OCR Tips
Use 300 DPI When You Can
Clean 300 DPI scans usually balance recognition quality and processing time better than low-resolution images.
Choose All Main Languages
For bilingual documents, select both languages so names and short phrases are less likely to be misread.
Review Critical Output
OCR can confuse similar characters such as O and 0, l and 1, or rn and m. Verify important numbers before filing.
