When you scan a document directly into a PDF file, Acrobat captures all the text and graphics on each page as though they were all just one big graphic image. For some unknown reason, some of the first copies of Acrobat 5 for Windows shipped without the Paper Capture plug-in.
If you find that your Tools menu in Acrobat 5 is missing the Paper Capture item, you need to download and install the Paper Capture plug-in from the Adobe Web site. Note that the Paper Capture plug-in has a page document limit. If you need to process PDF documents over 50 pages in length, you need to look into purchasing Adobe Acrobat Capture, a full-blown version of the Paper Capture plug-in that can handle longer documents.
As it processes the page or pages in the document that you designated, a Paper Capture Plug-In alert dialog box keeps you informed of its progress in preparing and performing the page recognition. When doing the page recognition in a PDF document, the Paper Capture plug-in offers you a choice between the following three Output Style options:. To select a different output style setting, click the Preferences button in the Paper Capture Plug-In dialog box to open the Preferences dialog box.
This dialog box not only enables you to select a new output style in the PDF Output Style pop-up menu but also to designate the primary language used in the text in the Primary OCR Language pop-up menu OCR stands for Optical Character Recognition, which is the kind of software that Paper Capture uses to recognize and convert text captured as a graphic into text that can be searched and edited.
If your PDF document contains graphic images, you can tell Paper Capture how much to compress the images by selecting the maximum resolution in the Downsample Images pop-up menu. This menu offers you three options in addition to None for no compression : Low dpiMedium dpiand High 72 dpi. The Low, Medium, and High options refer to the amount of compression applied to the images, and the values, and 72 dpi dots per inch refer to their resolution and thus their quality.
As always, the higher the amount of compression, the smaller the file size and the lower the image quality. Making Scanned Documents Searchable and Editable.Stuffoholics is supported by its audience. When you purchase through links on our site, we may earn an affiliate commission. Learn More.
How to Scan documents to PDF at a Higher DPI?
We all have memories wrapped inside a shoebox in our basement. Most of those memories are probably childhood photos captured on a film camera. What I mean is you can take those photos out of your basement and store them on your digital device like your computer or your mobile phone.
If you have a scanner, you probably already know this. It becomes one of the hardest decisions to choose the DPI for a picture. DPI determines the detail of the picture, the size of the picture and the size of the file. You have to get your DPI right to get the best version of your paper photograph. You can select the DPI level even on a flatbed scanner.
While choosing the appropriate DPI for your scanner, consider both the file size and the resolution of the image. So, what is the best resolution for scanning photos?
If you use a higher DPI, it will not only create an image with a great resolution but will also be highly detailed and thus will require a good size. You can only perform radical cropping on high-resolution images or the image will pixelate. Read the entire section to know about the best resolution for scanning photos to print.
If you take out one of the photos from your childhood, you can see that every inch of the photo consists of dots. This is because most of the photo labs used only dpi to develop photos.
But which dpi is best for scanning? For example, dpi is considered the best resolution for scanning black and white photos. So, why go for a higher dpi? But when you want to turn that photo into a bigger print, the scanned copy will pixelate.
The best resolution for scanning photos will depend on your business with the photos. Look at these features for each dpi to select which one is the right choice for you:. What is the best dpi for scanning photos? Many people choose the dpi based on the time that is required to scan the photo.
Higher dpi means it needs more time to process. Generally, this is the dpi time ratio on the flatbed scanners:. But the difference between and dpi is significant. This is the average flatbed scanner ratio but there are faster devices too. So, the best dpi for scanning photos depends on your necessity.
Keep some space on your pc to store the photos since higher dpi means it would require more space.What is the best dpi for scanning documents? Grayscale images should be scanned at or above DPI in a. PNG format. Grayscale documents should be saved as a. If the files are for the web, saving them as a. GIF will reduce the file size. See Full Answer. What is the best dpi for scanning photos?

What is a good dpi for scanning? For printers whose resolution is a multiple of dots per inch dpi nothing over pixels per inch for the photo will make any difference when you print, and even ppi looks almost as good.
So for anything you may print at the same size, set the scan resolution for at least ppi and no higher than ppi. What is a good dpi for scanning photos? What file format do scanners use? Since PNG images are losslessyou won't lose any image data when scanning the image.DPI stands for dots-per-inch, and refers to how many pixels are present in each inch of the photograph.
Note that doubling the DPI effectively quadruples the number of pixels, since the dpi increases in both vertical and horizontal directions. For people reading this on a small screen where the image is hard to read, the basic rule is:. Not all photographs are high enough quality to give you a better picture when scanned at very high resolution.
A Kodachrome slide supposedly has enough resolution to output about 20 megapixels. That means you can basically max out a dpi slide scanner and get a good result. Storage is cheap though, so I say scan as high a resolution as you want, and use my rule of thumb as the minimum guideline.
The short answer is TIFF. TIFF was actually designed early on for the purpose of scanning photographs. TIFF is also good because it is so widely supported, and is used by archives and libraries for their own scanning, and is unlikely to become unsupported by future software.
PNG is also a good format for scanning. If you have additional questions about scanning photographs, please post them in the comments below. I would like to be able to print them as well and am wondering if after converting to PDF, would that PDF be good to print from or will I need to sort through the TIFF picture files and organize them to send off to the printer?

The scanner can only scan each horizontal scan line at its optical resolution, like dpi or dpi, however the scanner is rated. To achieve our desired final size, say dpi, this image must be resampled, from say dpi to dpi. Some people claim that we should scan at full optical resolution and resample to the smaller desired size in an external program that is very good at doing it, like Adobe Photoshop.
Others claim that we can scan at less than full optical resolution, but that we should ONLY scan at values of full optical resolution divided by integers 1, 2, 3, 4, 5, etc. So for a dpi scanner, we should scan only at or or or 75 or 60 or 50 dpi instead of "odd" fractional values like 80 or dpi. A dpi scanner offers more choices:, 75, 60, 50 or 40 dpi.
We should scan at the next higher integer value, and then resample the image down to the desired size in a good external program. And some say scan at the desired size and let the scanner resample it. Which software? I resisted the notion of resampling after the scan for a long time.
The photo editor I was using then didn't resample very well I later learnedand I favored the last choice, because the results scanning at dpi always seemed to be as good or better than resampling.
However, I recant my opinion now, there is ample evidence that there are indeed differences sometimes, and you should be aware of it. For some critical images, it certainly might make a difference.
In your archived master copy images, you may want to eliminate all effects of the scanner's resampling. Experimentation is always key. Results can vary. It's likely that Photoshop resamples better than the scanner firmware. But they do vary, and it is possible the scanner resamples better than some lesser programs, giving opposing results for some. Let me show you some samples Some large ones, so it will be clear. These first two were scanned at and dpi. Similar in size, but is an integer divisor, and is not.
Frankly, dpi seems to be about worst case. All images had the same USM sharpening treatment. The first two images are not dependent on image programs, but the third will be affected by choice of software.
The flower's petal edges in the larger dpi scan are not straight and sharp, an effect that is not seen in the dpi scan. It is most visible on angled edges that are neither horizontal nor vertical. It is perceived as a sharpness issue, but it is more due to pixel jaggies than to sharpness. All images had the same USM sharpening.
If you have a x screen or more, you can widen your browser to full screen so the first two images are side by side. Or you can narrow your browser window so the images are one above the other, then you can quickly switch back and forth between them with one scroll click. This image is in fact better than the dpi scan, as is also the dpi scan. It is not better than the dpi, except that it is larger, important if that is the requirement. So there you are.
The way I view the results is that the scanned dpi image is not as good as either of the other two. You will have to experiment for yourself and see if you find advantage one way or the other in your situation.
