If you want to work with the text on the page, the closer you are to the example at the right, the better your results. Note: You aren't left totally to your own devices. Acrobat includes a number of filters that can help with some of the contrast and visibility issues, as I'll cover later. In some cases, you won't have perfect results regardless of how much you tweak a scan. Two types of documents are notoriously bad time-wasters: newsprint and low-resolution images.
A halftone image, as you see on a newspaper page, uses a series of ink dots applied at different angles Figure 3, right image. If your scanned page starts from a low-resolution image or if you scan with a low dpi, there's simply not enough data for a reliable conversion to text Figure 3, left image. It's that simple. Figure 3: Not enough data is simply not enough data. If you can't get a different version of the source document to use, you can try to scan the page at a higher resolution, try the Acrobat filters, or open the scanned page in an image-editing program and try to improve the contrast.
A common misconception is that the higher the resolution, the better the scan. That's only true to a certain extent. The best range for scanning a page where you want to capture the text is within the dpi range. Anything below that doesn't offer Acrobat X enough information to translate the image to characters; anything much higher than dpi wastes processor time.
More image data won't produce better output, but may crash your system. By default, Acrobat X downsamples the file to dpi. If you have a basic page of text using about 12 pt. Here's a simple guideline: The smaller the text, the higher the scan resolution.
Scan a page containing text smaller than 10 pt. Tip: On the other hand, if you're scanning a photo or high-quality image and want to use it as an image intended for print output, then the sky's the limit—scan at any resolution your printer can support. The quality of the scan and the file size are proportional. In other words, the smaller the file size, the lower the quality.
You don't need a high-quality and large file size scan if you're just scanning some receipts to submit for reimbursement. The default setting sits about one-quarter of the way from the left of the slider, and works well for basic scanning and OCR. Figure 4: Choose a setting for scan optimization. You'll see adaptive compression settings at the top. These settings apply different types of compression to different types of content on a page. The idea is to decrease the file size without sacrificing the quality of the output.
For the most part, you can leave the default settings as is. Acrobat X applies some filters automatically, while others offer choices. Here are the choices, and when you'd use them:. Well, that's the big question, isn't it? If you need to use the content of your document, then you need to capture the text. A scanned page is simply an image of the text, and can't be searched, indexed or accessed by screen readers or other devices. Acrobat X captures text from any document, whether you're scanning it or have it as an image from another application.
Figure 5: Pick an OCR type. Searchable Image OCR files are generally larger than ClearScan files, but allow you to search for indefinable items, called suspects. To see all the suspect text highlighted on the page, click Find All Suspects in the Recognize Text tools panel. To review each suspect, click Find First Suspect.
In the example shown in Figure 6, you see all suspects highlighted in the page section. Click Find First Suspect to open the Find Element dialog box where you can check and process each suspect. Click Accept and Find to go on through the rest of the page. Figure 6: Evaluate suspect text in the page.
ClearScan technology is fundamentally different from Searchable Image technology. Acrobat X automatically recaptures the content using ClearScan. At the bottom of the Scan dialog boxes, you'll find choices for standards compliance and using metadata:. Tip: If you are creating multiple files, you can enter common metadata for all the files. Good Morning, I am a Pub Tech for a company archives old documents.
My problem is that when I scan the documents, the pages sometimes have staple marks, paper hole images, kinda off color background.
Is there any way to clean up the pages? Thanks Have a Blessed Day,. I just want to scan a lot of service invioces 80K and then be able to referance them by one number in the upper right hand corner. Thanks a lot from Sweden. There are several tutorials that describe how to do that. PDF from scanner This was easier in previous versions of Acrobat Pro, as I remember.
There is I hope a simple solution, but was unable to find one Make sure your scanner driver and files are up to date. You might want to uninstall and reinstall the scanner, too. When scanning multiple pages the contrast will fade after the first page and stay that way when using the Black and White document pre-set. Also the page size will only allow for automatic detection instead of specifying the size. The page size boxes are greyed out. Try Acrobat DC. Learn how to edit PDF.
