  • be crisp and clear – no broken/fractured characters;
  • be high resolution images, originally scanned at 600 Dots Per Inch (DPI);
  • be black and white (binary) only;
  • not contain background smudges, colors, or patterns;

In order for InftyReader to successfully process images, the images of characters/math symbols must be crisp, clear, binary (black and white only), non-pixelated, and originally scanned at 600DPI. You can check all of these characteristics by magnifying your PDF document, or image file, to 800%. The characters/math symbols must be this clear and crisp:

Notes:

  • InftyReader will eliminate “noise” (smudges, pencil marks, some highlights, etc.) so long as the “noise” is minor and does not cover any of the text being scanned.
  • Web-based PDF files often contain low resolution images (150-200 DPI) in order to reduce download/load times. In such cases, the recognition results will be useless.
