• I am looking to automatically remove punch holes from scanned documents (preferably from PDF, although I will consider other options).
  I have thousands of pages of scanned documents that all have punch holes in. I know about the Acrobat redact tool, however this is too time consuming to use. I am looking for an automatic solution. The holes are often in different places, so a basic crop won't work.

Solution

It is a common problem when there are marks on the scanned images from the holes created by a hole puncher.

Removing the black marks has to be done manually for each page, by opening the image and erasing the black dots from the image. This process is slow and highly inefficient.

Our program has "Remove Punch Holes" function which automatically detects the location of punch holes on the image and removes them.

The function works for most common hole punch standards.

On the "Tools" menu, click "Remove Punch Holes".

The "Location" parameter allows you to specify the possible location of the holes.
If you are not sure about the exact location, then select all the items.
If you know the exact location, select only this item. This will speed up image processing.

The "Fill Color" defines the new color with which the holes will be filled.
Choose "White" if your pages are white.
Choose "Auto" if your pages are color or gray. The program will automatically detect the fill color.

The following example shows the result of the "Remove Punch Holes" function:
