How To Clean Up A Scanned Document In Photoshop
Do you take Adobe Acrobat? Yous cannot do this with the free Reader.
In Acrobat you can select to clean up your certificate either at scan time, or if you have a scanned document already saved equally a PDF, at a afterward time. To clean upwards such an already scanned document, you would select Tools>Certificate Processing>Optimize Scanned Document.
This gives you a number of filters that volition "optimize" your document:
When you click on the Edit push in the "Filters" section, you get the filters dialog, which allows you to straighten ("Deskew") the paradigm, and do a few other things.
Unfortunately, this will very likely not become rid of your hole punch and staple artifacts. For this y'all either demand to encompass upwardly or redact these areas, or use an external image editor for further cleanup. I use Photoshop for this, but it requires that you lot open it for every scanned page. You would select Tools>Content Editing>Edit Text & Images, then correct-click on an image and select to edit information technology in Photoshop. Once you've cleaned upward your prototype, you can and then save the paradigm in Photoshop and information technology will become imported automatically into Acrobat.
Equally I mentioned, another option is to cover up these areas with "whiteout" - you can use the drawing markup tools nether the "Comment" header on the right side to do that. But brand sure that you select white as the edge and the fill color. This volition not permanently modify your certificate, you would still be able to recover your original content (even after flattening such a document). You lot can notwithstanding employ the redaction characteristic in Acrobat Pro to remove these elements in your scanned prototype completely.
