A method and apparatus are provided for capturing paper-based information on a mobile computing device. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates, crystalline silica, andor formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. The releasable modular interconnect may also include at least one conductive interconnect member affixed to the substrate, where the conductive interconnect member includes at least a one conductive releasable contact disposed within a releasable contact region of the substrate. The first closing element forms a flat seat and the second closing element a ball seat and the closing elements are opened andor closed via a tappet rod.
