Additional options are available on the menu for the sPDF and nPDF text formats. The three image quality settings
are:
•
Minimize Size —smallest file size, lowest image quality.
• Normal —medium file size, some loss of image quality.
• Maximize Quality —largest file size, no loss of image quality.
Note: Documents scanned with nPDF and sPDF automatically include OCR processing. If the processing does not
recognize a large number of the text characters in the document, change the image quality setting and re-scan the
document. For example, change from
Minimize Size to Normal to see if the text recognition improves.
The Use MRC option is a special processing procedure for documents scanned with the PDF format.
• Use MRC —MRC stands for Mixed Raster Content. MRC is an advanced technique for optimizing the image
quality of scanned documents. Without MRC, the scanned image is produced using a single process to capture
and display the image on the computer screen, even if the document contains both text and graphics. With
MRC, the image is produced using separate processes for text, graphics, and other elements on the document
page. The result is clearer graphics and sharper text characters. Scans with Use MRC selected may take slightly
longer to complete the processing. Select
Use MRC for documents with harder-to-read text or lower-quality
graphics to get the best possible scan output image. The Use MRC option is available for sPDF and PDF.
Searchable PDF —the .pdf file format used by Adobe Acrobat. This format converts
scanned text into PDF with an invisible text layer for searching.
Normal PDF —the.pdf file format used by Adobe Acrobat. This format converts scanned
text into a PDF with the text ready for editing in a PDF editing program.
