Configure Scanner Settings

For best results, have your suppliers send native text-based PDF invoices originally generated by a computer. Native PDF invoices allow IDR to read the characters exactly as they were originally created, eliminating many recognition errors and resulting in higher accuracy. However, you can also scan paper invoices and email the scanned image-based documents for invoice recognition.

While sending scanned images of paper invoices, follow these specifications to minimize optical character recognition errors.

• Configure the scanners to produce TIFF or PDF documents. For best document quality, use the International Telegraph and Telephone Consultative Committee (CCITT) Group IV compression at 300 DPI.
• If available, configure scanners to use dynamic, or adaptive thresholding to produce high-quality documents when scanning invoices with color or shaded backgrounds.
• Ensure that page size is either Letter (8.5 inches x 11 inches) or A4 (8.3 inches x 11.7 inches). Larger size pages could cause performance issues.
• When possible, scan the document in the correct orientation. With incorrect orientation, Intelligent Document Recognition tries to automatically rotate and orient the documents correctly.
