes a repeated pattern. A repeat of the pattern includes four adjacent color-forming stripes including a black-forming stripe, a cyan-forming stripe, a magenta-forming stripe, and a yellow-forming stripe, or a grid of four color-forming sections including i) a color-forming section selected from the group consisting of black-forming, cyan-forming, light cyan-forming, yellow-forming, magenta-forming, and light magenta-forming, ii) a cyan-forming section, iii) a magenta-forming section, and iv) a yellow-forming section.

    Abstract: An example of an ink supply includes an ink chamber containing a liquid ink, a salt chamber containing a salt solution, a separator positioned between the liquid ink and the salt solution, and a release mechanism. The separator completely separates the liquid ink from the salt solution prior to the release mechanism being triggered. The release mechanism has a triggered position and a retracted position. The triggered position causes the separator to at least partially open, and enables the liquid ink and the salt solution to be combined to form a mixture.

    Abstract: The present disclosure is drawn to ink compositions including from 30 wt % to 75 wt % water, an organic co-solvent system, from 0.1 wt % to 3 w % nonionic surfactant, and from 3 wt % to 9 wt % pigment that is dispersed by separate polymer dispersant. The organic co-solvent system can include, based on the ink composition content, from 15 wt % to 50 wt % of a first solvent portion of high dielectric constant co-solvent with a dielectric constant greater than 30 ε, and from 2 wt % to 15 wt % of a second solvent portion of low dielectric constant co-solvent with a dielectric constant from 1 ε to 30 ε.

    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.

    Abstract: An ink is disclosed. The ink composition includes an ink vehicle, a colorant, and a fluorosurfactant, wherein the fluorosurfactant is a polymer having the general formula: wherein p is any integer, q is any integer, Z1 and Z2 are each fluorine or any functional group, and R1, R2, R3 are each fluorine, any alkyl group, or any functional group, and wherein R1, R2, R3, Z1, and Z2 are not all fluorine and the fluorosurfactant lowers the surface tension of the ink vehicle. A method for improving a property of an ink is also disclosed.
