Acrobat DC: Enhancing Scanned Page Contents



in this video I'll show you some ways you can improve the quality of a page before capturing text and some considerations to keep in mind as you process your content I'll do the experiments so you don't have to before I start with scanned pages here's a quick tip for making Acrobat work faster for you rather than working from the right-hand pane take a minute and add the tools you need to the quick tools toolbar right-click in the toolbar area and choose customize quick tools open the tools that you're going to work with in this case enhance scans select the tool you need such as the enhance tool click the + up arrow to add the tool to the toolbar click Save to close the dialog here's our new tool ready to use first up I have a terribly crooked page something that can happen when you scan to fix it click enhance scans scan document you'll see the full enhance scans toolbars open click settings the filters section shows the status of the available repair filters with the deskew filter active by default leave it selected and click enhance when you capture the text Acrobat redraws the page on lining the text always leave the deskew culture active the next tool will look at is background removal useful for slightly muddy looking pages but I've got a real test here's a page from a book written in the 1600s the pages are very dark with poor contrast Dork and leave behind the letters I've got one version of my page adjusts it in Photoshop to correct the contrast and another one with the background removed also the background removal – hi and capture the text if I then activate the suspects and click review recognized text you'll see some significant differences in the adult read scan the text capture is surprisingly good although there are quite a few suspects and some unidentified errors the scan from the page with corrected contrast is far better both in terms of suspects and miss errors the black and white scan is useless with virtually every text stream of suspect the takeaway background removal works best when the page has a decent amount of contrast next up let's look at D screening notice on this page that the text is surrounded by little dots which can occur when you scan newsprint in the first example the capture is done without D screen 5 the capture is too bad but let's try with the D screen filter there really isn't any improvement in the capture the screen can't improve this scan although it may work in some cases the final filter sharpen is text here's my starting document in the first example I've captured the content without any sharpening you see the capture is very poor in the second example I'll set the text sharpening to high and try again is not disappointing although the text looks much heavier on the page there's no improvement in the capture the filter may work for some files but you can't enhance a poor scan Oh
