Abstract
High resolution ink-jet printing on edible substrates is disclosed in which fat or wax-based edible inks, which contain a colorant, a fat or wax dispersible carrier, and a fat or wax base, are used to produce high resolution images on edibles. The methods utilize a piezoelectric printhead; and the edible products include confectionery pieces having non-planar, hydrophobic surfaces, such as wax-polished sugar shell surfaces, with a printed image thereon having a resolution greater than 100 dpi, preferably greater than 300 dpi.
