Abstract: Non-pigmented, water-based inks are disclosed which are compatible with industrial piezojet printheads and which can be used to form high resolution images on edible substrates, including sugar shell confectionery polished with a hydrophobic wax polish. The ink comprises a hydrolyzable polysaccharide adhesive agent, such as tapioca dextrin or gum arabic, which enhances the compatibility of the ink for hydrophobic surfaces.

Abstract: Method for printing on a pharmaceutical tablet by etching a printing plate to form a pattern of etchings therein within an area corresponding to an outline of the tablet, varying the ink-retaining volumes of the etchings in a pre-determined manner and in a direction across the etching pattern from one side to an opposite side, placing ink into the etchings, and transferring ink from the etchings in the etched printing plate onto an outer surface of the tablet. Variations in the ink-retaining volumes of the etchings cause a larger amount of ink to be transferred from etchings having a larger ink-retaining volume than from etchings having a smaller ink-retaining volume during the ink transfer stage. This causes different changes in the color of the outer surface of the tablet dependent on the amount of ink being transferred.

Abstract: Enteric film coating systems for orally ingestible substrates such as pharmaceutical tablets and dietary supplements are disclosed. In preferred aspects, the enteric film coatings include an ethylcellulose dispersion and a substantially gastro-insoluble pore former such as sodium alginate.

Abstract: Agglomerated starch compositions containing native starch and pre-compacted starch powder is disclosed. The agglomerated starch compositions have superior flow and less pH sensitivity than simple blends of the two components at equivalent ratios.

Abstract: The present invention is directed to film coating systems for use on oral dosage forms such as compressed tablets and orally-ingestible substrates which have improved pearlescent qualities. The film coating systems can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the pearlescent film coating is prepared as a dry powder mixture containing a cellulosic polymer, a detackifier, a gloss enhancer, and a pearlescent pigment. Film coating compositions containing an aqueous suspension of the powder mixtures, methods of applying the coatings to substrates and the coated substrates are also disclosed.
