OCR (optical character recognition)

The reading of text characters by optical scanners that are coupled with special software that recognizes the characters. OCR inks must be composed of low reflectance pigments, such as carbon black, which can be read by optical scanners. Non-readable inks, though visible to the human eye, cannot be read by OCR readers because they present no reflectance contrast to the machine. OCR inks are available from Graphic Ink Company.
