ReadirisTM Pro 12 – User Guide Use a sufficiently thick ballpoint. Black pens yield better results than blue pens. Do not use pencils. Don't stylize too much. Excessively stylized characters increase the risk of OCR errors. Don't open loops which should be closed, don't close loops which should be open. Avoid broken characters. Avoid retracing. Retracing reduces the image quality and clarity of handprinted symbols. Characters that are entirely stricken out will not be recognized.
Chapter 13 – Recognizing handprinted text The horizontal underlining bar does not have to touch the rest of the font form. Tip: when less than optimal results are obtained, use the I.R.I.S. writing form and adapt your writing style. The blank I.R.I.S. writing form serves as a full-page template on which block letters can be filled out correctly and in the right size. The form can be found on the Readiris CD-ROM and in the Readiris installation folder.
