OCR

The most common use is for simple document scanning – converting printed text documents into editable and searchable text documents. Increasing use of optical character recognition (OCR) systems has been seen in the sector of retail, government, transport & logistics, healthcare, accounting, insurance, finance, IT & telecom, manufacturing, and others.

According to TMR, the optical character recognition market was valued at US$ 70 million in 2019 and had a volume of 15,457 thousand units. It is predicted to grow at a CAGR of 15% from 2020 to 2030.

In general, 300 dpi will be a good resolution for OCR accuracy. 400 dpi may be better for a very small print.
