In this paper, we list a number of factors that are impo-tant in achieving high recognition accuracy in OCR systems for Telugu and other Indian scripts. While it is relatively easy to obtain 85% - 93% accuracy, it becomes increasingly difficult to improve the performance further. We di-cuss how the factors presented in this paper helped achieve an accuracy of nearly 97% with our OCR system for Telugu script. It is expected that these factors are specific not only to Telugu but also work for other Indian scripts in general and south Indian scripts in particular.
