Punch Hole Removal
Plustek eScan's advanced setting allows you to configure to automatically remove the punch holes from the scanned document images. Documents that are on file usually have punch holes for easier binding purpose. When scanning these type of files, the scanner will detect the hole leaving black dot over places where the punch hole is in place on the digitalize document.
Traditionally removing the black marks, punch holes, on digital documents was done manually, one page at a time. One would need to open the image and erase each black spot manually. A dreaded tedious process definitely not suitable in today's fast pace world.
