  1. 1. Why Is it even important?<br />Protect you investment<br />Get the greatest possible ROI<br />Ready for future demands<br />Positioned for scaling<br />Only when you have mastered your solution today should you / can you advance to the next<br />
  2. 2. FIRST! Know your documents<br />Most common question asked all vendors:<br />“How accurate are you” – the un-answerable question<br />It’s not as simple as you think<br />Type of text/handprint<br />Full Page / Data Capture<br />Fixed / Semi-Structured<br />Business process associated with recognition<br />Level of variations<br />Likelihood of new document types<br />What are you willing to give up in exchange for accuracy<br />
  3. 3. Form Design<br />Corner Stones<br />No underlined fields<br />Ideal field types<br />Proper Field spacing<br />Favor simplicity<br />Numbers<br />Separated fields ex. Phone number consists of 3 separate fields<br />
  4. 4. Paper Document Prep<br />Bad prep, Bad!<br />Folds<br />Scan batch size<br />Paper type<br />Tacky paper<br />
  5. 5. Scanning<br />Resolution<br />Bit Depth<br />Black and White, size and accuracy<br />Grayscale: size, accuracy, repurposing<br />Color: accuracy, repurposing, and future demands<br />Scanning feed path<br />72 Dpi 96 Dpi 150 Dpi 200 Dpi 300 Dpi 600 Dpi <br />Greater Accuracy<br />
  6. 6. Digital Document Prep<br />Some image clean-up is good for OCR some isn’t<br />Relative to the document type<br />Border removal<br />Deskew<br />Despekeling<br />Background Removal<br />Character Regeneration<br />Thresholding<br />Dropout<br />
  7. 7.
