Understanding Scanning Resolution (DPI)

If you are creating a form template or processing forms, it is important to use image file resolutions that support your form's data objectives best. If your image resolution is below our recommended settings for specific types of regions, the lower resolution may decrease recognition accuracy.

The recommended scanning resolution to use varies depending on the types of information you intend to capture from your paper forms. Scanning Resolution is displayed as DPI.

Recommended minimum resolution settings are:
   - 200 DPI for forms using OMR regions
   - 300 DPI for forms using barcode, OCR and Image Clip regions

Keep in mind these other settings as well: If you are scanning forms to a file (not directly into Remark) we recommend using the TIF format, as it is a native image format and processes more quickly than other formats, such as PDF. Tests should always be scanned in black and white (not grayscale or color).
