Zusammenfassung:	Oral solid dosage forms having holographic markings or identification marks such as a watermark thereon and methods of preparing the same are disclosed. One preferred method of applying an identification mark on a pharmaceutical dosage form described herein includes applying a film coating having a first color to an oral solid dosage form such as a tabet and thereafter applying an identification mark to the film coated oral solid dosage form using an ink which not only contains a pearlescent pigment therein but also has a second color which is substantially similar in color to the first color used for film coating.
