Store Receipt — Searchable PDF
A realistic café receipt as a searchable PDF with a real text layer — the OCR ground truth paired with an image-only scanned twin, so you can score OCR output against known text.
Store Receipt — Scanned (image-only PDF)
The same café receipt as an image-only 'scan' — no text layer, with a slight rotation and grain so it reads like a photographed receipt. Paired with the searchable version as OCR ground truth.
