  • Fingerprint ink dispensing apparatus
    Patent number: 6298805
    Abstract: A fingerprint ink pad arrangement, for use in taking rolled fingerprints, includes an ink reservoir formed of a porous material positioned against the inner wall of a cup shaped housing with a tubular substantially noncompressible ink dispensing substrate formed, for example, of a ceramic or plastic, positioned adjacent the ink reservoir so that ink flowing from the reservoir travels through the substrate to the fingerprint area.

  • Nonstaining fingerprint ink and applicator therefor
    Patent number: 6027556
    Abstract: A nonstaining fingerprint ink is formulated from one or more alcohol soluble dyes, e.g., Acid Black 5 dye, dissolved in one or more fatty acid esters which have at least one available hydroxyl group, e.g., glycerol monoricinoleate, the dye constituting about 5% of the total ink by weight. An applicator, particularly well suited for the ink, includes a pad made of a melt blown calendared fabric encapsulated in a gas impermeable pouch.

  • Fingerprint ink
    Patent number: 5919292
    Abstract: A fingerprint ink is formulated from a solvent carrier and a low structure carbon dispersion. Carbon particles with an agglomerate size of less than 100 millimicrons are dispersed in a hydrocarbon soluble oleo resin to form the low structure carbon dispersion, with the carbon particles accounting for about 40% to 60% of the total dispersion and the dispersion accounting for 20% or less of the total ink formulation.
