    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 ink composition includes colorant, co-solvent system, acid (e.g., oleic, linoleic, undecanoic, dodecanoic, and/or tridecanoic acids), lithium, polymer binder, and water. The co-solvent system is selected from i) from ~9 to ~25 wt% of sulfolane with no other co-solvent, ii) hydroxylated co-solvent, from ~4 to ~16 wt% of sulfolane, and at least 8 wt% of another non-hydroxylated co-solvent; iii) hydroxylated co-solvent, from ~7 to ~16 wt% of sulfolane, and at least 3 wt% of the other non-hydroxylated co-solvent; and iv) a hydroxylated co-solvent and from ~9 wt% to ~16 wt% of sulfolane. When i) or ii) or iv) is used, at least 0.15 wt% acid and at least 200 ppm lithium are included; or when iii) is used, at least 0.25 wt% acid and at least 100 ppm lithium are included; or when iii) is used, at least 0.15 wt% acid and at least 150 ppm lithium are included.

    Abstract: A method of security printing can comprise the steps of printing a transparent ink onto a portion of a coated substrate resulting in printed region and an unprinted region, where the transparent ink is devoid of dyes, pigments, ceramics, metallics, and fluorescents; illuminating both the printed region and the unprinted region of the substrate, where the printed region scatters more light than the unprinted region creating a contrast; and detecting the contrast with a sensor that is sensitive to detecting light scattering differences between the printed region and the unprinted region.
