Dots per inch (dpi) is a recurring term in Los Angeles document scanning services, primarily to determine how clear your scanned file will appear. It’s no good for a scanned file if it cannot be read properly, especially if it was scanned using a low dpi setting. It doesn’t matter if it’s a file or image—it must be clear enough to see.
For print, experts say the standard dpi is set at 300 dpi, which means 300 dots can be fitted in an inch of linear space. Anything that goes below 150 dpi (which is still acceptable according to experts) will come out as blurry as fog. For use in web pages, 96 dpi or even 72 dpi remain as acceptable levels and they load faster. Los Angeles document scanning services take dpi into account when scanning files.
This information is really crucial if you have old pictures you want to upload into the computer. It pays to know at what dpi you plan to scan images and files for the best viewing experience, not to mention for the Web. Simply, the more dots there are for every spatial inch, the more detailed the image or file will come out on the computer.
But keep in mind that a lower dpi means it needs to be small to be clearly seen; a 5x7 picture at 300 dpi will be clearer than the same picture at 96 dpi. If you enlarge an image with the latter dpi, the picture will appear even more blurry since it will have fewer dots per spatial inch to accentuate the details. As of this writing, 300 dpi remains a standard for scanning both images and documents.
You may not have to worry too much about dpi if you’re scanning text documents, but pictures are a different story. Los Angeles document scanning services make sure they scan your files and images while making sure they produce the clearest quality possible. If the service provider uses terms such as pixels per inch (ppi), that’s the same as dpi. The only difference is that ppi, experts say, is less misleading than dpi.
