Cursive or italic fonts, and font sizes less than 8 points Remember that most OCR software cannot recognize handwritten characters. Most part of OCRB is identical to what is defined by. ANSI X3.49-1975 (R1982) describes the nominal shapes, sizes, and printing positions of OCR-B characters. There are 2 font sets the US government accepts for Optical Character Recognition : OCR-A and OCR-B. These documents are challenging for OCR because they use non-standard fonts and suffer from printing noise, artifacts due to aging, varying kerning (space between letters), varying leading (space between lines), frequent line-break hyphenation, and other image problems due to the conversion from print-to-microfiche-to-digital.
