Abstract: An extender for flexographic and other ink compositions and inks using such extender where potato starch serves as the ink carrier and an emulsion resin. The use of potato starch provides for a readily available, cost effective, substantial and environmentally friendly alternative to petroleum and soy based resins.

Abstract: A method is provided for manufacturing a new class of transparent and fluorescent colorants, such as printing inks suitable for use in process printing or non-process printing. The method includes generally two steps. In one embodiment, first, one or more types of fluorescent nanodots, or nanocrystal fluorophores, are selected for creating an ink of a predefined color. Second, the selected nanodots are combined (e.g., by doping process) with a transparent base ink to create a transparent and fluorescent ink of the predefined color. Due to the wide color variety of nanodots, such transparent and fluorescent printing inks may be produced as primaries in more colors than conventional transparent or fluorescent inks, and further can be selectively combined (i.e., overprinted) to create an unlimited number of secondary and tertiary colors.
