Abstract: An apparatus and method for measuring the drying rate of a liquid or liquid film in air or other gaseous media by either: a) measuring changes in the print density of the liquid; b) measuring changes in the dynamic surface tension of the liquid; c) measuring the differential pressure between an inert gas required to displace a sample of the liquid drawn into a capillary tube from a reservoir of the liquid and the pressure required for a bubble of the gas to form in the reservoir; and d) measuring the electrical conductance or resistance of the liquid.

Abstract: The present invention provides a method for producing a low-odor, printed packaging material and the printed packaging material produced thereby. The printed packaging material of the present invention is especially suitable for packaging of substances, such as food, drugs and tobacco, which require low odor from printing inks. In this process, the printed ink is activated by exposure to actinic radiation, such as UV light, before an actinic-radiation curable coating is applied thereto. The exposure of the printed ink to UV light reduces residual solvent content and odor of the packaging material and improves the friction resistance and gloss of the printed images. Furthermore, the exposure of the printed packaging material to UV light provides an additional benefit of reducing microbial count, thereby extending a shelf-life of the packaged substance, such as food and drugs.

Abstract: The present invention provides a liquid printing ink that produces high quality flexographic or gravure printing images that have excellent solvent and abrasion resistance. In addition, the printing ink of the invention has high re-solubility, even after complete drying, upon contact with the liquid vehicle of the same ink, thereby preventing clogging of the printing plate, anilox or gravure cylinders over time. These characteristics of the printing ink are obtained by preparing a hybrid ink in which conventional organic solvent and/or water-based liquid inks are mixed with energy curable monomers and/or oligomers of resins and, optionally, a photoinitiator. After drying the ink, the printed images are exposed to an actinic radiation so that highly cross-linked polymers are formed in the printed images, which become water, chemical and abrasion-resistant.
