A security ink is provided containing a colored dye, a colored pigment, and a fluorescent pigment. The ink may be printed on a number of security documents such as checks and may be passed through printing devices such as laser printers without the problem of damage to the ink the printed image, or the printer. The fluorescent pigment in the ink will fluoresce when the document is exposed to ultraviolet light and may be used to provide an authentication feature.
