This invention is comprised of printed shaped bodies and sheets comprising gelatin or having at least an outer surface comprised of at least 5% gelatin or chemically modified gelatin, the shaped bodies and sheets being printed with ink by an ink jet. In particular, the ink applied to the shaped bodies and sheets by the ink jet contains an aluminum and/or calcium compound in addition to dyes and/or pigments, or an aluminum and/or calcium dye compound, and optionally non-volatile proportions of solubilizers and/or dispersants. Further, where the ink contains an aluminum compound, the ink is preferably adjusted to alkaline condition. The invention allows shaped bodies or sheets of gelatin to be printed with ink that is unlikely to be transferred in the form of 'ghost images' to adjacent shaped bodies or sheets.
