Prepare a readable scan
Keep pages upright, margins intact and small characters sharp. Blur or compression can change vowel marks and digits.
Multilingual document guidance
Indian language OCR needs careful review
Indian documents often mix regional scripts with English names, numbers and tables. Preserve the original script, compare important fields with the source, and measure accuracy on documents like yours.

Preserve original scripts
Keep each language in its source script. Review mixed English and regional-language lines without silently translating names.
Check critical fields
Compare names, GST identifiers, dates, amounts and table columns against the source. Use a human review step for consequential data.
How to judge accuracy
Build a human-verified sample for each language and document type. Compare text using character error rate, then check exact matches for identifiers and amounts and whether values land in the right table columns. Publish or rely on an accuracy percentage only when it comes from a representative test set.
